RAVPower makes some great smartphone accessories, and this 6700mAh portable charger is no exception. Normally, you have to pick between a wall charger and a portable battery, but this one combines both into a small option that you can easily stuff in any bag. You’ll need to use coupon code SDHP3MSD during checkout to drop the price of it down to just $19.99 today, which is a savings of $7 from its regular price. This is one of the best prices we’ve seen on this charger which was just released late last year.

The 6700mAh internal battery is enough to charge most modern phones and tablets anywhere from 2 – 4 times with ease, and since it has two USB outputs, you can even charge multiple devices at the same time. One port has a 2.4A output, or the charger can output 3A total. While that’s not the fastest that’s out there, the convenience factor here makes a big difference.

There is a display to show how much charge is left on the internal battery, and while you have it plugged into the wall charging your other devices, the battery inside slowly recharges itself as well. RAVPower has added protections to prevent overcharging, overheating, and more, making it safe to use on all of your devices. Be sure to enter the coupon code above to get the full savings here.
