    • Perfect. Have truck, will crank. Tanks! I mean, Thanks!
Style: SuperCap 2
Update #3: Have not needed to use it since last edit but it connects & loads up using any & all of the included connectors. I’ve even used my little 10w USB solar panel. (Took forever for reasons obvious). All worked & when I tested each, used the truck & it was ready to go. So no issues. Works as stated. Works well. The only variables are the vehicle & the user. Aside from a tiny solar who-cares-what-you-have-going-on-today panel, each method you use determines your charge time. It’s math. It works. Buy it. Just double check your connections like I didn’t. Wink-wink. Vanlifer tip for those with steeds & iffy electrical systems: Load it with your USB pack whenever you park. If you occasionally need a jump but think often enough you might need one every time, this practice will ensure less downtime when you have to go but ‘Damn! Three days since last jump. Trickled down to 20%, USB battery, yikes! I’ll be on the road in forty five minutes, not 2.5! Damn damn! :insert Doc Brown facial expression: So, shortly; Have a weak electrical system? Buy this & habitually connect it to your USB battery pack on parking. Less downtime. Update #2: I gave it a day. Out of frustrated fairness, I gave it another go. Connected to a charged battery this time. Used only the jumper connector to turn it on. Worked. Seems intermittent. Unsure of cause. Will continue use as needed & update review as my experience evolves. Update #1: It’s been a few short months & it no longer works. It will charge but not begin the countdown when the button is pressed. Damn waste of homeless guy funds! Original review below: The BEST thing about this is that it will crank a light truck. Others I looked at won’t work very well with even my little 4.6L motor. When I was experiencing an electrical issue, this helped me stay moving until I found the issue. It’s light, so easy to stow, carry, and retrieve out of your VEDC. Simple to use. Very few connections. It’s literally plug (or pinch) & play. & in the event you have a tragically low battery, you can even prime this thing with your cell phone charger or a portable USB battery. Takes longer but it works. One-person use with a ‘beep’ loud enough to hear inside your car if it’s freezing outside while you wait for it to charge. And it’s tough. With no battery in it, you don’t have to worry about handling it like you would a lithium ion or a lead acid battery jump starter. ... show more

I love this jump starter. A couple of cars ago, I damaged a diode in the alternator when the jumper cables were hooked up incorrectly. That was an expensive mistake. I was gifted a battery-based jump starter. That thing was heavy, bulky and needed to be charged periodically. I didn't want to drive that around in the car and have it take up space in the trunk. This jump starter is hand held, reasonably light and easy to use. I tried charging it with the cigarette lighter and with a regular cell phone USB charger in the house. The stated charging times matched mine. It's way easier to connect a jump starter than trying to get another vehicle close enough to hook up jumper cables. I have a hybrid (not plug-in) car, and I'm leery of connecting jumper cables to it. There is a chance of blowing out the electronics, which can be insanely expensive to replace. Also, it has a baby 12V battery, just for booting the computer (and lights), which then connects the high-voltage battery to run the car. When it got cold recently, the "boot" battery got so low that everything on the car was dead. No lights or anything would come on when the driver's door was opened. Of course, I couldn't start the car. I put a battery charger on it, but it flashed an error after a while. I charged up the jump starter, connected it to the posts under the hood, started the 10-beep countdown and hit the ignition button when it reached zero. The car started right up, just like that. When I checked the display on the jump starter, it indicated that it was still 96% charged, heh. It takes hardly anything to boot the computer. The high-voltage battery came online, and we were good. It took it in for service, and they replaced the battery under warranty. For those who want extra features, such as a flashlight, USB ports to charge a phone and so on, take a look at a jump starter with a (lithium) battery. If your interest is something that charges quickly and is only used for jump starting, this is the ticket. ... show more

    • Works great! Charges in 2-3min
Style: SuperCap 2
It works great! I used it a few times on a 2017 Toyota Sienna with an old, dying battery. The battery was at about 10V, which was enough to charge the supercapacitor in about 3 minutes. It started the car perfectly on the first try, and still had 89% charge left! It charges from my 2016 Honda CRV's charging port in about 2 minutes, with 14V from the alternator. It's very easy to use and beeps when it's done charging. It does a countdown before jumpstarting, which would be especially helpful if you're alone and have to activate the jumpstarter then get in the car to start it ... show more

    • Cumberson and slow to use, but it's reliable and maintenance free
Style: SuperCap 2
after using battery banks for a few years .. if you keep them full & ready they die within 2 years .. lipo batteries don't like to be kept fully charged. Had this for 2 years .. used it about 10 times, mostly helping stranded travelers .. worked every time on everything I put it on up to v8 ... not chocked once. BEST PRO: no maintenance, caps last millions of cycles and can last 40 years (if kept in cool environment) one main CON: takes a long time (5-10min) to charge from a fully topped 13v battery... the source does not matter .. it takes it's sweet time to charge. ... show more

    • Excellent product that every driver should have
Style: SuperCap 2
I purchased one of these after having bad luck with conventional lithium battery jump starters. The batteries go dead after a few weeks and if you don't constantly maintain a charge, it becomes useless in an emergency. This device takes batteries out of the equation, so you can store it in your car indefinitely and it will always work. It allows you to jump start a dead car using the car's own dead battery. The down side is it can take many minutes for the device to work and is not instantaneous like other jump starters, but I'll happily wait for 5 minutes over having a dead jump starter ... show more
