Product Information

This battery pack has a claimed capacity of 20,000 milliamp-hours (mAh), but we could only get around 67% of that or 13,416 milliamp-hours of this with our simulated load set to pull 2. With a 20,000mAh cell capacity, you can easily keep all of your mobile devices charged up for days on end.

The PowerCore Essential 20000 PD might not be the sexiest gadget around, but it is very neatly done, can be used for a wide variety of devices, including cameras, and gives that all important fast charge ability to the latest phones.This sub is about overnight backcountry backpacking, with a focus on moving efficiently, packing light, generally aiming at a sub 10 pound base weight, and following LNT principles. When the trickle-charging mode is on, the last LED light will remain green, regardless of battery status. With over 50 contributors worldwide, full-time developers, editorial, sales and marketing staff, it is the go-to site for informed opinion and know-how for the quickly changing video, film and content creation industries. We used a high-quality power brick if one wasn't included and timed how long it took a fully depleted battery to recharge for the scores in this metric. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

When I bought it, I found that the multiple phone charges I could get from it made it really useful when I was away from power, especially if I was using GPS on my phone, or I needed to charge more than one device simultaneously. Premium design With a sleek exterior and an LED light wheel to display battery level, PowerCore Essential 20000 PD is premium both inside and out. It feels quite a bit larger than a smartphone and is noticeably less comfortable to carry than a smaller 10,000 milliamp-hour model, making the PowerCore Essential more suited for carrying in a backpack or purse. 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.The USB-C port supports both input and output, so now you can charge your devices, and recharge your PowerCore at high speed. The Anker PowerCore Essential didn't fare too well in this test, earning a score well below average. The latest PowerCore, the PowerCore Essential 20000 PD allows high speed charging, up to 18W on devices that support it. As mentioned, this battery pack is definitely on the heavier side compared to top-ranked portable chargers in our test.
