Bought two of these 3 weeks ago: very good price. The first one took a while to charge up fully, but after all it’s a big beast! Reliable and powerful in use, very pleased. But the second one would only half-charge after 4 DAYS! so it was returned for exchange. Even so, I’d recommend it. Good and solid, feels like it will last.

This backup battery is very powerful for its size and extremely good value at the current price. It neatly fits my pocket or manbag so it gives me great backup when I am away from home. I can ride a cycle trail trail for several days and still use my phone camera fearlessly knowing the backup is available for the rest of the trip Highly recommended.
