The EasyAcc portable charger is a no-fuss, simple charger with great features. The 6,400mAh capacity is plenty to give my iPhone 6+ two full charges (we'l get to the numbers later). The iPhone 6+ is already has excellent battery life, but this makes it all the better. It feels well constructed and has a nice, smooth finish, giving it a nice, solid feel in the hands. The footprint is very small and easy to carry. The one thing I particularly like about this model is that it has a single 2.1A x 5V USB output which is best for rapid charging with a 2A x 5V input USB-micro input for charging the charger. There's also an LED for flashlight mode, which can be redundant if you have a smartphone, but it doesn't hurt anything to have it there. There are 4 blue LED lights around a single on/off button which give the status:
4: 75-100% Capacity Remaining
3: 50-75% Capacity Remaining
2: 25-50% Capacity Remaining
1: 5-25% Capacity Remaining
Blink: 0-5% Capacity Remaining
For real-world usage data, I used my trusty iPhone 6+ on iOS 8 with Wi-Fi on and Bluetooth on. I took several calls, checked e-mail, browsed the web and played a game or two during each charge (since you'd likely be using it if you're charging, at least I do.)
Charge iPhone from 36% to 100% took 1:21 hours to charge. Charger went from 4 lights to 2.
Charge iPhone from 29% to 100% took 1:44 hours to charge. Charger went from 2 lights to blinking.
If you weren't using the phone during charging, you could theoretically get two full charges on the iPhone 6+, but I was pretty happy with these numbers.
Overall, you can't go wrong with this charger. It's the best balance of price vs. features and does and excellent job on delivering. I highly recommend it if you are looking for an excellent charger.
