The 10000 PD had 18W+10W = 28W, so Anker had the electronics for it, but for the Essential range they did 18W / 10W = 15W. I wasn’t quite sure what you meant by “Don’t expect the circle to completely fill when recharging, the LEDs cover less than half of the curve”. With a 20W USB-C port that packs a real punch, you can charge an iPhone 12, a Galaxy S20, or a PIxel 4 in less than 2 hours. It also gives you the option of charging via a USB-C cable or micro USB — handy if your phone has switched to USB-C and you want to cut down on your clutter of charging cables. The last Powercore I got was the 10000 PD, it has both 18W + 10W output and runs both so 28W output, so this new Powercore is actually less powerful.

It also allows chargers with only 15V support, such as the Switch’s own AC adapter, to recharge this power bank.

Some of the advantages of the Anker PowerCore power banks include high voltage protection, current regulation, and temperature control.if both used then port 1 gets all its needs “first refusal” of Power, and port 2 gets whatever is left but a minimum of 5W 5V 1A. Anker states that this battery should be able to charge a Samsung S10 close to five full times, which converts to around 5.
