10,000mAh Ultra-Slim Magnetic Power Bank, 20W with LED Display

A low battery by mid-afternoon is familiar to anyone who navigates, streams and takes photos all day. This 10,000 mAh MagSafe-compatible power bank attaches to the back of your phone with magnets and charges it wirelessly, so no cable hangs off the bottom while you keep using it. Our sheet also lists wired charging, a rated maximum output of 20W and a round LED display that shows the remaining charge as a percentage. It’s brand-new and costs $79.99.

Compare our three power banks

We carry three compact packs, each with a different idea of convenience. Here’s how they line up, based on our product sheets:

Which one suits you?

Pick this one if you want a known capacity and the highest rated output of the three. The magnetic wireless power bank with kickstand makes more sense if you watch videos on the go or want to top up earbuds and a watch. The mini pocket power bank is the budget, cable-free option that plugs straight into your phone’s port.

What 10,000 mAh means in practice

Capacity is measured inside the pack, at the battery cells’ own voltage. A 10,000 mAh pack typically holds around 36 to 38 watt-hours, and some of that energy is lost as heat while charging, more so wirelessly than over a cable. The manufacturer says it can fully recharge a phone more than once; the number of full charges you actually get depends on your phone’s battery size and how you charge it.

About the 20W rating

20W is the pack’s rated maximum output. Our sheet doesn’t split that figure between magnetic and wired charging, and the speed your phone actually draws depends on the phone itself. If charging speed matters to you, ask us before you order.

Living with a slim MagSafe-compatible power bank

The magnets hold the pack on the back of a phone with MagSafe, or one in a MagSafe-compatible case, so you can keep texting or filming while it charges. The slim profile slides into a jacket pocket or bag and stays discreet when the phone is in your hand.

Phone without built-in magnets? A magnetic case or ring can give the pack something to grip, but your phone also needs to support wireless charging. If you’re not sure, ask our team.

Taking it on a flight

Canadian airline rules require power banks to travel in your carry-on, never in checked baggage. Packs under 100 Wh are generally allowed, and a 10,000 mAh pack is typically in the 36 to 38 Wh range. Rules vary by airline, so check yours before you fly. Our power bank buying guide for Canada covers the details.

Warranty and pairing ideas

It’s brand-new and sealed, with our 1-year limited warranty and 30-day returns on unused items. Add the magnetic car phone mount for road trips and your order clears $99, which means free shipping. More options are in accessories. MagSafe is a trademark of Apple Inc.; this power bank is a third-party accessory and isn’t made or endorsed by Apple.
