Power banks and alternative portable battery solutions remain to be popular choices for those looking for a way to keep their smartphones and portable devices topped up while on the go. If you're someone who often finds themselves in need of some extra juice and often away from a wall socket, then one option worth checking out is the Aukey 18000 mAh multi-voltage (5v 12v 16v 19v) External Battery Pack.
Straight off the bat, this is a power bank which offers an 18,000 mAh capacity and as a result, should offer those running a device with a 3000 mAh battery, almost six full charge cycles. This is also a dual-USB power bank and this means you can charge more than one device at the same time with each port able to offer a different power output. So if you are looking to charge a smartphone and a tablet (or anything else) at the same time, this charger will ensure they both get the power each device individually needs. This is a power bank that is available for $59.99 on Amazon, although, it is currently on sale for $49.99. What's more is that you can save another $10 off of the price by using coupon code 9KVS4499 during checkout. Bringing the final cost down to only $39.99.
