Our take on the Ultra-Thin 20W Magnetic Wireless Power Bank for iPhone Slim MagSafe Battery Pack

A slim MagSafe-style battery pack that snaps onto the back of an iPhone and charges wirelessly at up to 20W, with a USB-C port for wired charging and a Lightning input option. It measures 68x9x104 mm and weighs 145 grams, so it adds little bulk to a pocket. The body is silicone over aluminum alloy, and it is TSA-approved for carry-on. The best new price is $49.99 at BlueBolt Chargers as of November 7, 2026, the only new price listed.

Pros
  • Magnetic attachment aligns the coil without clips
  • 20W wireless output is fast for a pack this thin
  • 9 mm thick and 145 grams, barely noticeable on a phone
  • USB-C port for wired charging and a Lightning input option
  • Silicone and aluminum build feels more solid than plastic packs
  • TSA-approved for carry-on
Cons
  • Only one new price listed, so there is little to compare
  • No wall adapter in the box, cable only
  • Wireless charging wastes power, so real capacity is below the rated figure
  • Magnetic hold depends on a MagSafe case or a bare iPhone

Questions and answers

Will it charge through a phone case?
It works with MagSafe-compatible cases. Thick or non-magnetic cases weaken the hold and slow charging.
How many times can it charge an iPhone?
Expect roughly one full charge, less if you charge wirelessly, since wireless transfer loses energy as heat.
Does it come with a wall charger?
No. It ships with a USB-C cable only, so you need your own adapter.
Can it charge Android phones?
Yes, over the USB-C port. Magnetic alignment is designed for iPhone, so Android phones need a magnetic case or a cable.
Is it allowed on a plane?
Yes. It is TSA-approved and its size is well under the carry-on battery limit.
When is the price lowest?
Only one new price is listed, $49.99 at BlueBolt Chargers as of November 7, 2026, so there is no recent range to time a drop against.
Where is the Ultra-Thin 20W Magnetic Wireless Power Bank for iPhone Slim MagSafe Battery Pack cheapest?
