In this video I take a look at an ecological disaster - a DISPOSABLE powerbank. It's a power bank you use just once to charge your phone and then you trash it. Yes, a plastic box with a battery and a circuitboard trashed after single use. On the top of it, the capacity is very low and it gives my phone only 22% charge! I would have to use 5 such chargers to charge my smartphone fully. This one costs $ 2.20, so just one full charge would cost me $ 11! That's just awesome. It seems that the battery inside is rechargeable, but the powerbank is designed as a one time device just to make more money, with absolutely no respect for the environment.
This one has a universal plug that fits both iPhones and micro USB phones (Android). It says the capacity is 1000 mAh, but a lot is being lost in the converters. It gives my 2600 mAh phone battery a 22% more charge, which is 572 mAh only.
