Backup battery packs are gaining more and more popularity lately. And a big reason for that is the non-removable battery that most devices have these days. External battery packs come in all shapes and sizes, and some have different features which are actually pretty cool. Incipio's OffGrid Portable Qi Backup Battery has a pretty cool feature, that you probably figured out from the name. It can charge via Qi Wireless charging. However, you cannot use it to charge your smartphone wirelessly.
While this battery pack is a bit smaller, and less capacity then a lot of the others out there, it can charge your device at 2.1A, which is the same as Quick Charge. So that if your device supports Quick Charge, then you should be alright. This is a 4,000mAh battery, which can charge most devices around once. Unless you have a device like the LG G4, or Motorola Droid Turbo, which are over 3,000mAh in size.
The OffGrid battery pack is actually a nice looking battery pack. It has a soft-touch plastic feel. Which is nice, as you can hold it next to your device without damaging your device or dropping it. It also has 1 USB port which is 2.1A, and there's a microUSB port which is used to charge the battery pack, obviously. On the front, there is a power button, as well as 4 LED's that light up. Those LED's show you how much battery is left on your battery pack. Now since this is a 4,000mAh battery pack, it charges pretty quickly. Around 2 hours if you plug it in, although with it charging via Qi Wireless Charging, it's going to take a bit longer, which is pretty much a given. Especially for those that have a Qi Wireless Charger and a phone that supports it. You know exactly what I mean.
This battery pack is not cheap, it's actually going for about $69.99 right now over on Amazon. Which you can pick up now. It's a great battery pack, but at $69.99, it's a bit tough to justify, when you have 10,000mAh battery packs going for $10-20.
