Review: myCharge AmpProng – A Powerbank That You Will Actually Want To Take Around the Office

[ 0 ] Posted by on September 21, 2015


With so many portable powerbanks on the market these days, it’s easy for the average consumer to purchase one that is not suited to their needs. Thankfully a company called myCharge is here to help. They offer a variety of different powerbanks for an assortment of users. In this review, we will be checking out the myCharge Amp Prong. A powerbank with a built in AC prong. This particular unit is ideal for those of you living in North America.

The AmpProng has a built in 3000 mAh battery that myCharge claims can provide 22 hours of  battery life to any device it’s used with. We put those claims to the test, and the results are below for those looking to purchase this handy device.

Design and Features


The AmpProng we received comes in a lab coat white color, with a dark steel gray running along the bottom and up on the sides. It’s quite pleasant on the eyes. On the left side of the device we have a single USB port that features 2.1A output, allowing users to charge power hungry devices such as tablets.


 To the right side, the AC prongs that pop out of the device. Along the top is a small silver square button, with a strip of 4 LED’s placed half an inch  after it. When pressed, those LED’s light up for a few seconds to display how much charge is left in the battery.



The AmpProng feels like a fairly solid device, despite being designed for pedestrian applications like running around the office or meandering around the living room. It’s body is made of strong plastic that feels very nice to hold. At 0.17 lbs, it’s practically half the weight of an iPhone 4S. This weight does add to the overall feeling of solidness to the whole unit. While running around with it in my bag, I never felt as though I was carrying additional weight. Noticeably absent is the lack of a mini USB charging port. This is problematic as it means the only way to charge this device is via a proper AC outlet. This can be problematic if you are in a car, or happen to be anywhere else where you have access to USB charging – and nothing else – for long periods of time.

Battery Life

Utilizing a 3000 mAh Lithium Ion battery that myCharge claims will provide “22 extra hours of power”  after a month of testing, it turns out the AmpProng does not quite deliver the 22 hours of promised runtime per charge. In fact it’s a lot closer to 7 hours on average. This is because the devices you will probably charge via this powerbank are going to eat way more battery power than you realize. Even 7 is something of a stretch. I often found the battery losing power a lot faster then that. The AmpProng does charge extraordinarily fast, going from empty to full in about 3 hours – thanks to something myCharge calls “Rapid-Recharge”. Additionally it recharges devices quite quickly using “Hyper-Charge”. The reason for the performance is simple. The bigger your devices battery, the more power it will require to fully charge. A device that uses a 1500 mAh battery could conceivably get 2 full charges out of the my AmpProng’s 3000 mAh battery. The “22 hour” claim comes from the fact that, if your iPhone is fully charged, it should run for about 11 hours of practical use throughout the day. Combine this with the 3000 mAh battery in the AmpProng, and users could get 22 hours of total run time. However it’s more likely that if you were charging something with a smaller battery, such as a pair of wireless headphones, that you could conceivably see such gains in terms of power. So in short – 22 hours is not realistic.

Overall Usage

However the saving grace on this device is the inclusion of the wall adapter, which made it incredibly simple to both charge the powerbank and my smartphone / tablet / headphones while taking short breaks around the office, or around the house. It was convenient and it did add substantial value to the devices shortcomings in terms of battery life. In practical usage, I was able to recharge my phone way quicker than i would have via the standard charger. And the AmpCharge itself was always quick to recharge. Additionally, the inclusion of pass through charging was especially useful, as many powerbank’s often lack this basic feature.

Final Thoughts

At $39 USD, it’s a little pricy for a powerbank that is not loaded with a ton of features. However for those of you that fancy yourselves “Desk Warriors” this could be the perfect device since it’s small, light,  and should provide plenty of juice to power your smartphone through a full day of work and then some.

In one sentence:

The ideal power bank for those office jockeys that require on the go power and design convenience.”
