    That's actually a really cool little kit

    • No but I can charge my Kugoo and Xiaomi scooter with it.

      • +1

        It literally can be used to charge a Tesla. But I'm very interested in the math.

        • I was told 600W minimum but haven't tested it myself yet.

        • +10

          a tesla in standby is expected to use about 1% battery in 24 hours which is more power than the tiny solar panel could output. So no it literally couldn't charge a tesla.

          assuming you had an endless supply of fully charged batteries, AND the tesla somehow had no standby power usage at all it would take >500 hours to charge a 75kw tesla using the inverter.

          a 150w inverter is next to useless except for the lowest power devices. it at best could sustain 0.5 amps @ 240v - it won't be boiling water, make toast, running power tools, run a fridge or really anything useful. maybe run a radio or a small fan or a light?

          There's a reason EVs aren't made with a solar panel for a roof - the surface area just isn't enough to make any read difference in change to justify the cost.

            Well nuts.

            Let's call that 2 months with about 8 hours a day of broad daylight. Neat.

            There's a reason EVs aren't made with a solar panel for a roof

            There is one EV, maybe hybrid, that does. So you can run the fan while you're away and keep the cabin cooler/fresh. I forget which but thought it was a neat feature!

          • +2

            @macadamia: When I was a kid, those prototype "electric cars" are almost always made with solar panels all over the body.
            Considering how far pv technology has improved since then, and how it is still not good enough to power EVs, I wonder how useless those ancient solar panels were lol

            • +2

              @Navanod66: The thing is though, those 'solar challenge' type things are made almost like a bicycle so have little to no weight to them - bicycle wheels, carbon fiber panels, open at the bottom and no air con systems. Probably weigh 100kg at most compared to something like a Tesla at 2,000 kg.

              The closest thing coming commercially is the Aptera (https://aptera.us/) which can drive around 60km a day on the power provided by it's own solar panels.

            Hybrids are though. The new Prius is really neat :)

            @macadamia: Agree the 150w invreter is a gimmick..probably mod sine as well (dangerous and useless).

            Get a 250w pure sine wave inverter and run it off your car.

            As for no solar panel roof..it absolutely is being done, and should be stock in all EVs. Think of it like a small jerry can..if you run out of charge..just wait and you will havw 5km soon enough.

            You would easily get 400w from a modern roof mounted solar panel. 1.2kw if you use the boot/ bonnet. But lets use 400w.

            EVs use around 10kwh / 100 km, so.10 000/ 100 = 100wh/ km

            400w for one hour gives you 4km, or 1km range every 15 minutes.

            Parked during an average 8hr work day = 8 *4 km = 32km/ day. Which is about the average daily comute total.

            You wont get 100% efficiency in charging, but a DC solar panel into a DC battery would be good. If you put a windscreen shade up to protect your dashboard (that happens to be a solar panel aa well). Then you are definitely getting 500 watts plus from shade plus roof.

            Again, throw in bpnnet and boot.. 1kw+

            • @tunzafun001: I wish my EV's got 10kWh/100km.

              The most efficient around average about 15kWh/100km, especially if you factor in charging losses.

              I'm pretty sure my Tesla only allows me to go down to 5A (~1200w), so a 150w or 250w inverter wouldn't work.

              • @loksmack: I used to think this, then someone pointed out the 5A rule is the same in the US. So the minimum for a Tesla is 5x110v = 550w
                But you wouldnt be inverting the energy from solar, you would feed it in direct. So would be 300 odd v at just over 1A. Obviously Tesla would need to integrate it.

                But I'm going to build an offgrid solar carport with thrown away panels. The panels will be the roof. Will be an AC inverted output. 600w inverter should do it (will use 2 old car batteries at 24v to smooth out cloud issues, or find a used Hybrid inverter with EPS output).

                • @tunzafun001: Good thought, though the inverter would need to output like 500v.

                  Also, I know many EVSE's (including the Tesla UMC) require ground to work. Unless the inverter ties earth to neutral, then it won't work.

                  There are some EVSE's that do work without ground however.

                  • @loksmack: For the carport? The inverter would just be a normal 240 or 110v inverter. Then you plug your normal EVSE into that.

                    • @tunzafun001: I think we are on slightly different tangents :)

                      I was referring to the theoretical 1A inverter you mentioned. 500v x 1A = 500w (Tesla minimum on 110v). Though it's more likely current limited than total power.

                      Regardless of 240v or 110v inverter, it needs to support 5A minimum, which this Ryobi one doesn't.

