ARCTIC Power Bank 2000 Blue - Universal Backup Battery Power bank 2000mAh with 3 years of autonomy tablet before, smartphone and mobile phone (Wireless Phone Accessory)
The battery backup is consistent with the description. It takes a long time to load, but will discharge very quickly for my taste. At best, it can help to fully charge 2 times a sony xperia s smartphone, but not several times as described
