The Euler Promotional Power Bank is our most economical power bank, with a relatively small 2,000 mAh battery. When I first opened up my new Euler, my thoughts were that it was not of great quality. It felt cheaply made and plastic-y. But then again, it is. Keeping this in mind, I proceeded with my examination and testing of it. Size-wise it is very similar to the Watt and Newton branded power banks. I like the rounded shape of it, it fits nicely in my hands and pockets.
When I finished jotting down my initial thoughts, I plugged in The Euler to fully charge it. When I plugged it in, a red flashy light came on. Fifty-four minutes later, the flashing stopped and the red light was solid. The other times that I charged it from empty to full, ranged from one hour and forty-four minutes to one hour and forty-eight minutes.
The first time I charged my phone using the Euler promo power bank, it took one hour and three minutes to charge it from 0% to 74%, at which point the power bank ran out of juice. (There is a blue indicator light that comes on while the power bank is charging something.) My phone has a 2,600 mAh battery so the 74% made perfect sense when you factor in that the Euler only has a 2,000 mAh battery and that some energy is lost in the transfer.
The rest of the times that I charged my phone using the Euler, it took just over an hour to charge it just under 75%.
The imprint area on this promotional power bank is 2.5” x .75”. While not huge, it is more than adequate to show off your company’s name and information. In many instances, it can even fit your complete logo.
Once I got over my first impressions of the Euler promotional power bank, I was actually quite pleased. While it is not the prettiest, does not have the largest battery, and does not feel like it is the best quality, it performed quite well. It was more than enough power to give me that boost to get my phone through the end of the day, without being tied to a wall or computer. Keeping in mind that this is our least expensive option, I feel that it provides a great value for the price.
