Review: EasyAcc Monster 20000mAh Power Bank

First of all thanks to EasyAcc for the sample. My unit is the black and orange colour combination but there is a black and grey option as well.

So quite a while ago I reviewed the EasyAcc PB10000CF (find it here) which was by all means a great product and a great step up from the EasyAcc PB10000. And for me it worked perfectly, however I know there are others out there who require more than 10,000mAh of external juicy goodness. Hint where the EasyAcc Monster 20000mAh battery bank comes in.

Of course coming in at 167x80x22mm it is no means the most compact device but with 4x USB out ports, LED and 2x micro USB in ports it is certainly full of features.

In the box you get:

  • The EasyAcc Monster 20000mAh External Battery Bank
  • 2x Micro USB cables
  • Instruction manual


Everything that comes in the box.

Taking a look round the device, up front there are 4 USB ports, (that each support smart charging, a feature that appears to be on every new version of every power bank) as well as super bright LED. Turning it to the right there is 2 micro USB ports to charge the device. Turning it to the right again there is nothing there. Giving it another spin the right again there is the power button to check the battery indicator. You check the battery by pressing it once and pressing it twice will turn on the LED and press it twice again it’ll turn the LED off.

The 4 outputs can charge 4 devices at once as long as the total amps don’t exceeded 8amps. I also mentioned two USB in ports which is used to charge the device in 6 hours at 4 amps (2amps per input). This in my testing it does appear to take 6 hours. For me this is fine as I charge my power banks overnight so that they are ready for used the following day.

Around the device

All the ports.

Now if you’re like me and you ride a motorcycle you probably don’t have a 12 volt socket, which is a bit of a problem considering we live in a day and age where we use so many mobile devices. So I tend to use my power banks to charge my phone whilst I’m riding and I tend slide my phone and charger into my inside jacket pocket, keeping the power bank and my device from the damp. With this power bank I can… just.

It is doable but I wouldn’t want to do it for too long a distance as it noticeable and means I have to jig around to get it to sit comfortable. But never the less it works. It would be nicer if it was a little thinner but that would probably mean sacrificing a couple of milliamp hours, but hey ho it works and at £23.99 for the orange and black it is quite reasonably priced but for the black and grey it is £27.99. Now I don’t understand why the different colours cost £4 different but I don’t think I’d pay £27.99 but to me it’s just a waste of money to pay the extra for a different choice of colour options when they are basically the same thing. It’s up to you.

The two color available options.

So to round it all up, the EasyAcc Monster 20000 is a good power bank that gets the job done. The fact it features smart charging gives it some great functionality. The design despite being a bit thick does however still work well. Would you recommend the power bank? In one word, yes. It does sit mid-price for its capacity but it just works and it works well.

For more information, take a look at EasyAcc’s website. Found here.
