I am using a ZGEAR Power Bank, model PB-U50CIND02A-BKCP. The ZGEAR unit's capacity is 3.7V, 5000 mAh (18.5Wh) and a total of 2.1 Amps Max. I purchased the device as a markdown/closeout item at a Kroger store for $5 - $10. The Voltaic unit you are considering appears to be much more technically advanced.

Thank you. Should work then? May choose one that last longer (i.e. more expensive than base model).
