Up until recently, that was an issue I constantly experienced. But then came the Anker Nano 30W power bank. It has a 10,000mAh battery capacity, a built-in display that tells you how much power it has, and an ingenious USB-C feature that I can no longer live without.

While MagSafe power banks are now all the rage, if you need to charge anything else, you still need to remember a cable. The Anker Nano has a built-in USB-C cable and two USB ports — one USB-C and one USB-A.

The built-in USB-C cable is a decent length at 0.6ft (19cm) and can be used for both charging the power bank and charging other devices. The cable fits through a metal loop on the power bank, keeping it out of the way when not in use and allowing it to be used as a lanyard loop when you’re not charging anything.

This simple but highly effective feature makes the power bank easy to carry around, especially when your hands are full with other gadgetry. 

There’s a single button on the top of the unit to turn the power bank on. A small but exceptionally vibrant display on the front shows the charge level and estimated charge/discharge time. This is especially useful when you’re powering a phone, tablet, or earbuds and want to know approximately how much time you need before the device tops up.

I carried out my usual barrage of tests on this power bank, testing the capacity, charge, and discharge wattages, recharge times, and how it handled from a temperature point of view when under load, and it passed all the tests with flying colors.
