Q&A

Where do I wear AMPY?

Wear AMPY wherever you want! An up and down motion works best to maximize energy production. Use the accessories to strap AMPY below your knee for cycling, on your arm or leg while running, or clipped to waist when you walk. Go ahead and experiment. We’ve seen some pretty creative uses of AMPY to generate power.

What devices can AMPY charge?

Use AMPY to charge any device that has a USB 2.0, USB 3.0 or micro-USB port, including all smartphones and most wearable devices. Currently, AMPY cannot provide enough power for a laptop or tablet, but we’re working on it...

Can I plug in my phone and start charging immediately?

AMPY comes pre charged. You can charge your phone (or other USB device) on the go while moving with AMPY, or plug it in later and recharge when you get a break.

MORE Q&A

What if my AMPY isn’t charged?

With AMPY you’re never without power. In a pinch, if your phone and AMPY are both dead, you can connect AMPY to your phone, shake it for a few minutes and make a call.

How fast can it recharge my devices?

AMPY charges your devices just as fast as a wall outlet.

Can I charge AMPY from the wall?

Yes, AMPY can be charged from an AC outlet using a standard micro­USB cord.

What is the capacity of the battery inside AMPY?

AMPY contains a 1000 mAh battery, giving you enough juice to get through the day while keeping AMPY light and small.

Is AMPY waterproof?

AMPY is water resistant enough for most activities, so no worries about getting sweaty!

How much energy can I really generate?

AMPY captures your energy whenever you move and stores the power for whenever you need it. A typical day of walking can give you an extra three hours of smartphone battery life. Add a workout and generate even more. See the AMPY Energy Production infographic.

What kind of movements can charge AMPY?

AMPY is great at capturing the energy from walking, running, cycling, and other human motion. The vibrations from a moving car are probably too weak to significantly charge AMPY (unless you're driving on a REALLY bumpy road).

Can I put AMPY in my bag or briefcase and still capture energy?

If AMPY is moving with you (or your pet...) then you’re making power.

How can I get one?

Right now you can get your own AMPY only on Kickstarter at below the pre­order cost.
