I admit to loving Ugreen stuff. This company makes some great chargers, cables, and power banks, and this powerbank is no exception. 

At just 5,000 mAh, this is a small power bank, but for a magnetic one designed to hang off the back of your iPhone, that's not a bad thing. The last thing you want is to turn your iPhone into a cumbersome lump. 

There's a USB-C port on the bottom that handles both charging the unit and can be used for charging other devices. The USB-C port supports trickle charging so it can charge low-draw devices such as earbuds without shutting down. This mode can be entered by pressing and holding in the power button for about three seconds.

The front of the unit is coated in a sold silicone rubber than not only feels good to the touch but also prevents scratching your smartphone.

Also: The longest-lasting power bank I've tested also has life-saving features

The Ugreen 5,000mAh magnetic wireless power bank comes in two colors, and if you're happy with the black then you can get a whopping 30% off the regular$30 price tag, making this a total steal.

The power bank also comes with foot-long USB-C-to-USB-C cable, in case you're not already drowning in them. I've carried out all my usual tests on the inputs and outputs, as well as taking thermal measurements of the unit when in us, and it passes all my tests with flying colors.

's buying advice

The Ugreen 5,000mAh slim unit is lightweight, thin, and does the job. And for$30 it's a steal, but if the black version fits in with your style and aesthetic, then you can score an additional$10 off the price.
