Powerful and Reliable

Chargeasap’s Flash does everything it’s supposed to. A power bank with wireless charging, dual USB-A and dual USB-C ports is able to charge up to 5 devices all at the same time without overheating. There is plenty of battery juice between recharges. I love it!

Only powerbank I use to charge all my devices

Looking for a awesome powerbank then look no further.

The flash 2.0 is solid well built and designed power bank with 20,000mAh capacity and wireless charging powered by Panasonic™ graphene battery technology using the same technology as the Tesla batteries use.

It charges from empty to full in around an hour which is extremely impressive. On the front of the device you have a wireless charging pad then on that's hot of the device you have two USB C ports with 60w pd and 100w pd in/out as well as to standard USB ports with QC 3.0 and SVOOC charging meaning your devices will be charged fast. There's also a small screen on the front that tells you the exact percentage charge of your battery.

The chargeasap Flash2.0 the only power bank I can recommend and that I own I've owned many different power banks over the years and the flash 2.0 is the best in every way . It's rugged and well-built has all the latest technology inside it and is the only power bank to contain panasonic's Tesla cell batteries. After sales support from the company is fantastic and they are absolutely lovely and kind people to deal with. I give this device 5 out of 5 .

This review is my own words and thoughts I was not paid by or connected to chargeasap in any way.
