Works with my Samsung Galaxy S25 Ultra, maybe not the fastest way (wired). Magnetic Qi2 connection from both sides (through) is maybe the way for the next generation. (To stack more Qi2 devices, wireless charging the power bank itself etc.)

Anker MagGo Power Bank (10K)

I use it always when playing pokemon go

Last month I really fall in love with Anker products, iam from Czechia and Anker is not that much expanded here, so iam ordering from official Anker website. I have several products, starting with Anker primer powerbank, maggo powerbank and charging station ordered

I haven't had the power bank for a long time, but so far it's been great. The display is very useful in telling the charge percentage along with how long it will take to fully discharge/charge. Wireless and wireless both reach advertised speeds and I haven't had any problems using it with an S25 Ultra.
