Home/iPhone/Power Banks/TORRAS MiniMag 10,000mAh Magnetic
Snap it on, keep using your phone, put both in your pocket. That’s what the TORRAS MiniMag is for, and it does it well: it’s slim, the magnet holds firmly, and there’s no cable to deal with.
Just don’t expect speed. Over the magnet, an iPhone charges at 7.5W, and that’s slow.

One-sentence verdict: Buy it if you want a slim magnetic battery that snaps on for cable-free top-ups and goes in your pocket with the phone; skip it if you need fast charging or want to get the most out of every mAh.
Genuinely slim, snaps on for cable-free top-ups — wireless charging is the slow part.

It’s a thin slab with a magnet ring on one face and a USB-C port on the edge. And it really is slim: the phone doesn’t turn into a brick, and TORRAS’s claim that it won’t stick out past the bottom of the case holds up.
The magnet grabs firmly, and the build feels solid. How warm it runs and how heavy it feels is another matter, because owner reports on both are mixed, which usually means a product sits right on the edge of what people find acceptable.
Snap it onto a MagSafe iPhone, or onto a case with a magnet ring, and it starts charging wirelessly. Plug in the included USB-C cable when you want faster wired charging or need to recharge the bank itself.
The magnet holds well, and 22.5W wired is fine.
Wireless is the weak point, and it’s the whole reason you’d buy a bank like this. You get 7.5W to an iPhone, and the conversion losses eat into the 10,000mAh, so a wireless top-up is both slow and shorter than the number on the box suggests. Heat is the wild card.

Owner feedback on how long it lasts is broadly fine, with no strong pattern of failures. TORRAS covers it with a limited warranty, and you can register for extended cover.
At $44.98, you’re paying extra for the magnet and the slim shape. A wired 10,000mAh bank like the Anker 10,000mAh 30W ($25.99) costs less and charges faster.
So the value is all about convenience: no cable, a battery that snaps straight onto the back of the phone, and something that rides in your pocket with it instead of dangling from a cord while you try to send a message. If that’s worth the premium and the slower speed to you, it’s a fair buy. If you just want capacity you can use efficiently, buy a wired bank. We’d call it a fair buy under about $38.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| TORRAS MiniMag 10,000mAh Magnetic (this bank) | A slim magnetic top-up that pockets with the phone | Genuinely slim, firm magnet, cable-free use | Slow wireless; conversion losses; ~$45 | $44.98 |
| Anker 10,000mAh 30W Power Bank | The same capacity, wired and faster | 30W, built-in cable, cheaper | Not magnetic; needs a cable to the phone | $25.99 |
| Belkin 5,000mAh 15W Qi2 MagSafe | A lighter magnetic bank with a kickstand | Built-in stand, Qi2, USB-C cable included | Half the capacity; also pricey | $59.99 |
Don’t need the magnet? A wired Anker 10K charges faster for less money. If you’d like a magnetic bank that’s lighter and has a stand, look at the Belkin 5K Qi2, though you’ll pay more per mAh.
For cable-free charging you can carry in a pocket, the MiniMag is well made and does what it promises: it’s slim enough to live on the back of your phone all afternoon, the magnet holds firmly, and you can keep scrolling, texting or taking photos while it tops the battery up.
The costs are the usual ones for a magnetic bank. You’ll feel them. Wireless charging runs at 7.5W and is slow, conversion losses mean 10,000mAh doesn’t go as far as it sounds, and owners are split on weight and heat. It also costs more than a faster wired bank. Buy it for the convenience. If you want speed and efficiency, buy wired.

Figures marked “TORRAS” are the manufacturer’s published claims. “N/A” means the value is not listed on the Amazon listing or the TORRAS product page.
About 7.5W to an iPhone. Apple caps magnetic wireless charging there, so a wireless top-up is slow.
Roughly one to two full phone charges over a cable, and fewer wirelessly because of conversion losses.
Yes. It snaps onto the back of the phone, the two still fit in a pocket together, and it doesn’t stick out past the bottom of most cases.
Owner reports are mixed. Some say it stays cool and others say it warms up quickly, so it’s borderline on heat.
Only if you stick a magnet ring on first. It’s designed for MagSafe iPhones.
It is if cable-free, snap-on convenience matters to you. If you just want capacity and speed, a wired 10K bank is faster and cheaper.
