Finding a spot to plug my USB cables into is a never-ending game that gets played out every day; there are simply more cables than I have ports for, and every new generation laptop seems to come with fewer (if any at all). If you’re in the same boat, the Just Mobile AluCharge can help.

Billed as the “world’s slimmest USB charger”, the AluCharge is a pocketable 4-port USB hub that delivers up to 31 Watts with 6.2A total output; that’s a max of 2.4A per port.

Included in the package are the Just Mobile AluCharge and a 2-prong 5′ long charging cable with a built-in Velcro tie.

The Just Mobile AluCharge measures 4″ long by 2.9″ wide by 0.8″ thick, and it weighs 5.9 ounces. Like many Just Mobile products, the exterior is clad in aluminum and it will look lovely with any desktop, but it is specifically geared to look great with Mac products. The two-prong power cable fits into the bottom …

… and there are four fast-charge USB ports on the matte black plastic end.

Its small size and cable with built-in tie make the Just Mobile AluCharge handy for desktop use or travel; I keep mine in my travel bag because having it means I will always have a wall charger handy for every device when I’m away from home.

The Just Mobile AluCharge has a smart over-voltage and over-current protection which auto-detects your devices’ charging requirements so that it can “allocate optimal current for each device’s charging state”. It will get warm to the touch when it is being used because it has been designed to dissipate heat through the aluminum case. The AluCharge supports 100V and 240V charging, so it is ready to travel with you — you’ll just need to convert the power cord plug to the country’s you’re visiting.

If your USB cable charging situation has grown out of hand, then the Just Mobile AluCharge can maximize your charging power on the road or at home.

The Just Mobile AluCharge retails for $49.95 + shipping, and it is available directly from the manufacturer or from Amazon [affiliate link].
