Ride insurance
This power supply saved me on a cold trip up to PA when on the way back I was a bit over-zealous with the heated gear. I got off the bike to eat, came out and the battery was dead. I hooked this up and got running right away. Glad I had it!

Must have gotten a bad one.
Was unhappy with this product. Didn't work close to as recommended. Would lose power just sitting a day or two. Would only charge my phone once before it died. Very weak and short battery life.
Bad product, but I would give Revzilla a 10 for customer service. They let me return it.

Awesome product!
I bought this simply because the battery in my Victory Vegas goes dead after sitting for a week. Lets keep in mind that I do have a GPS Tracker installed so it does draw 24/7. If the battery is dead I just hook this up and the bike fires up quicker then a regular battery installed. It packaging is small enough that I can throw it either in my Kreiga backpack and the Kreiga tailbag. I would definitely recommend to anyone who doesn't have the ability to keep their bike on a trickle charge or going on a road trip.

Peace of mind!
A week of back roads and jeep trails in NM and CO while solo convinced me to make the purchase. Did a great job of keeping my electronics charged. Did not have to use it as a supplement to jump the GS, but it was sure nice to know it was there if needed.

Used twice
This device is excellent. I have needed it to jump off two cars so far and it worked like a charm. I didn't even charge it in between.

Everyone should have 1 of these!
My husband and I both ride Harleys and over the years we have had dead batteries while traveling. We always carried jumper cables and would jump start 1 bike off the other, have to take both seats off the bikes and it's a pain! This product means only dismantling the "dead" bike and off we go!
Also, right after we bought it we had a dead battery in the car and it jump started it too! It works great and its so much simpler to use than jumper cables and another vehicle! I plan to buy 1 for each of my kids to keep in their vehicles too.

Does The Trick
Haven't had the chance to use the product to jump start a car or motorcycle, but the battery charges well itself, there is no problem using it to charge mobile devices. It's compact and travels well. One helpful hint, do not check it in your airline baggage as that is against policy, but no problem carrying it on the cabin.

I recently got stranded when my bike wouldn't start. Luckily someone had a portable Jumpstarter and helped me get home. I believe this Jumpstarter will come in handy for myself or someone else that might need their bike jumped as well.

Does the unit come with a connector that will hook up to my battery tender cable that is already on my bike, so I don't have to pull the seat off to get access to my battery??
Richard J on May 15, 2017
BEST ANSWER: No connector for tender wire. I think it's too light for current. You should be able to connect to starter wire to jump bike!! Check owners manual
How long are battery cables ... Are there any longer ones?
Pelky M on Aug 30, 2016
