SUAOKI U28 2000A Peak Jump Starter Pack, 12V Auto Battery Booster (for ALL Gas or 8.0L Diesel Engines) with USB Power Bank, LED Flashlight and Smart Battery Clamps for 12V Car & Boat, UL Certified

ok, so i'll start by saying THE SAME THING everybody else has said, "I doubted this little box will pull my big 350 on my 1999 Suburban 4x4". Notice I said "DOUBTED". I got it in when they said it would be arriving. Nobody here had jumper cables and the ones that did were scared to jump me because their cars were all small, and if they jumped me, most likely id fry their battery in the process. So, I ordered this "little box". I figured what the heck I have to lose? if it didn't work, call Amazon and they'd send a UPS man to pick it up and get a refund. I charged it the second I opened it. It didn't take long as it had arrived 75% charged already, but I didn't want NO excuses why it wouldn't work, so it was left to charge. Once charged to 100%, I went outside and followed the instructions, which honestly, common sense would tell you what needed to be done. Its truly a nobrainer. So once connected, and the green light was "a go", the moment of truth was upon me, LOL.Boom..............1st turn, and my beast was roaring. WOW!! Even my sister was outside waiting for it to fail so she could say "I told you it was a P.o.S." Even her mouth dropped. We had never used something so small to jump a vehicle, much less a full size SUV. As if this wasn't enough, the truck died out. So I had to go back and reconnect and rejump. I did this 4 times, and finally gave up and went and got my boat battery (marine grade) and put it into the truck. I figured the original battery was toast anyways because the truck had been sitting for almost 2 weeks dead. Guess what ya'll. THAT battery was discharged as well. Jumped it, and boom!! fired right up. This time, the truck idled smoothly. 5 times in under 1 hour. I checked the meter to check and see how much juice was used and left on the box.....75%. Ironic considering that's what I had left was what I started with. If you folks have ANY doubts, don't!!p.s.I also charged my iPhone 6sPlus :-)

This little jumper packs a serious wallop. I drive a sports car that requires significant power to jump due to the engine size and myriad of electrical gadgets that make it go. I discovered this the hard way when its stupidly expensive lithium ion battery system decided to act up. Most jumper boxes did not even have the power to turn on the electronics in the car let alone turn over the engine; as such, I was skeptical that this box would work, but I wanted a smaller more portable option to keep in the car. Consider me surprised, but this little box had more than enough power to start the car. But where it really surprised me was a few weeks later while visiting my parents, and my dad's F350 had a dead battery (technically batteries as its diesel engine is so large it requires two batteries). There was no way this little jumper pack would have the power to start a massive V8 engine that had been left outside in the cold overnight, but it did (in full disclosure it struggled a bit but the task was a heavy lift).

This jump starter is a beast. I've had this for 5 months and finally got the chance to use it a couple days ago. I charged it up when I first got it and it sat in the vehicle this whole time. When I went to use it the battery level was still showing 100%. My pickup battery was as dead as they get and this thing started it up better than I expected. I have a big bulky portable jump starter that won't work when my pickup battery is that dead. Neither will my non portable jump starter/charger until I charge the battery overnight. This thing fired it up like I put a brand new battery in. I was shocked and I'm still amazed. As an added bonus they take up very little room in the trunk. I will be buying another to keep in other vehicles.

It's a great jumper BUT, only used a few time and the post clamps broke? I would love to just be able to buy new clamps but can't get ahold of anyone????

I originally posted the review below years ago during a very cold winter. I'm updating my appreciation for this quality product today. It's -20 here today and my truck battery is out of commission. I took this jumper out (and probably havent' charged it in 5 months or more) and started the truck right up.This jumper has gotten me out of several jams over the years. At this stage, it's years old and has been reliable time and time again. I haven't even charged it recently that I can remember, and yet it had enough energy stored to get my vehicle going today. My thanks to the folks who designed it. Keep it up!Original:Just jumped a dead-dead-dead battery in -5 weather. The light is handy, the hookups are clean and easy. Everyone should have one of these.
