  1. Dana

    We bought this for a trip to Baja on our dual sport motorcycles since we were going to be off the beaten path. We never needed it, but used it on a gentlemen’s dirt bike who’s battery was completely dead (in Bahia de los Angeles), it started on the first try. Everyone in his group was so impressed, they were going to purchase one when they got back to the U.S.

  2. Inyang Effiong

    Got this 2 weeks ago and after initial charge, looked around for a suitable test dummy.
    GSX-R1000 was started on first kick.

    Needed something bigger

    A 6.0L V6 GM truck!
    Crank, crank, crank, vrooooooooom.
    5 of my mates want!

  3. frank

    co-worker left his lights on all day, hooked up the pps and his car fired right up. pps still shows full charge


    To begin with the main reason I bought this device is because my son and I both Hunt a very remote mountainous area 8-miles from our Deer Camp that
    we access by way of a UTV and an ATV.
    I would never want to hike back in the dark because of a dead battery.
    I recieved this unit in just early last week and
    was happy to have it on our trips out in the remote areas we hunt this past weekend.
    What I didn’t expect was the emergency that awoke me early in the morning while asleep in my camper.
    I suffer from sleep appenia and I use what is called a C-PAP(Mini Compressor) machine for this problem, it helps me to maintain continuous breathing that I power with an automotive type 12v battery.
    Around 1:30 in the morning the car battery went
    dead and since the battery I have has 4 output post on it I got the idea to hook up the new PPS that I bought and see if it would help…
    Now I know this isn’t built to actually charge and maintain status while the battery is under a load but I was amazed at this pocket size power source it handled the job well from 1:30 am until 7am the next morning and used only 75% of the power from it.
    I would strongly recommend anyone who ventures in the remote outdoors to look at not only portability of this power supply but for what you get you can’t beat the price either.

    I’m a BMW motorcycle dealer, where can I buy these to sell in my store Disconnected several batteries on high draw bikes, the battery wizzed the over and they started. Even our 650 single went with the unit. Great product!
