Review on Electrovaya Battery Modules by Chris Drury

I like that it's easy for me, my family or friends who don't know much about electronics can use this product with ease! It has saved us more than once when our phones have died unexpectedly during an emergency situation (in which we had no way around).

We've used them as backup power sources while charging mobile devices at first aid stations after hurricanes/tropical storms hit Texas where electricity was cut off from most people because they were without service due to storm damage; also using these modules helped keep cell phone towers up & running longer so calls could be made out even if there wasn’t any line available locally.
