Customer Review

I use it for various apparatus (GSM, GPS hiking, tablet ...). Really useful when you know you will have an intensive use of these consuming devices without using energy to recharge the sector. Ability: beware, most other products have a significantly lower capacity. The two USB ports are a great addition, they allow you to connect two devices simultaneously (for me it is often the GSM + GPS).