                      • @loksmack: Definitely on different tangents. No interest in the Ryobi for anything. Yep, 5A minimum with current hardware. To do with the charging protocol.

                        As for my comments, I was just addressing the statement above that cars don't have solar panels as it wont work, when it absolutely will…and does already in some OS models. No brainer, it will be here soon.I especially like the roofs that extend outwards (like a sunroof that goes outwards both sides, then retracts back in on top of each other). Gives just over 1kw solar input.

                        Lastly, if you are going down the solar panel on a car to charge it route, you wont be using an inverter. It will be a simple DC - DC converter (much more efficient).

        • Not sure why you got negged for that, I was wondering about the sums too. Thank you to above posters!

      Can of worms opened. ;)

  • Title : "21 watt solar panel "

    Description : "a 12W charging rate for ONE+ batteries"

    What am I missing. 12w aint half bad though, particularly vs "nothing". What's that, 1/5th their normal wall chargers?

    • The 12w is low light
      "In low lighting conditions, the Solar Panel can still generate a 12W charging rate"

      • I could almost swear that's been updated since I read it, but all is explained!

      • Sounds like the quoted 21 W capacity is if you place it 1 m away from the sun. Pretty reasonable marketting.

  • +8

    You'd hope for that price it was at least a pure sine inverter… (it's not)

    • You would be correct.

      "It has a standard 240V outlet with a 50Hz modified sine wave output,"

    • You are bloody dreaming at that price! Show me a pure sine inverter in that price bracket plus an 18v 4ah battery 🤣

      • +2

        400w pure sine wave can be had for $99 and Ozito 4.0 is $69 or a kit with 2x 4.0 batteries plus a charger is $100.

        So yes, $199 for the ryobi kit with modified sine “on clearance” is too much.

        • -1

          except you completely missed the solar panel

          • -1

            @azukay: It's a 400W pure sine wave inverter though, compared to 150w

            • -1

              @MikeKulls: its a 21w solar panel though, compared to nothing

          • @azukay: Solar panels get turfed by the thousand every day. CEC ensures you cant upgrade a system..you must replace the lot.

            Contact a solar installer, or look in their skip bin…it will be FULL.

            • @tunzafun001: If you want to cut to size yourself and do some soldering sure, but I'll guarantee you most people would rather just buy a 21w compact solar panel for 2 or 3 day camping trip. You are comparing apples to oranges.

              • +1

                @azukay: Fair enough. I bought a 20w panel from Ebay to power my Brass Monkey car fridge. Works a treat. Super impressed.

                But it is 23w (measured). A heap on Ebay are listed up to 50w..but they would be more like 8 watt.

                • @tunzafun001: Can't trust anything on ebay, at least with ryobi they have support and easy returns from bunnings if it all comes to it. Yes the inverter is rubbish but if someone just needs a 4ah battery and a solar panel it can still work out to be decent. It's not the cheapest but similar 21w folding solar panels are around $70 so it isn't the worst value either. 150w inverter is enough to power basic electronic devices like phones and non gaming laptops.

                • @tunzafun001: care to share what you bought that worked well on ebay? thank you.

                  • @mkkuo: Just had a look and the seller doesnt have one in stock. Looks very much like this. But only $15 (from China)


                    Measures up as 18v 1.3amps. The linked one shows 30w, then says 10w in the description. So dont know. But that is the style I use on my fridge.

  • +2

    What’s the use case for these?

    • “ This little inverter is perfect for what I need. For work or travel, the ability to be able to charge my phone, iPad or laptop is essential. The fact I can now use my existing Ryobi batteries is a bonus and i don't have to rely on a car inverter to do the job. The solar panel is an added bonus too.”

      • +2

        i don't have to rely on a car inverter to do the job

        Your car is DC and your devices charge using DC, why do you have an inverter?

        • Just quoting a review on the Bunnings page.

        • +1

          I’m guessing they’re trying to charge laptop with the AC power adapter that came with the device. So car DC inverted to AC and then converted back to DC in the power adapter.

        • As old mate said they'd be using the AC adaptor. But I just want to add as I've had a similar thought. The voltage would likely need to be converted anyway, which typically means DC to AC to DC (or something similar with switching). So there'll always be a bit of a loss in efficiency

          • @lancesta:

            The voltage would likely need to be converted anyway, which typically means DC to AC to DC

            That's not typical at all. When changing VDC you simply step up or step down DC to DC.

            So there'll always be a bit of a loss in efficiency

            Efficiency loss is a fair bit higher switching DC to AC to DC than DC to DC.

