If you’ve bought a Google Pixel 10 series phone, odds are you’ve been looking at compatible Qi2 and Qi2 25W accessories and wondering what to pick up. A desk charger like the Pixelsnap Charger with Stand, a magnetic wallet, a MagSafe-compatible tripod — all of these are good ideas. But the one accessory I was personally looking forward to the most is a Qi2 power bank. Just snap it on the back of my phone and get a relatively fast charge without any wires or tangles.
I ended up with several of these portable batteries to test out, and while I do appreciate their convenience, one thing stood out in all of my tests: You should really be wary of the battery’s capacity. 10,000mAh won’t be enough to charge your ~5,000mAh Pixel 10, 10 Pro, or 10 Pro XL more than once.

The two portable batteries I’ve been testing come from UGREEN ($89.99 at Amazon) and Baseus ($69.99 at Amazon) — two very well-known brands of power banks and chargers. Both advertise a 10,000mAh cell capacity, Qi2.2 25W wireless charging, and built-in USB-C cables that can go up to 30W for UGREEN and 45W for Baseus.
I drained my Pixel 10 Pro and Pro XL to 0%, took off their cases to avoid any extra heat loss due to the TPU or silicone material, and started charging them. I repeated this with both power banks, both phones, and both charging methods (wireless and with the USB-C cable). You can find the results in the table below.
