Hello everyone and welcome to your next Geek Tripp. In this article, I’ll be reviewing the Quantum 10000 mAh USB Type-c External Battery. It’s an inexpensive power bank that utilizes the soon-to-be new standard of USB: type-c. For those who aren’t aware, type-c is the new reversible successor to the micro USB. The downside, of course, being that we have to buy all new chargers, cables and power banks. Unfortunately, there aren’t many options when it comes to USB type-C battery banks. Today, I’ll be reviewing this cost effective option for those in the market.
For $30, I wouldn’t expect much in the way of waterproofing, drop resistance or build quality, but I must say that I was quite impressed. The power bank comes with a glossy, plastic top and a matte rubberized finish on the bottom 90% for a modern and elegant look. It won’t stand up to major drops, but it will be great for day to day use. Both the glossy and matte finishes enjoy taking fingerprints, but the rubberized part that covers the majority of the bank is much better at resisting those smudges. The issue is that once they’re there, they’re tough to get off.
The power bank also comes with a built-in LED flashlight. You activate it be holding down the power button on the bank. It isn’t the best flashlight, but as a simple add-on to a giant battery, I can’t complain. It could be brighter, but it’s capable enough. There are some images below that give you an idea.
Instead of the typical 4 or 5 LED lights to indicate the battery’s charge, the Quantum comes with an actual percentage. As far as it’s accuracy, I’ll be discussing that later.
With this being a relatively medium sized battery bank, don’t expect it to have 10 USB ports. Really, it’s kept pretty simple. There’s one USB Type-c, that is used for both input and output. This is another nice feature of Type-c. It has an output current of 5 volts and 3 amps. This is exactly what the Nexus 6p utilizes in the Nexus version of fast charging. It can also send power. It’s detected which automatically. What’s nice is that you can simply take the cable out of the wall socket (assuming your wall socket is type-c) and stick it right in your phone.
It also comes with a Micro USB port for charging the bank, so if you’re at a friends house with only Micro USB, you’re still able to charge it. Lastly, it has a Qualcomm Quick Charge 2.0 USB port.
I know it seems it’s all love for the Quantum, but unfortunately there is a fatal flaw. When it comes to available juice, it’s primary function might I add, it falls flat. One thing to keep in mind when it comes to the transfer of power, there will always be inefficiency. This means not all of the power output will be utilized. There will be some loss. With that said, Quantum’s 10k mAh battery is only capable of charging my Nexus 6P’s 3400mAh battery once. I would expect a good two charges out of such a large battery. This means over 50% of the battery is being lost in the power transfer. That is simply absurd and should never be the case. The strange thing is that either the percentage given is extremely off, or the battery simply isn’t 10k mAh. The reason being that it’s capable of charging about a percentage every 15 seconds. That’s far too fast for 10k mAh, quick charge or not.
