Cooler Master Power Fort 6600mAh Review

Our smartphones have died on us on long trips one way or another. There are a lot of external power options out there in the market today. Today, we’re reviewing the Cooler Master Power Fort 6600mAh variant.


Cooler Master offers the Power Fort in 2 colors: Black and White. The packaging is simple enough with ample details for the normal consumer to consider getting it.

Here are the specs written on the back of the packaging:

Power Capacity: 6600mAh
USB Input: DC 5V/1A
USB Output 1: DC 5V/1A
USB Output 2: DC 5V/2.1A
Dimensions: 11.5×9.1×1.7cm
Battery Type: Lithium-Polymer
Recharging Time: 9 hours
Weight: 178g
Operating Temps: ““10C to 45C

Yes, there are 2 USB outputs on the Power Fort. The other one is rated at 2.1A, targeted for tablets which needs higher power capacity or in the case of newer smartphones, the Galaxy S4 requires 2.0A also, which I used for testing this power bank.

As you can also see, the Power Fort is very portable and lightweight to carry on long trips with you. It’s barely the size of a wallet.


The packaging contains the Power Fort unit, a stylish carry case, a usb cable, and tablet plugs compatible with iDevices that use the 30-pin cable, but you can plug any USB cable that you use. Take note though there are USB cables that provide power only, which is great for charging as it maximizes the devices power output, leading to faster charge times, as opposed to USB data cables, which sometimes cuts your charge rate in half or even 1/3 the regular time.


The Power Fort is pretty straightforward. On the left side, you’ll see the ports: 2 USB Output, 1 micro-USB input. Underneath there’s a label saying which port are which. On the top side, you’ll see 4 LED dots that indicate if the unit is charging and the power level. 4 Dots means around 80% to 100% of charge, and around 20% to 40% if there are 2 dots and certainly less than 20% power if there’s only 1 dot remaining.


Now here’s the meat of the review. How does the Power Fort measure in real life situations? The packaging says recharge time of 7-9 hours, so when I received the unit, I had it discharged and when I got home, I left it to charge overnight, via USB.

I’m using a Galaxy S4 and a 5th Generation iPod Touch on my everyday routine to work. The Galaxy S4’s battery has 2,600 of capacity, doing simple math, it can recharge my phone 3x, with the last one charging around 50% of my battery, and the iPod Touch 5th gen carries a 1,030 mAh juice. And the Power Fort was able to deliver on its promise. I was able to charge my Galaxy S4 twice to full power, having my device discharge battery to 15% and my iPod from 0% to 100% all in one go. Yes, you can charge 2 devices at the same time.

You don’t have to worry about overcharging as the Power Fort 6600 comes with a special circuit design that prevents damage to your precious devices from over charging/over voltage.


The Cooler Master Power Fort is a perfect companion for long travels wherein you doubt the existence of power outlets. Investing in a good external battery backup can save your trips without the worry of having to look for coffee shops or fast food chains offering free charging stations or convenience stores charging you by the minute.

SRP for the Cooler Master Power Fort is P2,799 and you can buy one from Octagon.
