WHY FERRO
Not all power banks are built for the real world
Most power banks are fragile, single-port and useless once they're empty. Here's what we do differently.

Power up to 3 devices at once
Fast USB-C (up to 20W), USB-A and a Qi wireless pad. Top up your phone, earbuds and watch together, with no fighting over a single port.

Keeps going when the grid doesn't
The built-in solar panel trickle-charges in direct sunlight, so you still have emergency power on day three of a camping trip or a storm outage.

Drops, dust and rain? No problem.
Shock-absorbing rubber bumpers, a dustproof shell and IPX4 splash resistance. Toss it in a pack, a glovebox or a beach bag.

Flashlight, compass and carabiner built in
Clip it anywhere and you've got light and direction when you need them most. At 37Wh it's also cleared for carry-on bags.
READY FOR ANYTHING
One power bank. Every situation.



HOW IT WORKS
Ready in 3 simple steps
Charge it up
Plug in via USB-C for a fast full charge, or leave it in the sun for a backup top-up.
Clip it on
Hook it to your bag, belt loop or tent with the carabiner. It goes wherever you go.
Power anything
Charge by cable or just set your phone on the wireless pad. Up to 3 devices at once.

Frequently asked questions
Will it work with my phone?
Yes. The USB-C and USB-A ports work with iPhone, Samsung, Pixel and most phones, tablets, earbuds and watches (use your device's cable). The wireless pad works with any Qi-compatible phone, including iPhone 8 and newer.
Can I take it on a plane?
Yes. At 37Wh, Ferro is well under the 100Wh carry-on limit set by the TSA and most airlines. Power banks must go in your carry-on, not checked luggage.
How does the solar panel work?
It slowly tops up the battery in direct sunlight, giving you backup power when there's no outlet. It's designed for emergencies and trickle charging; for a full recharge, plug in via USB-C.
How many phone charges do I get?
Roughly 2 to 2.5 full charges for most modern smartphones, depending on the model and battery size.
Which bundle should I choose?
2 Power Banks is our most popular pick: one for your bag and one for the car or emergency kit. 3 Power Banks gives you the lowest price per unit and makes a great gift.
