Rank #2 in Best Magnetic Power Bank 2026: 10 Ranked, 15W vs 7.5W
UGREEN MagFlow Air 10,000mAh Qi2 15W Power Bank
Price and rating as shown on Amazon when we collected them. Both change.
The UGREEN MagFlow Air Ultra-Slim is the second-placed magnetic power bank in this guide, at £44.99. UGREEN sells it as a 10,000mAh pack that measures 13.9mm thick — the listing's own line is that it "looks like a 5000mAh, but actually a 10000mAh" — and claims Qi2 15W wireless charging, a built-in USB-C cable rated at 30W, and 1.6 full charges for an iPhone 17 Pro Max. At 213g and 11.2 x 7 x 1.4cm, it is the sort of pack you are meant to slide into a jeans pocket and forget.
The interesting part is where the listing disagrees with itself. The bullets say "Qi2 15W" and "Qi2 certification" twice, but the specification table underneath lists "Wireless Charging Standard: MagSafe, PMA" and never mentions Qi2 at all. The same table says "Number of Ports: 1", while a bullet describes powering up to three devices at once from an integrated USB-C cable, an additional USB-C port and the wireless pad. And on price, this is the £44.99 model: the guide's UGREEN Zapix at £29.98 declares the same Qi2 15W, so the extra £15 here buys the slim aluminium body and the captive cable rather than more wireless watts. It sits at 4.6 out of 5 from 663 ratings, with 76 of the 100 histogrammed reviews at five stars. Every figure on this page comes from the Amazon listing, not from any test we ran.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“charges my iPhone relatively quickly, I like the wire that comes attached - it makes it almost effortless to top up the charge. slim and fits into my jeans back pockets, whilst attached to my phone. the silicone surface which contacts my phone case is soft so doesn't scratch my case, however it is prone to picking up fluff from my bag/clothes. the magnet is strong, and feels secure - I can hold the battery pack upside down and my phone won't drop, and it takes more than a nudge to shift the battery pack from my MagSafe case. it's more expensive compared to some other battery packs, but I think the wireless charge and the fast charge makes it worth it. it feels like it's made to last. it's perfect for a busy student, and it's great to take travelling - always good to have a 'just in case' power bank whilst out!the corners do scratch really easily, so the grey colour does come off - I used to just put it in my bag, but I keep it in my laptop case now to prevent this (though this is only a cosmetic issue!)”
Verified purchase“Really solid charger, the built in charging cable is convenient and wireless charging speeds is fast!”
