Can laptop be charged with power bank?

This Anker PowerCore+ is a 45W PD power bank with a generous 26,800mAh battery capacity, supplied with a 60W PowerPort Atom III USB-C PD charger, which makes it fantastic value.

The Atom III isuseful as a replacement mains charger for your laptop, but also for recharging the power bank itself, which is possible in just four hours - incredible for a power bank of this capacity. Of course, if you already have one, you probably don't want to buy another.

The design is typical Anker and, although it's a little basic, it's impossible to fault. The rectangular brick-like device is, as you might expect, incredibly big and heavy [180x80x24mm and 580g], but its metal body and completely rounded edges make it seem much less offensive.

The PowerCore+ is undoubtedly well-made, and feels like a product that will last. It is also supplied with a mesh carry case and a USB-C cable, making it easier to carry together all the necessary attachments for charging your laptop.

We say charging your laptop, but of course the Anker PowerCore+ has plenty of juice for charging your laptop, phone and tablet all at once. The two full-size USB ports support a 15W output with PowerIQ, which in essence recognises the device type to deliver the optimum charge. Meanwhile, the USB-C port is both input and output, able to deliver or accept up to 45W.

A45W USB PD power bank from Zendure, this X6 has the added functionality of performing as a USB hub while connected to your laptop.And it builds in an LCD readout of exactly how much power remains and four full-size USB outputs, one of which is Quick Charge 3.0-compliant.

Looking a little different to previous Zendure power banks, its softer design is still as tough and rugged as they come. There's a 24-month manufacturer's warranty for peace of mind, too.

In common with all Zendure power banks, there's also passthrough charging, incredible six-month standby, higher-than-average 80 percent efficiency and Zen+ tech that can deliver the optimum charge for your device.

The USB hub functionality is supported on two of the full-size outputs, offering data transfer at speeds of up to 480Mb/s. All four USB outputs can also provide power, with one at 18W and the other three at 12W, sharing a maximum output of 45W.

This is a beast of a power bank. It uses Panasonic graphene composite batteries which the Chargeasap says are also used in Teslas. Theyre fast charging without heating up a lot and can handle 2000 charge cycles, so the only drawback is the price which is, admittedly, steep.

However, look at what you get: a USB-C port with 100W output for charging your MacBook or another USB-C laptop, a second USB-C port offering 60W and two USB-A ports which support Huaweis 22.5W Supercharge, 18W QC 3.0 and Apple fast charge and Oppo / OnePlus Super VOOC [40W].

On the top surface is a 10W wireless charging pad which will charge Qi-compatible phones, as well as headphones such as AirPods, and it will even charge your Apple Watch thanks to a dedicated 2.5W coil.

With the four ports and wireless pad, you can charge five devices simultaneously.

When the 20,000mAh capacity is depleted, the Chargeasap Flash 2.0 will recharge to 80% in just 35 minutes and a full charge takes 70 minutes. Thats assuming you have a suitably powerful 100W USB-C charger, of course: there isnt one supplied in the box.

Lower-power chargers will still charge it, but not as fast.

This capacity can be taken on flights, and the aluminium-clad device weighs 500g. It comes with a mesh carry pouch and is covered by a two-year warranty.

Expect around 70% efficiency, which means a usable capacity of 14,000mAh. Thats enough to charge an iPhone about five times, or a Huawei Matebook X Pro laptop from empty to around 85 percent.

We wish the capacity were a bit higher considering the price, but versatility is the highlight here.
