Sharmeal Jump Starter 6000A, 12V Car Battery Jump Starter with USB Quick Charge (Up to All Gas or 10.0L Diesel Engine), Battery Booster with 3 Modes Flashlight and Jumper Cable

This seriously takes fooooorrrrreeeeevvvvvveeeeerrrrrr to charge, but I am shocked at its performance! I see several reviews stating they got a defective product because it won't charge... I'm betting most of them just didn't wait long enough. Keep in mind, you are charging a device with enough power to jump start a V6, with a teeeeeny tiny little USB cord! Even after reading reviews, I still thought it was taking too long. Seriously, you just need to wait. Mine arrived at 78% and took about an hour to tick up to 79%. Then it stayed there for several hours and I was losing hope, but I decided to leave it overnight based on some of the reviews I read. I looked at it maybe 20 minutes later and it was up to 94%. Then it jumped up to 100% after maybe another 20 minutes or so. It seems like the gauge may just take some time to catch up. I ordered this after I broke my Jeep and the battery died because it ended up sitting longer than I anticipated. I chose this one because it was the only one under $200 that I could get same day. It arrived fast, but I was honestly so nervous this wasn't going to work that I ended up putting it off for days because I just didn't want to deal with returning it and finding something else. I finally decided it was time to stop procrastinating, and I was absolutely shocked that my Jeep fired right up! After jump starting, the battery still reads 100%. This is what makes me think maybe the gauge isn't super accurate. Some reviews state that it only works a few times. Even if that's true, this is still 100% worth the purchase! Other reviews have claimed it's still going strong after many uses, so it's probably a toss-up, or maybe it depends on the vehicle you're jump starting. I plan to purchase another one to have on hand, in case the first one fails. I love that this is small, lightweight, and won't take up a ton of space in my already cramped overlanding setup. I was nervous because the instructions were a little weird (bad translation to English), but it was pretty simple to use. The case is a little crooked, but it's functional and keeps everything together and protected.

An excellent jump starter that's rescued multiple vehicles, but be aware that it is only good if the voltage on the car is 10 volts or higher. Below that, the starter cannot compensate for the voltage drop. I also found that it does not have enough energy to jump a car when the Jump Starter itself is below 80%, which is about 3 or 4 jumps. Charging is simple via USB-C, drawing up to 15 watts, but it has no problem charging from a 10-watt (2-amp) charger. The case is sturdy, with everything neatly and comfortably fitting inside, so even if you are in a hurry, it's tolerant of "messy" packing. The only "con" I can think of is the jumper adapter itself. It's a bit awkward to have a large block off the end of the charger. I do like that it does give you a reversed polarity warning with warning lights and an audible tone.

Convenient size, carrying case fits under the rear side of the front seats. Bought solely for battery jump in case of emergencies. Came 2/3 charged, charged to full before putting in the car. I needed to use it within the first month, jumped the car with no issues and immediately justified the purchase. Still kept in car, haven't noticed a loss in charge, but will continue to check regularly. Would recommend

Great! Strong jump. Started my diesel pickup without a problem. Had 90% battery left. Also started big mower. Works perfectly 👌

I purchased one of these after using a friends at work to jump my truck. the few times I have used it, it worked just fine. I was skeptical how something so small could turn over my truck engine, but it certainly did. I also carry it in my dry box as a back up starter for my surface drive engine that has a bad stator which does not re-charge the battery while running. It's also great when when any lawn equipment has a dead battery and you don't need to pull out huge old style jump packs or run extension cords out to ac powered jumper/chargers. If the longevity ends up being good, I will be very happy. the only reason I removed one star is because the cables are so so short. Yes I was able to get them on the battery, but you literally need to stretch them apart to maximum length to clamp on the posts. I wish the cables were just a few inches longer and it would be perfect. the charging function is easy to see and the battery level also. We will see how long the battery life lasts as batteries that tend to sit without cycling never seem to last more than a few years. And truthfully, it's not like you use an item like this more than a couple times per year.

It works great. Easy to use. My mercedes is usually hard to start but this jumped it easy turn on with the car battery being dead

This got me through a dead battery enough to get to the auto store, so it looks like it works! Easy to use, just clip on the clamps and start your car. Takes a while to charge, but the number of jump starts you get out of it is well worth the time. The price was right, so I can't complain. The flashlight feature isn't something I really want to use all that often, but it's nice to know that it's there. Small enough to remain in the car even when you're not using it.

It's powerful enough to start my van on ice cold mornings. Easy to use, using it frees the time that I would normally pull the big charger out. Always keep in glovebox, goes where I go. Very portable the safety features is a blessing. Never hooked up wrong charging is a little slow. But well worth it. Storing power is something I like. Always charged and ready for the next thing I need jumped
