After my construction efforts I wanted to find a small compact battery to give me a bit of "weekend charge" for my mobile.
As you see from the photo, this new box is about the size of my phone but thicker. It has a 13ah capacity, charges up via a mini USB port the same as all my other kit & can charge up 2 gadgets at a time.. One at 1a, and one at 2.1a. It even charges my new laptop.
Phone battery (Samsung note two) 3ah
Laptop (asus t100) 8.3
So I can charge the phone 4 times or the pc 1.5 times.
Unfortunately I bought it at Amazon perpetuating their reign of slave labour & tax avoidance my only excuse is that a gadget this esoteric nature is hard to come by otherwise.
