Sharmeal Car Jump Starter 5000A, Jump Starter Battery Pack for 10.0L Gas and 9.0L Diesel, 12V Portable Jump Box with LED Light

I don't normally do "reviews". However, this thing is amazing. We have a slow draining battery, if we don't drive the car for a couple days the battery is dead when we try to start it. Didn't want to spend hundreds (or more) to figure out what the problem is so we bought this. It hooks right up and the car starts instantly, even if the battery is so dead the interior lights don't come on. It's worked every time, and you can get about 10-20 jumps with a full charge. Seriously one of the best car accessories I have ever bought. Highly recommended.

When I went to my car Saturday morning for work, my car was dead. No warning or anything from the night before. My husband said I was wasting money buying this and it wouldn't work. Ordered this and got it Sat night. On Sunday morning, took this to my car, hooked it up and within 5 seconds my car started!!!! Very compact in a very nice case with a charging cord. You don't even need to read the instructions it's so easy to hook up. Very lightweight with a compass and emergency lights on it. This was a lifesaver!!!

This jump box works very well. Strong enough to jump my 5.7 tundra and only use 20% per jump battery. I would recommend this product and it very user friendly for beginners

Perfect small jump starter. Everyone should have as an accessory in their car. Works well, holds charge.

Well this thing is pretty cool, but it wont start a f450. It killed battery pack with one turn over. Its starts the cars pretty good but thats it. Still worth the money

Nice little jump starter, easy to use and does the job. I don't drive my 2003 Ranger much and the battery wasn't starting it due to that, so I had to use this jumper 2 different times and figured I needed a new battery, but found out it was just drained from not running the Ranger, so they gave it a deep charge and it's been good so far. The battery is a couple years old.

I purchased this battery jumper to replace one I had bought like 10 years ago. I have had to use it several times since purchase. It is easy to use after charging. Jumped my rider and also my crown Victoria. Had no issues with the jumper. It’s compact size fits in glove box for any emergency starting needed.

Overall: this is a good size, with a decent case usable flashlight that was able to start a 1979 F-100 with a 302 (5.0L) V8 with the battery completely disconnected. More modern cars have more computers and have a higher electric requirement to start but this still seems impressive that it started the V8 with zero assistance from the truck battery. Pros: its pretty compact coming in at a little under 3.5 x 7.5 x 1.5 inches for just the jump pack, and 5 x 8.5 x 3.5 inches for the case. It does include a USB A to USB C cord for charging the unit and using the unit to charge other devices. I have not tried to use this on a modern vehicle but like I said it started my 79 ford with a carbureted 302 V8 when hooked directly to the terminals. The flashlight seems like it is actually bright enough to be useful, probably around 100-200 lumens. The model I received has a button on the jumper cable plug in for using when the battery is completely dead or removed. My understanding is that most have this but not all so I am counting it as a pro. The biggest pro for me is the price. I paid $29.98 or something close to it for this and decided to double down and get 2 for just under $64 with tax. These are usually $100+ at local box stores so if I can get 2-3 uses of helping other people or myself with this, it will be worth every penny. Cons: So far the only real con that I have is that it is picky about what AC/wall adapter you use to charge the jump pack. Other pictures of the back of the jump pack didnt have as much writing as the ones I received so I wanted to share it does say the input needs to be 2A (amps). It works just fine with 1A chargers, but you cant go over 2A or the safety prevents it from charging. I tried using my normal cell phone fast charger and it would not do anything so make sure you have a non-fast charging wall adapter to charge this with. This is kind of a mild nuisance so im only give 4 stars for this reason but this should not stop you from buying it. I also imagine the people saying theirs would not charge were only using fast chargers over the 2A limit.
