This is a beast of a power bank. It uses Panasonic graphene composite batteries which the Chargeasap says are also used in Teslas. They’re 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 Huawei’s 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. That’s assuming you have a suitably powerful 100W USB-C charger, of course: there isn’t 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. That’s 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.
