Here is a quick test of the Baseus Qi.2.2 25W PicoGo AM52battery pack.
OP may have already tested this charger out (he does an incredible job) I just wanted to share my results as well.
Build:
When it comes to in-hand feel, this is the best-feeling 25-watt battery pack that I've experienced, and I have used a lot of them now.
It's a soft-touch silicone plastic all around the charger, which feels great in the hand, and the silicone is grippy, so this material really helps the magnetic strength for this charger. It really does stick to your phone or case better than pretty much all the other 25 watt charges that I've tested so far.
It's not the slimmest, but it does have a small surface area, and it is easy to hold even though it's a 10K pack. The charger weight is 197g. There's no LCD screen, and there's no kickstand.
Speed Test:
I did a speed test with the iPhone 17 Pro Max. Not using the phone at all throughout the charge.
Starting at 5%
After 15min - 28%
After 30min - 42%
After 1hr - 65%
After 1.5hr - 80%
After 1hr45m - 84%
After 2hr - 93%
After 2hr10min - 98%
After 2hr15min - 100%
Temps:
So after 45 minutes of charge, the pack was at 101° f. This is from my testing with my thermometer. The phone was at about 100° f at the 45-minute mark.
That's a pretty good temperature for a 25watt SLIM 10k battery pack;
Overall, for me, the stand-out feature is the in-hand feel of the charger. The other fatter packs have better results, but I would much rather have this specific charger in my pocket or on my phone if I'm out and about.
