RAVPower has discounted one of its very versatile portable chargers today, bringing the 26800mAh capacity model down from its listed price of $79.99 to just $52 when you use the promo code PB058BCM at checkout. That's a great price for this battery pack, especially since it does have PD or Power Delivery included.
This battery pack from RAVPower is definitely a good one to grab as a stocking stuffer this holiday season. There are two USB-A ports here, a USB-C port and a micro USB port. The USB-C port is the one that is really interesting here. It's a Power Delivery or PD port, which means it can do both input and output. So you could charge the battery pack with a USB port, but also use the USB port to charge your smartphone. Since it is PD, it also has speeds fast enough to charge larger items like a laptop or a Nintendo Switch which use USB-C, and you don't need to be tied to a wall outlet while its charging. There is also 26800mAh capacity here, which is more than enough to get your phone charged up quite a few times.
