VicTsing 1000A Peak 20800mAh Portable Car Jump Starter (Up to 8.0L Gas, 6.0L Diesel Engine), 12V Auto Battery Booster, Compact Power Pack with QC3.0 Output, Built-in Compass and LED Light

I used this jump starter twice in the same day on the same vehicle. It was a Honda HR-V. The battery was dead, so I gave this thing a shot. After hooking it up, it took about a minute before the car would start, but it worked great. I took a look at how much power was left in the jump starter and it went from 100 percent down to 99 percent. I used it again the same day and it worked great again and the remaining charge went from 99 percent down to 98 percent. Apparently, you can use this thing a number of times before the batter is discharged to the point where it will not work. Prior to using it for the first time, it sat in my trunk for a couple of months and it was still at a 100 percent charge when I needed it, so it does hold a charge very well. I really like it. It's small and compact and does a great job. Don't leave home without it.

I used it for the first time a little more than 30 days after buying it and when I did I needed the boost button but it wouldn't press down so I had to use a pen to try to press it and it broke so I didn't get one singal successful use out of this but bc it's not something you need daily and I didn't within 30 days I can no longer return it ***UPDATE*** After writing that the company contacted me to fix the issue. They sent me another however the buttons were the same as the first one and the power button got semi stuck on the first press indicating that it was going to probably break again but the I noticed the buttons looked different in the photo on Amazon so I requested that version which I learned was an old style but the company sent it and it is 💯% better button wise and although I haven't needed to use it I can tell the power button and flashlight button won't break or get stuck like the previous two however I do have concerns about the boost button if needed bc it is the same. So my update in wanting to put 0 stars to putting 4 stars is basically 2 stars for customer service which was great after they contacted me bc I couldn't contact them initially and 2 stars for the older version of this device.

This was one of my wife's Christmas presents,She has a Dodge Sprinter diesel.The heater is unreplaceable so on cold mornings the battery goes low trying to start it.Today I used the unite for the first time...Hooked it up lights came on,told wife to "wind it up" turned over quick and started!! Yeah,thank you

Finally had use for this battery, and the very first time the on/off button stuck below the plastic case. I can't seem to pick it out, or move it over. It did actually work jumping the car, but certainly not worth what I paid for a total of one use. Very disappointed.

Used it to start Ford Focus with completely dead battery (it didn't have power for the interior lights) and the car started on the 1st try and used only 3% of the 100% charge.I'll update as I continue using it, but so far great product.

This is the best gift my wife has ever gotten me. It came at at 92% charge. I have used it several days now and it works like a dream. My battery is completely dead in the morning...just connect the cables and turn the key...BANG, it turns right over!!!This is a must have for cars, SUVS and pick-up trucks. 5 stars in every way.

I haven't yet had cause to test the jump start function, but the battery charges correctly, seems to hold a charge, and worked to charge my phone.

I bought this as I knew a used truck I had recently purchased had an older battery. I didn’t want to get stuck and not have another car around to jump it. Although the truck battery died in my garage and I was at home where I could’ve jumped it with my car- this tool worked like a charm! I have bought 3 so far as gifts!
