Smarter the phones become, the more hungrier they are for battery. So it makes sense to invest in a good power bank if you are traveling or constantly on move. It also makes sense to have a power bank handy in your bag for you never know when you badly need to make that one call and your phone goes to sleep due to no power.  Power banks comes in various shapes, sizes and capacity and you need to pick the right one to suit your needs.

At our review desk today, we have Astrum Power bank PB25M1A with a capacity of 2500mAh and flaunting a super slim body that can fit even in your wallet. If you have a device that has a battery reading around 2500mAh, this power bank could be a daily commuter with you for the simple reason it is easy to carry around.

Astrum Power bank comes in a sleek package containing only the power bank. No extra cables.


The deal clincher is the slim and neat-looking chasis with smooth curves. It looks good and easily pocketable.


At 7.5mm thickness, it can compliment the smartphone in looks and build quality.


It comes with a built in cable so you don’t have to carry a cable along to charge your Smartphone or accessories like Bluetooth speaker. On the black body, the sea blue cable looks cool and is secured neatly to the body.


When required the cable can be pulled out and then secured back when not in use. Though seemingly it looks to be tightly secured and fastened, whenever pulling the cable out, it looked delicate giving me a nagging feeling it might snap out of the hinges.


There is a indicator which glows red when the power bank is being charged. There is no extra cable with the box, so you need your device cable to charge the power bank.


The same indicator turns blue when the power bank is charging the device.


Didn’t I tell you it fits the wallet easily?


On the technical front, the Astrum PB25M1A powerbank has a input of DV 5V /1A and a output of DC 5V /1A. I would have preferred a 2A output which would have charged the device quicker.

  • Design
  • Built-in cable

thumbs-down-icon  What I did not like

  • Lack of battery level indicator
  • 2A output would have been good.

Nevertheless, what makes Astrum Power bank a good buy is its pocketable nature. When am not carrying a bag, I can easily carry this power bank on my trouser / shirt pocket or my wallet without any bulges.  For daily use as a emergency backup at the end of the day before you hit the home, Astrum Powerbank is a good buy and for more than a day travel, you should be investing on a mightier power bank.
