Acefast Fast Charge Power Bank M1: Design

  • Palm-sized
  • Unique transparent window
  • A range of color options

You can pick up the Acefast M1 in one of four colors, each featuring a unique transparent 'window' into the device inside. The packaging is flashy and certainly has shelf appeal.

It's lighter and smaller than a regular smartphone, and we found we could hold both the power bank and our smartphone comfortably in one hand. Something that's not possible with the likes of the much more sizable Zendure SuperTank Pro. We found this especially useful when charging up on a walk while navigating with Google Maps. We could also charge our phone in a jacket pocket without noticing any difference in the weight we were carrying.

It's made from fire-resistant polycarbonate that gives it a smooth, shiny finish, and the corners are rounded. If power banks could look 'friendly' — this is how we'd describe it. Though it's made from tough material, we wouldn't want to drop it on anything sharp, like gravel, as we think it would scratch fairly easily, but this isn't something we've tested.

Acefast Fast Charge Power Bank M1: Performance

  • Just under two hours to charge
  • 30W input/output

The power bank arrived with a 46% charge. We drained it completely before charging it back up with an AC charger (not supplied, which is fairly typical of new electronic products). It took just under two hours to charge from 0% to 100%, there is a small green indicator light on the display that shows you when the device itself is charging, and the numbers blink to show progress.

We drained our Google Pixel 7 Pro phone completely to see how well the Acefast M1 performed. The Google Pixel 7 Pro has a 5000 mAh battery, whereas the Acefast has a 1000 mAh capacity, so in theory, we should be able to charge our phone from flat twice. After one full charge of our test phone, there was 36% juice left in the power bank, so we wouldn't quite get another full charge out of it. Remember though, it's unlikely you'll be charging your phone from flat each time, you are more likely to use this power bank to 'keep you topped up' while out and about.

Acefast Fast Charge Power Bank M1: Functionality

The device is small and light enough to carry in the same hand as you're carrying your phone, making it a good 'on-the-go' solution. (Image credit: Future)
  • 12-month warranty
  • USB-A and USB-C port
  • LED numerical percentage indicator

The Acefast power bank features 30W fast charging and is compatible with PD, QC and Samsung Adaptive Fast Charging. There is one USB-C output and one USB-A output, and you can use both at once.

It doesn't offer much more functionality than charging up your devices. There's no flashlight, handwarmer, exact input and output measurements, but it does what it needs to.

The device features various 'protection' to ensure your devices are safe; these range from over-voltage protection, over-charge protection, temperature control technology and more. We tested the power bank with various devices including phones, earbuds, smart watches, headlamps and so on, and didn't encounter any problems.

Should you come across a problem with the device, you have a 12-month warranty, and from our experience, Acefast are easy to communicate with and very happy to assist.

Like most power banks, the Acefast M1 isn't waterproof; for that, you'd need something like the Otterbox Fast Charge Power Pack that is featured in our best powerbanks guide.

Should you buy the Acefast Fast Charge Power Bank M1?

We think the primary use for this power bank is to keep your phone or devices like earbuds topped up for a couple of days. We like that you can hold it in your palm next to your phone comfortably and it doesn't feel like you're holding anything extra at all.

It is also available as a 20000mAh (Acefast M2), which would be more appropriate for longer stints away from home. There isn't a reason we wouldn't recommend it for this type of use, as long as you can find it at a reasonable price, we'd expect to pay around $40.

If the Acefast Fast Charge Power Bank M1 isn't for you:

We've tested a heap of power banks to date and we like different models for different reasons.

For charging multiple devices at once, over a long weekend away, for example, we wouldn't hesitate to recommend the Zendure SuperTank Pro. Though it is obviously much physically bigger, it also has a huge 26,800 mAh  — just under the maximum limit of what you are allowed to carry as hand luggage on a flight.

We also like the Ugreen 25000mAh power bank, another higher-capacity device that looks professional and has a total output of 145W.
