Thought this looked like a good deal for a solar powered powerbank. Available in store only.

Charge Time: 31 hours (Solar)
31 daylight hours ?
That's what I'm thinking. So you might be looking at charging it for a week to get 4,00mah in winter…
I doubt that, more like 31 days.
How much is it normally?
32 daylight hours.
Wouldn't putting this in direct sunlight be bad for the batteries?
No, it’s got a tiny air conditioner inside that keeps the batteries cool.
It says in the manual, "Do not use this… in environment greater than 45 degrees." But Jaycar says you can leave it on the dashboard to charge. Something is not right, because a car will reach 45°C on a 20°C day within 60 minutes.
You can definitely put it on your dashboard in direct sunlight, as long as the car is running….
With the air conditioner on…..
High…..
Using dashboard ventsYep, it also says in the manual that the solar panel is designed for emergency charging. It should not be the primary source of charging. Prolonged exposure to the burning sun will cause damage to the solar panel.
I guess its alright to buy use in an emergency if your regular battery pack goes flat (desert).
Otherwise just stick with a real battery pack.
If you have a dashboard to put this on, and no vehicle battery to charge it from… You got much bigger problems. The amount of capacity this would take out of your vehicle battery is so insignificant, even from the smallest 4 cylinder. You could charge it completely from flat at least a few times before it becomes an issue.
Sounds like a nasty bit of equipment
Why the upvote, unless by nasty you mean "sick", "rad" etc
I can't think of what use this would be?
The mains power is out for an extended period (eg fire, flood) and you want to be able to keep your mobile phone charged.
You're away camping and don't have access to another source of electricity but you want to keep your device charged.Not really a good idea to leave Lithium Ion batteries in the sun for long periods of time though, but I guess if you don't care about premature wear among other things
so you can foresee the future catastrophes and have one of these in your pocket just in case? you didn't really answer my question, just gave me a neg….
Word of warning. Most things I've bought from jaycar are cheap rubbish worth half the price if that. A few have even endangered us.
I'd buy the usb solar panel from Amazon thats regularly $50 ISH and a regular power bank over that 4k risk anyday. I've got two of those set ups on the dashboard of the yatch, so even hotter and sunnier and no fails. Charges a 10k power bank in one day or usb port.
Me too, seems they were hell bent on stocking rubbish and stupidity.
Me three. Lucky Harvey Norman didn’t cancel our yacht orders that day..
…dashboard of the yatch…
Yatch?
Yeah we've got an enclosed cockpit so massive dashboard area
So a yatch is a yacht with a cockpit?
..or some kind of hot hatch@randomusername2017: Clearly you don't know yatchs. Every yatch had a cockpit. Most are not enclosed due to price tag and tiller steering. Ours is enclosed due to no monetary factor and wheel steering. Google yatch cockpit if you need a picture. Then Google enclosed yatch cockpit to understand the difference.
@lette: I also do not know what a hot hatch is. We have two square roof hatches covered with fake Turf ontop for the animals and the motor cabin hatch which is really a very secure door…..
@lette: WOW, that went way over your head… You typed yatch, not yacht. Google yatch all day, no guarantee he will see yachts though.
A hot hatch is a sports version of a hatchback car, played on yatch.
Be more useful as a hammer.
I had a similar solar power bank from big w that worked really well but… (obvious warning) do not leave this in your car in the sun! I forgot I had it charging in the back window and came back an hour later to find it had exploded! (batteries had expanded so much that it pushed the solar panels off)
Insert Ian Malcolm's Jurassic Park quote 'Your scientists were so preoccupied with whether they could, they didn't stop to think if they should.'
Advertised capacity - 4Ah.
Actual capacity after a few charges - probably 3Ah.
My phone's actual capacity - 4Ah.The look on people's face when they realise how useless this is? Priceless.
And not to mention that there are losses in moving energy from one storage unit to another.
This does not look very practical.
I think the whole point of the device is it’s to be used as a normal powerbank and changed through mains with the option of a solar charge in a SHTF type scenario.
This is entirely correct. Its to take camping or hiking just in case the "SHTF"
How SHTF are we talking? With phone battery life as it is, and a power bank, Im thinking this isnt going to help if youre that fubared. Unless you want another game before you fry in the desert / get eaten by your boat mates.
Any natural disaster type stuff Im thinking I would be looking at powering a fridge before a phone, and then I can use that power source to power other stuff, and a car can charge the phone.
It's a powerbank for any USB devices, not just a phone charger.
Although if you're lost, I'd recommend playing 'Google maps' with GPS.
This. You get enough power to your radio or AIS system not a bloody phone that takes a bunch of power. This doesn't even seem useful for FUBAR level of bs.
If it had a detachable panel it would at least show a bit of proper design thought.
Otherwise at this stage safer just sticking to another solar system with a regulated 5V output.
For people who don't see a use for a small emergency power bank that is capable to slowly re-charge itself for an emergency, move along, this is not for you.
For anyone that can use a reasonably low cost, thin and and light emergency power bank with the added optional feature of getting some slow top up charge from the sun, this seems like a decent low cost option for one of the thinnest and lightest solar power banks around.
Well said ozhunter
…apart from the whole lithium left in the sun is a no no.
It's thin and light for a reason. It won't even fully charge a phone once. If you were serious about it, you'd get a 10Ah powerbank and a foldout solar panel that can charge it faster.
"Tally23" The idea for these solar back up power banks is that you mostly charge them via USB and when taking it camping etc you have the option for topping up via the sun whilst away from power source especially in emergency.
"Nukkels" When hiking with camping gear etc the last thing you need is an extra 100-200gms of unnecessary weight when all you want/need to do is top up phone overnight or few days so you can keep phone on for messages/emergencies. I have one similar with 8000mAh cell more than twice the weight and suits my needs, but for many this is better.
Good luck topping up your phone overnight with a solar charger!
It has stellar cells combined with the solar cells in the panel so as long as the night isn’t cloudy it will charge from the stars. Works better in the country than the city.
stellar cells never heard of it? dna lol
