The era of portable energy is unfolding. From solar rechargers and Stove USB devices like the BioLite to portable battery units like this one, the support many of us have been longing for in our portable electronics is slowly coming to market in dependable and inexpensive fashion.
I’ve used the Anker 2600mAh for several weeks now and at 2.7 oz in diminutive size it is certainly portable. It provides just over 1 full charge to my cell phone and ringing it at under $20 has been well worth the money to me. Their website claims the Anker 2600mAh supports a host of smartphones and devices. It comes with all adapters needed and a charging cable and carrying bag.
