Jump-N-Carry JNC550A 1100 Peak Amp Jump Starter with Air Compressor , Black

Easy to use and holds its charge well. Nephew has an older car and bad habit of draining the battery while his phone charged or had the radio on. Keeps this in the trunk and gets him back up and going. Well made and solid.

Great charger everything function perfect came with a charge even.

Definitely worth the investment. Works great at jumping my car battery. Takes a while to fully charge when used a lot. The air pump takes a little longer than I like to fill tires though. Overall a great item to have around.

This is a good battery, a few tweaks could have made it a great one. As far as the primary function as a jump box, I have zero complaints. I use it to jumpstart my mower and it has performed every time. I was looking for a battery that was not lithium because I did not want a spontaneous trunk fire; this fit the bill. The reason for 4 stars is the weak and very loud air pump (but that is not why I bought this so it will probably never be used). Also, cable management could be better - there is a strange way that the +/- cables wrap around the sides of the box and the clamps tuck into a pocket - this takes a bit of work. Also, the 120v and 12v charging cables are just loose with no onboard storage - I hope I can find them when I need them. Also, the documentation is lacking quiet a bit, just know that to turn the light on you have to hold the switch for 2-3 seconds.

Like all JNC products, this is the gold standard. Plenty of starting power. Only "complaint" is the weight....too heavy for my wife to use, so I bought her a lithium jumper that weighs about a pound! Also, you will eventually trip he heat safety on the air compressor if you try to blow up a flat 20" truck tire! Also, I like the safety features on this one; I wish my JNC 660 had them.

I have had this since 2022 only used it one time, the display has said: ER 3But apparently means dead battery to the point where it can't be recharged. Every time I've gone to use this there was barely enough power to start it but always had to be put on a charger for at least 24 hours and now it won't even charge at all. So it looks like it's going to need to do battery which is not going to be worth replacing since it costs as much as the unit. I think the concept is great and all in one emergency kit if you will but the battery situation needs to be looked at. Definitely would not buy this again.

Long lasting powerful battery. Quality cables/connectors with sufficient length for use. Air compressor works quickly without overheating, and LED light is adequate for working at night. The display provides voltage of battery prior to turning on the jumpstarter, as well as the voltage stored combined with the battery. Convenient USB port for electronics charging, as well as a 12V plug for auto accessories.

I've had a number of jump boxes with air compressors in them over the years. And they have all held up very well. But they definitely needed to be charged every few months. So I scheduled a reminder to do so. I purchased this one in October 2023 and have used it any number of times (the compressor more than the jumper) and it holds an incredible charge. I just spent the past two weeks with a tire going flat and I used it almost every day to top the tire off. The compressor had to run at least 4-5 minutes a shot. After I got a new tire, I thought, "well, this will need to be charged". So I took it in the house and after about 15 seconds, it registered "full". IT DIDN'T NEED A CHARGE. That's amazing. This is hands down the best jumper box I've ever owned. HIGHLY RECOMMEND.
