Batteries. We love them, but sometimes, we hate them. Countless hours of manpower are spent ever year trying to improve upon a century old technology. As batteries improve at a snail’s pace, there are those of us out there who are in a never ending war with trying to keep our phones alive for even a day. We need a better solution than just buying a second battery for our phone. Enter: the power bank.

What is a power bank? In a nutshell, it’s a giant battery. By giant, I mean 3+ times the size of your phone’s normal battery. The key is finding a way to pack as much battery as you can in as small of a package as possible. A company out there named KMASHI has managed to do this with the KMASHI 20000 mAh Power Bank.

I recently had the opportunity to spend some time with KMASHI’s 20000 mAh Power Bank. Here are my thoughts:


Model Number: Victor K6
Size: 6.69*4.13*0.63in
Weight: 424g
Battery Capacity: 20000 mAh
Battery Type: LG Polymer Li-ion battery
Input: 5V/2A(MAX)
Output 1: QC2.0 5V/2.4A, 9V/2A, 12V/1.5A
Output 2: 5V/2.4A

The KMASHI 20000 mAh power bank is a MASSIVE battery! At that capacity, you could theoretically charge a phone with a 2600 mAh battery roughly 7 times. During my time with the KMASHI, I used it to charge several devices, including:

In my testing, I found that I could charge my BLU Vivo XL (my daily driver) roughly, three times, and the NVIDIA Shield approximately two times, before needing to recharge the KMASHI. Keep in mind, the BLU Vivo’s battery is 3150 mAh, and the NVIDIA Shield’s battery is 5200 mAh. I also liked that I could charge both of these devices simultaneously with no issues. One downside, however, is the absence of passthrough charging, which would let you charge your devices while also charging the power bank at the same time. This would have been an amazing feature to have on top of all of the other stuff this device does.

One feature I loved was the overcharge protection. The KMASHI will automatically turn itself off once a device reaches full charge. This feature is not only great for preventing device overcharge, but it also helps you squeeze every last drop of juice from the battery.


The KMASHI 20000 mAh Power Bank comes equipped with Qualcomm’s Quick Charge 2.0 technology. This feature is AMAZING! I was able to charge a phone that was nearly dead, in about it 1.5 hours. It’s unbelievable. When I first started using this power bank, I would constantly exclaim to my wife how much faster this thing charged my phone than the wall outlet did! If you’ve ever had any doubts, I can tell you wholeheartedly that Quick Charge 2.0 works. Bravo to Qualcomm for inventing something so handy.


The KMASHI 20000 mAh Power Bank is beautiful to look at. It has an all black color scheme with a candy apple red band around the edges. It just looks sexy. It’s also very apparent that KMASHI took a great deal of inspiration from the Samsung Galaxy Note 3 when designing this power bank, and that’s not a bad thing. The plastic the KMASHI uses has the same stitching around the edges that you see on the battery cover of the Note 3. The KMASHI’s plastic also has the rough, faux leather feel that you also find on the Note 3’s battery cover. In terms of build quality, the KMASHI feels excellent. It feels very solid, but I never felt super confident that a drop would not destroy this beautiful device.


The KMASHI boasts two full sized USB ports to use for charging up to two devices simultaneously. I never tried daisy chaining devices, and I would highly advise against it. In between the two USB ports, you will find a micro USB port that you use to charge the power bank itself. Be warned: this battery is huge and takes about 13-14 hours to charge.

On front side of the power bank, you will see a nice LED display that indicates the battery’s remaining charge. I like that KMASHI chose to use Blue for the LED color. It really stands out and is easy to read.

As far as portability goes, the KMASHI 20000 mAh Power Bank feels a little heavy, but when you consider that this is a 20000 mAh battery, the weight suddenly feels very light. The KMASHI is perfect for keeping around the house, taking with you when you go camping, or even just having something at the office to give your phone a quick boost throughout the day. You could, theoretically, put this power bank in your pocket, but more than likely, your pants would fit very weird if you did and would probably fall down, as well. However, 424 grams is a small price to pay for several days worth of device charges in a package the size of a short length paperback novel.



The KMASHI 20000 mAh Power Bank is one of the coolest things I own. It is in my top three favorite devices, in fact. I really tip my hat to KMASHI for making such a quality product that not only works really well, but also works as advertised. Quick Charge 2.0 is phenomenal, and it alone makes this power bank worth the price of admission.

If you’re looking for something that can give you several days worth of charging capability in a small package, look no further than the KMASHI. It works like it says it will, and it is one of the best $33 investments you will ever make.
