Sharmeal Jump Starter, 7000A Battery Jumper Starter Portable (All GasAll Gas/12.0L Diesel), 12V Jump Box Car Battery Jump Starter with Smart Jumper Cables, LED Light

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.

This worked great to jump start 2 dead 12 volt truck batteries. Haven't used it since, though.

Just bought it for my boat and got to use it on my mothers GMC sierra 1500 this morning and it worked perfectly. The truck wouldn’t even turn over, just the click of the starter. It fired up immediately after hooking it to the battery. The wait time was me walking to the drivers seat.

I bought this particular battery because it seemed like the best deal at the time. I say it was well worth it. I’ve been having issues with my alternator in my truck so obviously I have to jump my car each time I get in it and it’s worked at least a handful of times without having to charge it again.

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.

In the first month, this has saved me multiple times. Car battery was bad and it took a month of failures for dealer to admit it was bad. This unit got me started every day while I waited. Sometimes several times a day. Display and button not the best I've seen but once you learn it, it is simple. Very dependable. Great gift especially for women. I keep it in my car all the time.

Works good, easy to use. Bought one for each of my kids car as Christmas stocking stuffer. Great price!

WHAT POTENTIAL BUYERS SHOULD KNOW... The product arrived "AS PICTURED" but the "7000A" rating is overstated! After receiving it I looked up the actual specs on the Sharmeal website and it shows the Sharmeal M10 only has a "PEAK" rating of 4500A! It came 93% charged and may work just fine as intended but I could not justify a 5-star rating since the rating in the listing's title was falsified. I will post a picture of the true rating taken from the Sharmeal website. I like that it came in a hardshell case and included a charging brick! Both are remarkable for a jump starter at this price point. I have not used it yet so I can not vouch for the quality...but it looks like it will be easy to use and it has a LOT of safety features. There are ports that can be used to charge cell phones and other accessories and it has a nice LARGE light built in right next to the USB ports. I plan to carry it in the saddlebags of my motorcycle in the event of emergency. It won't take up much space. And who knows? Maybe I will meet someone who needs a jump start along the way...
