We charged using a 5V/2A (10W) and a 5V/3A (15A) USB charger, and results were better – around 10/7 hours all up.
LED Torch and compass
It’s a 2 LED torch producing about 500 lumens. The beam is broad rather than focused. The compass is a little small for navigation.
GadgetGuy’s take: Uniden UPP80S solar power bank works if you have time
If you realise that the solar panel is for top up of the 8000mAh power bank and you are probably paying about a $10 premium over a standard power bank, then it’s a great device.
If you expect miracles, then I suspect that such a device would a) be too big to cart around and b) technology is not far enough advanced to invent it yet.
Check out our review of the Choetech 24W portable solar panel – it is nearly perfect, and this battery would be a great accompaniment.
