    • 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

    • Some non-discussed limitations, but a great tool you can keep in your car daily
Style: SuperCap 2
TLDR; I have no reason to believe it wouldn't work for its primary intended purpose...jump starting a discharged but otherwise still healthy battery. Discussion: I bought this less than a month ago, and hoped not to need to use it for a while. But the wife's car wouldn't start abruptly last night away from the house, so I met her with this tool and a battery tester. First I followed the instructions, and it took about 3 minutes for it to fully charge. We hit the red button, and it had a ten second countdown timer (it beeps every second for that time, helpful in the dark). We tried starting the car, and the battery/super capacitor combo still didn't provide enough power to engage the starter. I re-positioned the cable clamps on the terminals to ensure a good connection, and checked the other end on the capacitor to ensure it was well connected into the super-cap (it was). Second test, same result. I hooked up the battery tester, and the test revealed a bad cell in the battery, which would explain why the super cap didn't make the expected difference. Replacing the battery fixed the problem. So what I learned is 1) if you have a battery tester (I use the Konnwei KW208, highly recommended), I'd suggest checking the battery condition before attempting to jump start with the super cap to see if you have a bad cell or other battery viability problem (especially if outside temps are at highs or lows), and 2) don't expect the super cap to be able to jump a car with a physically compromised battery (like a bad cell); a damaged battery isn't the same as a simply discharged battery. I gave the super cap high ratings because it appeared to work as designed, meaning the display kept me informed on charging status, operation processes, and ending (discharged state). It is small enough to carry on trips, and has good environmental temperature tolerances so it can be left in the car. All items advertised were included (super cap, battery cable, cigarette charger, USB cords, and carrying case) all arrived with the order in new condition, and the finish of all provided was without noticeable flaws. ... show more

This is amazing. It's really incredible. Works great and as intended. I always have it in my trunk for me or if someone needs a jump.

    • Great supplement gear but not as reliable as NOCO boost plus
Style: SuperCap 2
Got this item after reading about how great it was because needs no batteries and technology based on draw the little power left in car battery. However be forewarned won't work if your battery is completely dead or drawn down. I encountered this situation after wife left car light on and triggered alarm such that the car was burping for hours by time I got to it. With less than 0.1 amps and faint signs of life, even this Autowit couldn't suck enough life to get this capacitor filled to any substantial level even after 20 min. So might work most of time but not in all situations. At least this can be left in your car because there's no unit batteries to go bad. But I used a NOCO boost plus in reserve that saved my day. ... show more