            • @1st-Amendment: Yeah that's definitely true, switching converters are a great invention and the AC laptop charger probably would have one of them anyway (e.g AC->DC->DC), I guess just depends on cost and all that for the person.

      • -3

        Dont use it on Apple devices, or anything valuable for that matter. The cheap ass mod wave inverter is too risky.

        This is trash.

        • No issues with devices, that's the whole point of having an AC adapter. Your macbook or iphone charger might heat up a bit more but those things are indestructible anyway. The devices themselves are fine.

          • @SchnozzBargain: Noise / interference and heat… Things that electronics doesnt enjoy.

            No reason to risk it when a much better and bigger Pure sine wave 200w inverter is $50.

            The fact Ryobi cheaped out with a Mod wave is a HUGE red flag for me. Same as they used plastic tabs to hold the bar on their chainsaws (which snapped on me at the wrong time, and customer service had no care whatsoever). Ryobi are dropping the ball….anyway

            Pure sine wave inverter here.


            Get a 12v solar controller from Ebay for $20 and use that to drop an 18v battery to 12v, and or add a solar panel. If you have a 12v or 14v battery, just hook it up direct.

            Solar panels in the 20w range are cheap as from anywhere.

            If you want a neat battery breakout unit, thingiverse and a 3D printer (I do my prints at a community centre). People offer to print things for a small fee on FB.

            If it was Pure Sine i'd say go for it for convenience/ form factor. But mod wave..nup..

    • +1

      Recharge a non USB-C laptop or battery saw when camping for more than a couple of nights?

    • It'd be hopeless for any real use case. The solar panel is the real weak point here.

      It might be ok for someone living off grid and had nothing else to do but move the panel to face the sun every hour so that they can charge their phone or something. I suspect a typical phone could be charged from 0 - full if sun light was excellent.

    • Agree… does this mean it can only power appliances/things that are less than 150w total?

      I guess I could power my modem and router in a black out… but not internet and tv (tv >150w) at the same time.

      Wifi on its own is pretty useless as I have redundancy with cellular data (4g).

      • Let’s say you could power a tv… how long would you be able to watch tv with a 4Ahr battery (or 2Ah)?

        • I use this inverter to power a projector (and a firestick) and I get around 40min off a 4ah battery. Have rigged up 4 batteries so I can watch a movie/sport

      • Mobile towers don't run forever in outages though, the vast majority run on backup batteries which die eventually unless it's one of the important sites with a generator. Our local tower would always give us about 3-4 hours of usable 4G and then nothing, while our FTTP just keeps chugging along on a generator or battery.

    • I have the inverter ($99 skin only). We use it in the kids cubby house for any little devices they feel like using in there - one of my girls has set up a design studio at the moment and her sewing machine runs on it. I’m using it to power my corded sander on some outside jobs when I couldn’t be bothered to run a line. It will probably come in handy next power outage too…
      So $100 for the battery and solar panel? 🤷‍♂️

    • Having a little crappy inverter and battery (and more ryobi batteries already) can be handy We had a week long power outage when our little hill in Brisbane became an isthmus. There are lots of not very demanding uses, for example:

      1) allows the instant gas hot water to ignite for hot showers (gas was still supplied)
      2) powers stupid electric gates when I want to leave
      3) charges stuff like phones and iPads

      • 2) powers stupid electric gates when I want to leave

        You can install a sealed lead acid battery hooked up to its own solar panel to operate electric gates permanently

        3) charges stuff like phones and iPads

        The 10,000-30,000 mAh portable batteries off Amazon are useful for this and just recharge when power is available. You could just get a semi decent solar panel+inverter and it'll provide better power than this ryobi kit. I think the intent for this is more so lower power device or charge your battery if your a handy man.

    • Well, charging your devices.

      However for the life of me I can’t figure out the use case for the inverter. What can you run in 150W? It isn’t a kettle.maybe a little fan, but why not just have a dc camping fan?

  • +3

    Worst specs ever, at high tier pricing.

  • +1

    Hope Ryobi keep improving and releasing camping products. I can’t bite the bullet on this though, not tempting enough :(

  • +6

    Still seems overpriced for a clearance price to me. $99 and it would be ok to get it for the battery and a toy inverter and panel to play with.

  • +1

    The inverter itself is $99. Hard to think the solar panel is worth $100.

    Edit: Oops. Comes with a battery too.

