That’s because they draw more power than a standard USB-C port can offer. This is where USB-C Power Delivery (PD) comes in. Without going into too great detail, there are two key things to know about PD: first, it is a single-wire protocol that can deliver up to 100W of power; second, that power can go in either direction. In essence this means you can charge power-hungry devices such as Apple’s MacBook, but it also means you can fast-charge the power bank itself. Anker claims that with a USB-C PD charger you can refill this bank in 4.5 hours. That a crazy-short amount of time for such a high-capacity device. See all power bank reviews That all sounds fantastic if you have a USB-C laptop or Nintendo Switch, or you want to be able to charge this power bank in a short amount of time, but what does the Anker PowerCore+ offer to other users? The design is functional but rather basic, a black plastic slab with rounded corners that is heavier than we anticipated at 580g. You certainly won’t want to carry it in a pocket at 180x80x24mm, and you’ll likely feel its presence in a bag.

Anker ships a USB-C-to-USB-C cable and a USB-to-Micro-USB cable. It’s very simple to use, with two full-size USB outputs and the aforementioned USB-C PD input/output on one end, plus a button on the top that is integrated with 10 LEDs. A push of the button will light up these LEDs to show how much power remains inside the bank, and is a decent compromise between the standard four-LED system (which is virtually meaningless for high-capacity banks such as this) and the preferred LCD display (which adds to the price). Despite the button, charging is automatic – you just plug in your phone, tablet, laptop or other device and away it goes. Each of the two full-size USB outputs offer a fast 5V/3A charge, so whichever output you choose you’re going to power up your devices as quickly as is possible. PowerIQ and VoltageBoost technology is also present on these outputs, which means it will recognise your device type and optimise power delivery for it. Passthrough charging is a useful feature for high-capacity power banks, since they tend to be left overnight to refill and you may not have a spare power outlet for also charging your phone or tablet. The Anker does not support passthrough charging, but its power delivery means you could get enough power to charge your phone in around half an hour and won’t need each battery to be fully charged when you run out the door.

With 26,800mAh rated capacity, you can expect a minimum of around 17,500mAh available to power your devices (all lose energy through heat generated and voltage conversion). For most Android phones that’s around seven full charges, or around nine charges for an iPhone (the exact number will depend on your device’s own battery capacity). You’ll get at least one, possibly two, full charges for a laptop or tablet. There’s no doubt that’s a massive amount of portable power, making the Anker PowerCore+ an excellent fit for those who either have high power needs (laptop users and gamers) or those who are going to be away from mains power for an extended period, perhaps for a camping trip or festival.
