Everyone needs a backpack at some point whether it’s simply to carry your things to work, storing your gear on short weekend getaways, or for other adventures. A constant problem on such trips is maintaining the battery of your smartphone, tablet, digital camera, GPS and other gadgets. This is where the Powerbag shines compared to regular backpacks. It contains a charging system that allows you to recharge any USB powered device from its internal lithium ion battery pack.
This internal battery is designed to be easily removable/replaceable and comes in a 3,000mAh & 6,000mAh capacities. This feature gives the Powerbag the potential to serve its owner well beyond the lifespan of the battery that it originally came with. Unfortunately, the battery pack alone does not have the capabilities to charge anything. It is completely reliant on the backpack to provide power to your devices.
Luckily, this battery does have a neat capability that it can take advantage of while disconnected from the backpack. It has its own dedicated charging port. This means that if a user has two of these batteries, they can utilize one in the backpack to charge their devices while the second battery is being charged separately. For instance, one battery could stay in your hotel room charging while you are out exploring with the Powerbag and your second battery. You then have the option to swap for a full battery when you next return to your room.
This battery is not like most other batteries that recharge your USB devices. Most USB backup battery packs can be charged from any 5-volt USB port. The Powerbag battery requires 12 volts to be charged. In my testing, I was able to charge 2 iPhones, an e-book reader, an action camera, and my 4G/wifi hotspot before the powerbag backpack ran out of juice.
It is recommended that only the included wall charger be used to recharge the Powerbag battery either through the backpack charge port or directly to the battery when removed from the Powerbag. However, if you know enough about wall chargers then you know that all you need to do is find a power plug that matches the output voltage, amperage, and plug type to properly charge any device. Doing so would allow you to utilize a second wall charger, car charger, or even a solar panel. I experimented with utilizing a 12v solar panel to charge this backpack, and it worked out perfectly.
The thing I hate about most backpacks is the lack of quantity and variety of pockets. With the Powerbag backpack, you will never complain of a lack of compartments. This pack has plenty.
I found this backpack to be highly effective, and I would recommend it to anyone with power thirsty gadgets.