  • +2

    Would anyone know if the included inverter is the same as this? https://www.bunnings.com.au/ryobi-18v-one-150w-battery-toppe…

    They both have the same name, but I wasn't aware of the above link being able to charge batteries, but rather use a battery's juice to output/charge to other devices. ie. one way only.

    The information in the posted link suggested that inverter can operate two-ways (if that's the correct term).

    • The inverter is different. The one with the solar panel has the USB ports above the power point. The one you linked does not and is different.

      I believe the charging is via a cable from the solar panel (I think it's a smaller DC cable of some sort), not a regular power point.

  • Thankyou so much for posting this deal, I was hoping they’d bring out solar panels for the battery range, woot!

    • +1

      I’m hoping they bring out higher capacity solar panels for them!

      • For sure!

  • +16

    I bought one of these this afternoon- will be returning it asap.

    Maybe I’m a noob, but I expected this to allow both charging/pass through from the solar panel and discharge from the PowerPoint at the same time. It does not - as soon as an input charge is hooked up, the outlets all disable.

    Maybe I was expecting too much

    • I bought one today. As far as I can understand, you can actually plug a USB connection straight into the solar panel, the diagram is on page 8 of the instruction book.
      I can’t see how to add an image here or I would, to show you, cheers

      • +1

        Thanks - yeah, understand you might be able to slow charge USB devices direct from the solar panel but you cannot use the inverter's powerpoint or USB fast charge ports while the solar panels are connected at the same time.

        UPDATE: returned with no issues.

  • This is a good idea. How well does it work for camping off-grid?

    • Terrible. 150W max output isn't much (at best a fan at low speed). And the battery is only 72Wh (same as those 20000mAh power bank). If you run full 150W, the battery will be flat in 30 minutes. Then you need 3 - 4 hours of full sunlight to charge it back up.

      • and to make things worse, from the comment above apparently you can't even use it while charging.

        • You can plug a device straight into the solar panel to charge directly, it shows a diagram of that on page 8 of the instruction manual.

      • At it's very best ever, in the best solar conditions, with the correct aspect and orientation the PV panel may just about charge the battery in 4-5 hours.

      • +1

        Most pedestal fans max out about 45w so you do get a couple of hours out of it. I have the non solar model.

  • Is this one of the most pointless things ever? Who would need something like this and willing to pay $300, at that point you just buy an actual power bank.

    • I think the useless 2 port USB charger that came in one of my Ozito kits is probably more useful than this.

  • +1

    Genuinely curious as to what other alternatives for panel + battery there are at the sub $500 range for the more knowledgeable folk here.

  • I have the original Inverter set up minus the solar and while rated @ 150w I would take that with a grain of salt. In my experience around 80w is a stretch. So curb your expectations. Maybe this version may have been improved. Read the reviews.

  • Too bad we don't have a 12V version like in the USA which would allow you to plug a camping fridge into a 18V ryobi battery.

    • You can do this easily with a 12v buck.

  • +1

    Aside from the whole tooling ecosystem where they try to lock you into a battery brand, I'm pretty chuffed with the variety of products these days. It is really handy to have a set of high-chooch batteries that suit a set of tools and appliances. Next on my list is an angle grinder.

  • +1

    Dunno about the whole solar situation but we love our 150W inverter on it's own. Will keep the NBN modem and our router running for at least 3-4 hours per battery, and can charge phones and laptops off it on the go as well.

    I usually take it with me when I'm out and about with the drone, as soon as the batteries are empty I can just plug them in and then drive to the next location, ended up being cheaper and much more portable than a 12V inverter.

  • +1

    If anyone is just after the skin, an AliExpress inverter could be an option. Will be cheaper with 11.11 day.


  • I want to power and charge my Moebot S5 robot mower. Can I use this kit for the purpose?

  • Thanks i bought one
    The solar panel is simply usb not a specific connector.

    The battery charger can therefore be used on 5v/12v charger that works on my pc usb a and usb c

    And of course car usb.

    I didn't really need the inverter function or battery but that i got as kit

    It is sadly only able to charge the battery or power inverter at one time.
    So if I need to power the 240v fan in the shed must unplug the usbc

    • Hey are you to test if the USB output can be 12v? Thinking use this to power 12v camp lights. Thanks

      • there are no dedicated 12v ports, 2 USB-A and 1 USB-c
        When the AC port/inverter is activated , the USB-c port becomes activated and can charge my laptop and phone at reported rate of 12,000-13,000 millliwatts

        but I do not know if that is 12v 1amp or 5v 2.4 amp

        but that is certainly a slow charge rate
