How it works

Three moves, no cable.

Step 01

Snap the pack on

The magnet ring pulls the pack onto the charging coil of the phone, so it lines up every time. It works on iPhone models with built-in magnets, or on any case with a magnetic ring.

Step 02

Keep using the phone

The pack charges at 5, 7.5, 10 or 15 W, depending on the phone and its temperature. Need it faster? Plug in a USB-C cable for up to 20 W.

Step 03

Take it off

At 20% on your desk, the pack comes off and goes in a bag. The phone stays thin for the rest of the day.

The honest part

Magnetic is convenient. It is not more efficient.

A snap-on pack loses the same energy across the coil as an integrated case. What you buy is optionality: thin on normal days, more power on long ones.

If you want power that is always on the phone, the Slim 3600 battery case is the simpler buy. If you only need extra power on some days, this is the line.

What we claim

15 W magnetic. Not Qi2.

The Snap packs use magnetically aligned Qi wireless charging at up to 15 W. They are not Qi2 certified, so the Qi2 mark does not appear on the product, the box or our listings.

Two words we never use

Apple's magnetic charging trademark and its "made for" programme names do not appear anywhere in our catalogue. Our magnetic products are compatible with the Qi standard and are described as magnetically aligned — nothing more.
