LeTouch 3250 mAh external battery is super slim and it weights only 3.5 oz. It comes with a short (3.5") built-in cable and it chargers my phone at a good clip (9% in 10 minutes). I run this the same test on all external batteries with built-on cable (since I cannot use a current monitor on these cables). I run the test with phone battery at the same level running the same apps so I can compare different batteries to each other and it compares well with the other batteries running the same test. Its capacity is only 3200 mAh and some of it wasted towards heat, but it is just enough to fully charge my phone with a large battery. It also works very well with my MP3 player. When I have it along on my exercise walks I want a battery that it very small and light and LeTouch works very well.
This battery has a charge level indicator (some slim batteries like Le Touch 1350mAh give up this feature) but to me a charge level indicator is very helpful so I have an idea that the battery is about to run out of juice, so I am glad that Le Touch 3500mAh has it.
When you don't need a power house charger and weight/size matters this battery is just the right thing.
