Swap the battery. Keep going.

POWERSWAP is a magnetic power pack for MagSafe phones with swappable battery cartridges. When one runs out, slide in another.

Join the waitlist See how it works

Step 1

Snap it on.

Magnets hold it to the back of your MagSafe phone, so it charges while you keep using it.

Step 2

Slide out the empty cartridge.

When the battery runs low, it slides out of the bottom. No cables to untangle.

Step 3

Slide in a charged one.

Keep a spare in your pocket and you're powered up again in seconds, instead of waiting hours for a power bank to recharge.

Why swap?

A normal power bank runs out too, and then it's useless until you plug it in for hours. POWERSWAP never has to stop.

Questions.

Which phones does it work with?

Any phone that works with MagSafe. That includes most iPhones from the iPhone 12 onwards, and other phones fitted with a MagSafe-compatible magnetic case.

When can I get one?

We're aiming for early 2027. Everyone on the waitlist hears about it first, before anyone else can order.

How much charge does a cartridge give?

Each cartridge adds roughly 30% to your phone's battery. Carry a spare or two and you can keep topping up all day. This is an estimate from our prototype, and we'll confirm the final figure before launch.

Can I buy extra cartridges?

Yes. POWERSWAP comes with one cartridge, and spares are expected to cost around €25 each.

Where do you ship?

We're planning to start in Ireland. If you live somewhere else, join the waitlist anyway. It helps us decide where to ship next.
