A portable power station for any situation.

Around our house, we try very hard to be wire-free. That ends up being an impossible task when it comes to recharging devices and/or providing AC power. We have plenty of traditional power strips available and I assure you, they are used to their fullest potential. But sometimes it would be great to have a smaller, more portable power option that can either take the place of some of those bulkier strips or even travel with. ANKER has a great solution with the PowerPort Cube. The cube-shaped power solution features 3 AC outlets and 3 USB charging ports. 

DETAILS

The PowerPort Cube is not your traditional power strip at all. As mentioned above, it is cube-shaped so that larger power adapters have plenty of room without bumping into another large power outlet. The cable is durable and can withstand pressure thanks to its tough coating. The exterior of the charger is flame-retardant and can withstand up to 1382º F. It’s travel-ready since it’s only about the size of a tennis ball and its rounded-corners make it an easy fit in any luggage or carrying case. The cube features overload protection for your devices, too. The cube comes with a short user guide that includes safety and power specifications. An adhesive strip is also shipped with it so that you can affix the device to a desk or other flat surface. The base of the cube does have some very small feet (just enough to elevate it off of a surface), but it’s a smooth plastic bottom so it will slide without the adhesive or other non-slip material. The three USB ports are equipped with PowerIQ, ANKER’s world-famous smart charging technology. It’s designed to deliver a high-speed charge. The PowerPort is backed by ANKER’s 18-month warranty and support system. The PowerPort Cube is available in either black or white.

USER EXPERIENCE

The PowerPort Cube comes in a color-branded box with ANKER’s name printed on it. Aside from the name “PowerPort Cube” printed in small lettering on the side, there is nothing identifying the product inside the box. Ideally, I’d like to at least see the name of the product on the front of the box. When I opened the box, I was surprised at how small the cube actually is. It fits in the palm of my hand and yes, it is roughly the size of a tennis ball. I love the design of it – 1 AC outlet on each side of the cube with the 3 USB ports on the top. The backside has the power cable extension attached at the bottom of the cube and the bottom is bare so that it can sit on a flat surface. The PowerPort power cable comes with a Velcro cable-tie already wrapped around the cable, which is much appreciated. If I had any adjustments, I would make the power cable removable so that it was even more storage-friendly.

As one might imagine, the set-up of this device is extremely simple. You unwrap the power cable and plug it in. Then you can plug items that need power into either the AC outlets or the USB ports. The USB ports are activated by a button on the top of the cube. There is a gentle blue LED that illuminates when the button is activated. The AC outlets can provide up to 1250W of power while the USB ports output up to 5V/3.6A (2.4A max each port). A single USB port can provide the equivalent of a 12W power adapter, but since the three USB ports share power, that power output decreases if more than one USB port is used. This shared power output is fairly standard practice for USB charging hubs.

This type of power output – on either the USB ports or the AC outlets – should be sufficient for most devices you have in your home. Given that devices like space heaters use around 1500W, you will want to stay away from powering them with the PowerPort Cube. I did test the limits of the AC outlets by plugging an electric kettle into one of the AC outlets. The label on the unit states 1250-1500W so I decided to see if the PowerPort Cube could handle the power draw. I let the water heat up in it and when the heating cycle was completed, the kettle shut off automatically. There was no interruption in the power supply to the kettle. And while the cube itself did not overheat, I did notice the cable getting slightly warm to the touch.

As for the USB ports, they seem to function normally. I tested them out by charging a set of headphones and a rechargeable lamp with it. I used a USB Digital Tester to check the output power that was being sent to the devices. First, I plugged the lamp in. When it was plugged in along, the tester registered 5.06V/0.82A. I plugged a set of wireless earbuds into one of the other ports. The tester’s value for the lamp stayed the same. I then plugged the headphones into the tester and got an output reading of 5.13V/0.42A. Since each port can draw up to 2.4A for a total of 3.6A when multiple ports are used, it seems that these two devices were getting their full charging amount even though the cube’s USB ports work off of a shared output power delivery.  I also noticed that when I was only charging using the USB ports, the power cable of the cube stayed cool to the touch. 

CONCLUSION

I’m a big fan of unique charging stations and portable power options. In my opinion, ANKER has created a wonderful little product with the PowerPort Cube. I’ve not had any issues with it and it’s proven to be a helpful charging companion. I do wish that the power cable was removable but other than that, I really don’t have any complaints about this handy little device.
