This is a portable power supply that has a jump starter and air compressor. It will jump start your motorcycle (or car) charge your devices and also power the rugged geek air compressor. This battery is very powerful. I have bought several of these to use and give as gifts. I’ve been carrying it on my bike for the past year. I love having it in my tent to charge my phone, watch, bluetooth helmet communicator and Garmin personal beacon.  If you would like to pick one up or look at other products they offer, you can use the promo code “advmoto” and save 20% on your order at www.RuggedGeek.com or Buy Rugged Geek Products on Amazon.
