STM ChargeTree Go – Portable Wireless Charger

STM are a great accessory maker for mobile devices. Be it bags, protection or simply charging accessories, they cover it all. We previously looked at their ChargeTree Swing product, which lets you charge your iPhone, Apple Watch and Airpods, all wirelessly, off the same device and same output, making charging incredibly easy. The ChargeTree Go takes that one step further in portability.

Look and Feel

The device has a pretty standard shape for such devices, where the phone will sit on front, and the Airpods will sit behind it.

The watch charger is retractable, and easily pops in and out for transport.

The USB C port is at the side, which means you can even use it when it is folded. The front of the device has two LEDs to show which device is charging, which turn on to show you the start of the charge, but then go off soon after while the device keeps charging.

The watch charger has another LED to show its charging status as well.

It folds down quite easily, and can easily be slipped into a pocket or a backpack or a purse. Fairly light as well. STM have also included a handy bag to help you keep the associated USB C together with this.


The usage is as simple as it gets. Just pop your device on and see it charge. Not much more can be said.

More information

More information on the STM ChargeTree Go can be found on the STM website.

Currently, it retails for around £69.99 and can be bought via the likes of Amazon.

It comes in white or black.


It’s hard to fault this device. It does everything it says on the tin, and does it well. A great one for those who travel a lot and need to have a one-stop solution for all their charging needs.
