This $ 249 power bank with ‘Tesla-designed’ batteries is just bonkers

I have used many power banks in my life, but none of them were too expensive. In India, if you spend anywhere from € 1000-3000 ($ 13- $ 40), you can get a power bank that offers a good mix of ports, charging speed and battery capacity.

So when I got a $ 299 power bank, I was fascinated. For that price, I could get a good budget phone or more than a few power banks. In addition, the company’s claim that it uses the same battery material found in Tesla’s cars, made me want to try it more.

I may not be the target audience for this lavish Chargeasap power bank, but there may be some people who want this.

I have been using this device for several weeks now and it contains some impressive features for a power bank. Let̵

7;s get into the details.

What does it offer?

When you think of a $ 249 power bank, you want it to have all the bells and whistles that a high priced power bank should have. Fortunately, it does.

Chargeasap Flash 2.0 has many features that you can rightly expect at this price. With its capacity of 20,000 mAh, you can charge the iPhone 12 quickly seven times, or the 2020 MacBook Air with a 5100 mAh battery almost four times. That’s a good amount of charging power.

It has a total of four ports: two USB-C ports and two USB-A ports. One USB-C port offers 60W out and the other offers 100W in or out – this is the one you want to use to charge this monster. Both ports support the USB-PD standard.

Two USB-A ports support Qualcomm QuickCharge 3.0 support of 18W. One of them also supports 40W fast charging standards from Oppo and OnePlus and 22.5 W fast charging standards from Vivo and Huawei with compatible phones.

So no matter what device you have, this power bank will support its fast charging standard. That’s a pretty bold claim.

On top of that, the device has wireless charging with dual coil on one side. So you can charge all supported devices at 10W. You can also charge the Apple Watch at 2.5 W.

Design and performance

This power bank is a chonk in every sense. It is 15.1 cm long and 8.2 cm wide. Much bigger than iPhone 12 Pro Max. Flash 2.0 is2.7 cm thick – or about the height of 4 iPhone 12 devices stacked on top of each other.

If you ever need to exercise a little, this device will help you too, because it weighs 500 grams. It is much heavier than your average power bank.

Kraftbanken fulfills its promises of fast charging. It charged my iPhone 12 from 10% to 31% in 10 minutes. It softened up the Pixel 4a from 11% to 48% in 21 minutes; fully charged in under an hour. Flash charge 2019 MacBook Pro 15% in under 20 minutes. So yes. it is really fast and versatile.

Why does it cost so much?

Vinson Leow, the founder of ASAP technology, told me that One of the main reasons why the Flash power bank costs so much is the battery. The company used Graphe battery cells made by Panasonic. This is the same cell that Tesla uses in car batteries.

Originally, Chargeasap used Tesla’s name in the marketing of this product. However, the car company asked to remove the name later.

Leow claims that because of this design you can load or send more power from the power bank. It enables faster charging of devices as well as the power bank itself.

He added that the average power bank lasts 500 charging cycles, which usually works for around two years of use. However, the company claimed that the Flash can last for 2000 charging cycles with these advanced batteries.

Leow said that incorporating all the standards for fast charging is also an expensive process, and that also contributes to the final price.


Chargeasap is aimed at people who already spend more than $ 100 on power banks that charge devices of 60W or more. However, $ 249 is still a steep price for such a device.

The company says that this power bank will last for many years and that you do not need to buy another. If you are a Tesla fan and constantly switch phones, this power bank can serve you well. But if you do not need all these features, there are many options in the range of $ 100 to $ 200 from other companies, including Anchor and Goal Zero that can serve your purpose.
