A Very Powerful & Practical Powerbank

This powerbank is very powerful with 20,000mAh while still being extremely practical including having built-in cords as well as the Digital display for the remaining power. It can also charge my devices simultaneously which is very convenient. The design looks nice and it’s not too heavy. Great purchase 🙂

Power some of the things

Overall, this powerbank gets the job done and works as intended. It even charges my MacBook Air M1 at about 13 watts, but you'll need an external cable for that since the built-in USB cable can't handle it.

There are a few downsides, though. The built-in charging cables seem pretty flimsy, and I can't see them lasting long with regular use. The built-in iPhone cable is a bit of a pain to remove without fingernails or something to pry it out with.

Another thing I noticed is that the powerbank gets a bit warm on the output and screen during use. It's not a huge deal, but it's something to keep in mind if you're using it for long periods.

Despite these minor issues, the powerbank is reliable and does its main job well.

Practical power bank

I bought this power bank specifically for the form factor and built in charging cables. These make it convenient to use on the go and while still using the phone. The output supports fast charging for the phone. It serves the intended purpose.

It's a bit lighter than my older power bank of the same capacity, but not enough to notice the difference. The specs state 400g but my scales measured 420g. For comparison my older power bank with specs of 450g measure 455g.

The form factor, with length and width being similar to a phone, makes it possible to stack the phone on top of the power bank and hold in one hand while charging. It's not a grippy surface on top so you need to hold carefully so the phone doesn't fall off if you don't have a rubber type case. My average at best sized male hands found the thickness makes it slightly awkward to grip the phone and power bank together in one hand. Somebody with larger hands would probably be fine.

The built in charging cables seem good quality and are a ribbon style (flat, not round). They slot in to place well when not in use. The length is good for when using the phone sitting on top of the power bank, both when in placed down on a flat surface. The point where the cables connect to the power bank don't give a sense of being overly robust, probably due to being ribbon style. They're fine but I'm not fully confident they will last the life of the power bank itself.

Although not intended for charging laptops, I did find when using the USB-C port with a separate cable that it does charge the laptop. The output wouldn't be enough for a laptop while in use but may still be useful for an emergency charge. Strangely the built in USB-C cable wouldn't charge the laptop so make sure to carry a cable if you want that option available.

The display is bright and clear and indicates when charging, when being charged, and the remaining capacity. The build quality seems good.

Overall, this is a flexible general purpose power bank. With the capacity and output to charge multiple devices, the relatively portable size and being able to hold together with phone in one hand, this is a good option if you only want to carry one power bank that can meet most needs by itself. If you only need a power bank to keep your phone charged on the go it might be better to choose something a bit thinner and lighter (meaning lower capacity) to make for more comfortable usage when stacking them together.
