    Awesome little device. Still haven't fully uncharged it. Kind of heavy and long if you want to carry it in a pocket though

    This is the best power bank that I’ve ever owned! It’s very affordable, convenient and it can fully charge 2-3 phones.

    I got this for a vacation where my phone would be getting constant use at a theme park. The battery pack is pretty large and heavy, but it carries 4 full recharges for a cell phone. (I would have preferred the 2-charge Anker but Best Buy didn't have it in stock.) In comparison, my small Anker charger only extends my phone battery's life for a couple of hours--not long enough for 14-16 hours of battery-sucking app usage. Plan to take it along in a backpack, larger purse or tote--it took up so much space in my crossbody bag I couldn't fit my credit card case and cell phone in with it.

    This portable pack is the best ever it’s virtually unkillable. Extremely long life even with constant use while on a plane and the lay overs. Of course the phone previous had an ear Jack and the phone now has the charge port only that doubles for the ear Jack. I don’t do the wireless earphone thing. When you’ve seen an orphan just laying on the ground you know that person is just crying for it’s lost …

    The current model cell phones do not allow for changing out the battery, so this portable charging unit is a need, not a want. It holds up to 6 complete charges, so it is somewhat heavy, but it sure came in very handy during a recent power outage.

    The capacity for these battery banks is blowing my mind. Aye, it takes a while to charge but it's one of those things you hook up before bed and it'll be done when you wake up. I already have a 14k bank to power my gear during conventions and this will serve as a backup. One can never be too prepared! The big plus is this can charge with both ports simultaneously. Not every bank can do that, it's usually only one at a time or it freaks out and shuts down.

    I use this every day. My charger always goes missing at work. So Instead of constantly buying a new charger, I purchased this. I can just leave it on my desk and not have to worry about hunting down an outlet. Or I can leave it in my bag and still charge my phone. When i travel, I can charge my tablet and cellphone, and still have battery power at the end of the day. My only issue is, it is a tad bit heavy. So I can't put it in a small purse.
