Bought this in an airport while on vacation when we realized we had forgotten our usual backup brick. When we plugged it in to charge it, the LEDs started flashing non-stop. They would not turn off. The power button seems to have no effect on the device at all. We tried charging it for several hours with it standing on end so the LEDs were hidden but once we unplugged it from the wall the LEDs keep flashing until the power runs out and there is no power coming from the phone/tablet connectors. We tried charging it in the sun (including the full 34 hours it says it needs) and nothing. The tiny blue power indicators never got higher than one dot. The little plastic compass on the back works ok. It's a good concept, just does not deliver.

If you think you might want to buy one of these, take a $20 bill and set it on fire, don't buy this, and you will still be ahead $10.

Was nice at first but I don't think the solar cells ever worked and after a few months I can't even charge using USB. I got like 2 weeks camping trip and then sitting by the window a month or so it has no charge and won't take a charge from a cable.

Garbage

Find another power bank. You can have the unit fully charged - solar or direct power- and it will die within minutes of plugging in phone. After about a month, the unit I purchased didn’t even work; it displayed it was charged but gave no output to phone. Save your $40 for a better product.

Lo compré en un pasillo de aeropuerto en conexión y al comenzar a usarlo ya estaba full carga, logré cargar mi Iphone y el Blu de un compañero de viaje en dos ocasiones estando en 0% ambos, volví a cargar dos veces más y aun le quedaba la marca de una led de carga, trato de recargarlo y me lleva dos días pegado al cargador, lo que indica que definitivamente es buen banco de baterías...

This shit is a fucking rip off the solar panel doesn’t even work as soon as I plug in my phone using the solar charger it dies
