What better way to test your aliexpress chargers/cables than with an aliexpress voltmeter? Cheapest FNB58 I could find, reviews for this model are quite good and supports most of the popular protocols

Shop owner, that's why they got an electric shocki
Umm… I've tested these…
They're pretty good. These for the longest time were the best option you could get, but if you want something better simpler and cleaner there are options from AVHzY, WITRN, Charger Lab Power-X. They can be more expensive but they're better built, more stable and overall a better product if you're going to utilize these to their full extent.
They also have inline USB-C options so you don't need additional cables.
If you just need a watt reading, there are cables that show wattage on the port that are much cheaper and a better option for many.
Any Aliexpress stores and/or product listings you can link to that have been reliable?
I got something like this
https://vi.aliexpress.com/item/1005005210545584.html
which is a cheaper and has all the necessary accessories.The thing is with USB-PD, different manufacturers
have different 'implementations' of the PD.How is it? Seems to have a lot of connectors - is there any combo it can't do?
It was case of BFTL , haha
It's pretty good, but the UI is a bit tricky
but otherwise, it was useful to determining
some charging cables being at transferring power.The issue will be due to USB-PD ,
because different brands (eg. Huaweii, Qualcomm, etc.)
all have different USB-PD implementations,
and the USB-PD voltmeters are actually quite pricey right now.
Balls Frozen To Leg? How would a USB voltmeter help with that?

I got this as a cheaper option vs the FNB58B, it's OK for non PD stuff but I kinda wish I just went with the FNB instead.
I also wished I went with the FNB,
because it has nice graphs.@whyisave: I'd like to have more PD and fast charge functions. Not sure whether it's worth dropping the extra on the bluetooth version too even though rarely use it, but nice to have. Also a faster shipping seller. Can't do the 2 month wait any more after recent fast shipping orders arriving in around a week.
@bamzero: Bluetooth is very convenient thing to have,
but it's one more thing to go 'wrong', i guess.I like wired connections for reliability.
So, I don't bother with the Bluetooth,
because you would need to download their Apps onto your phone,
and their Apps are usually buggy, not well-maintained
and probably have backdoors, ha.
Really amazing how many inputs, outputs and tests it can do.
damn thats pretty cool - tempted to get one
That's not exactly right since they're not PD
PD is a defined spec.
Other "implementations" do not fall under PD, the Chinese brands like Huaweii, OPPO, etc that have their own proprietary charging protocols are completely seperate standards.
I thought PD was a defined specification too.
Until I saw the voltmeters that started defining "which" proprietary PD voltages it could read,
so from that, I deduced the fact that different brands have different implementations.That voltmeter- https://vi.aliexpress.com/item/1005005210545584.html
had to included a separate USB-PD reader, but with caveats too.
PD is a defined spec, those other standards are not PD - that's the whole point.
That separate device is a PD trigger, not a voltmeter.
A lot of people might be happy with a cable that has a watt indicator..
Cheaper and easierhttps://vi.aliexpress.com/item/1005005720283526.html
Yes, these cables are much cheaper, practical and
show the power usage at the charging point
(and not at the power-adapter point, where it's 'hidden' away).
If you just need voltage and power, there is a common USB-C V/A meter for around $5, e.g.
Watt indicators aren't very useful to determine total mAh eg. if one wanted to check battery capacity or total charge received.
A decent cheapie one (for lower volts/amps tests (4~20V 0~3A)) is the Keiwsi KWS-V20 type testers. Handy gadget to record total mAh sent to device and time required. They do a decent enough job and fairly accurate for the novice.
I’ve found the inline one I bought on eBay for $17 last year to be much more convenient as I can test and discard (or at least avoid) some of the trashier cables I’ve collected over the years.
I have one of these, they're pretty good.
Good to be able to plug in a charger and it'll tell you what voltages/wattages it supports and quick charge protocols
Big Clive would be proud.
How do these compare to a AVHzY, aside from being cheaper?
Having used both - they're both about the same. I'd get this one cause it's cheaper, does almost everything the AVHzY one does.
Got one, thanks!
Shocking deal
Watt do you like about the deal ?
The amp-le discount
Does anyone know if the screen is touch screen?
Touch screen…..for what purpose?
Most of these devices have an option change modes, or flip the screen the right way up.
A touch screen is overkill though, as this can all be done with a single button with short- and long-presses,
No
I have something similar to this, and it's a great tool to test output.
Got a refund one time too due to cable not even doing 1A charging, only 0.5A with a ~20% battery.
I want a really good one of these that isn't 120 dollars.
Test cables ability and confirm USB port power draw and possibilities.
Does this fit the bill?
Yep Cable info, power supply capabilities. Pretty much everything you need (until they add yet another protocol)
Thanks, I'll give it a try!
That's a decent feature indeed.
This will be great when I compete with Big Clive
I have this one. It works well and less than third of the price of this deal.
https://vi.aliexpress.com/item/32816538942.html
I got the Bluetooth one for ~$63. Pretty average app though, you're not missing much.
Just get one of these suckers: https://vi.aliexpress.com/item/1005006073086097.html
$5 + delivery. Works as intended. Seems to be a clone of this well-reviewed one from Plugable: https://www.amazon.com.au/Plugable-Amperage-Direction-Indica…
I've found charge meter to be quite good. Obviously it only works on devices it's installed on.
https://play.google.com/store/apps/details?id=dev.km.android…why not just use an app on your phone, thats how ive known for years which cables and chargers arent working up to par
What app {Android} do you suggest ?
I only care about whether a charge cable or charger is working at expected rate, i have no idea why you would need anything else or perhaps some people just like screens on stuff and watching graphs….bonus about the app is that it wont sit in the 3rd drawer down for the rest of its life a week after you get it on the slow boat…
The better apps are (in no order)
Battery Guru (sadly removed from play store, but here: https://www.paget96projects.com/battery-guru-download.html)
AccuBattery (https://play.google.com/store/apps/details?id=com.digibites.…)
Thanks will have a look :)
i have no idea why you would need anything else
Then this deal is not for you.
People who need this - not just a phone app - will know why they need it.
An Android app is not at all the same thing. These devices are used for testing multiple things and not just to see if your mobile is charging. If all you are interested in seeing how your Mobile is charging, then all good.
If you however wanted to check the capacity of your battery from 0% to 100% you can't use an app for that as phone needs to be off to test properly. Likewise if one wanted to test a Powerbank capacity etc etc. They don't have an OS!
