It's not 100,000mAh, it's not 10,000mAh, the solar panel is mediocre and the output certainly isn't 2.1A. But other than that it's actually quite usable, and has an interestingly minimalist chip that manages charge, boost converter, status LEDs and flashlight LED all with just 8 pins. Note that there's no cell protection option fitted on the PCB so it's designed for reuse of standard phone batteries that usually have that protection built in.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

I think that case is actually pretty nice for some Arduino or some other electronics projects. Under 3£ I'd be more than happy to pick that up.
i have a battery with a solar panel on it and yeah, the output is almost useless, almost.
I need something like that to charge Lithium batt for a small Bluetooth speaker
I’ve gotten my hands on a number of little power banks with solar panels… I’ve always been disappointed, they’re usually worthless when it comes to trying to actually charge the bank… might keep the LED working?
Good morning Mr Clive! Have a great day!
looking at doing something w/ solar but watching you solder makes me realize I've been doing it wrong lol
I'll bet that the absurd mAH rating was considering the current supplied by the solar panel for some absurdly long period of the sun hitting it…
My co-worker had one of these. It was labeled 100,000 picowatts!! I just started laughing.
I was waiting to see the glow bugs jump out like on james and the giant peach
@bigclivedotcom – it appears to me the 2 solar panels are different technologies – TFS or Thin Film Silicon, and the other is a CZ ( can't tell if it is single-crystal silicon or polysilicon ). The two technologies have very different spectra responses. It is possible they would respond better outside. Because, depending on your inside light source and its spectral content, one solar cell/panel will perform better than the other ( I think the CZ or polysilicon is more responsive to blue and the TFS device has a better response to red ).
Seems very few of these output rated current
100k mini Ampere-hours
the casing is for a pocket hdd originally
I bought one these before I found this smart guy,annnd it's junk,battery wrapped in silver is ok,the solar cell jumk
100,000mAh ? lol
this looks awesome to use with in field deployment of arduino stuff. like a wifi enabled temperature sensor in the garden or mesh network LoRa devices for private communication
NIce!
