Received the jump starter with a fully charged battery. Worked perfectly the very first time, so much easier than maneuvering another car into position and running jumper cables for an old school jump start. After two jump starts of my Honda 1.8l engine, the Nexpow's battery is still showing fully charged. The design of the unit is simple and easy to use. My only quibble is the box is almost too small to easily store the jumper clamps, so it takes some fussing to stow them in the original packaging. Better yet would be if Nexpow provided a storage bag or ½" wider or longer box.

I have bought 3 of these (1500A). One I lost, and one for each of my cars. It works GREAT. Jumps a car fast and sometimes has a 50% battery life after. With one box i’ve jumped about 13 cars and eight gas Amazon vans. Easy to connect and simple to understand. Holds a charge for a while after charging, so it can sit in your glove box and be ready to use when you need it. My dad ordered one and the flag light refused to work, but my other 3 did work. There’s a steady beam and a flashing light.

I recently purchased the NEXPOW Car Jump Starter and couldn’t be more impressed. The jump starter is compact but packs a lot of power. I love how it comes with multiple safety features The built-in LED flashlight is a nice bonus, especially for night-time emergencies. Charging it is simple, and it holds its charge for a long time, which is perfect for keeping in your car just in case. It's also lightweight and easy to store, so I don't feel like it takes up too much space in my trunk. Overall, this is a fantastic product that provides reliable power when you need it most. I highly recommend it to anyone looking for a high-quality jump starter that gets the job done!

Tired of calling family or asking random people for jumps, I searched Amazon for the latest jump starter technology. I was immediately surprised that this kind of product was readily available for $54, but optimistic after seeing multiple similar products with comparable price ranges and feedback. Out of the box it comes with a detailed instruction manual (which I appreciate), and a handy info-graphic/quick-start card which is a nice touch if you don't like reading manuals but want the gist of how to use the thing. Other reviews have noted that it comes with a charge and works out of the box, but I did fully charge it before first use. I needed it pretty much right away for a dead battery on my 2016 Honda Accord, so I clipped it on the battery terminals in two seconds according to the instructions, turned the key, and immediately my car started back to life. One note, is that when plugging the clamp cable into the battery, you do have to push quite hard to seat it in all the way, so I would make sure that it is aligned properly before doing so just to make sure nothing is damaged. For a one time jump start, the thing is worth 5 stars. The reason I gave 4, the device is for emergency use and I am cautiously suspicious about the life expectancy, beyond 1 initial jump, especially considering I will be leaving it in my trunk and that I live in Phoenix, AZ. Yes, the instructions for any type of battery are to not leave it in overly hot or cold conditions, and the Arizona sun in particular is known for draining batteries, HOWEVER, a jump-starter is not useful to me if I can't keep it with my vehicle. I will also be doing maintenance charges every 3 months as recommended by the manual. Will likely update pending further use when more time has passed.

I’ve had this thing for 5 days and I’ve already used it to jump my car twice successfully. I’m a single mom and I got an old 2010 dodge grand caravan. I replaced the battery a month ago but we got a snow storm and with the cold my battery has been dead every morning. It is so nice to be able to jump it without having to call around and find someone who can drive over and give me a jump. It’s super easy to use and takes me less than 5 minutes to get the job done. I just make sure it’s charged plug the jumper cables onto the battery. Wait for the green light on the jump starter and then power on my car. When someone else was giving me a jump it would take one or two tries to get the car to start. This thing powers in on first try. I’d recommend this to absolutely anyone since it’s inexpensive, compact, works and is easy to use.

Bought one of these last summer and it has been amazing this winter. Had issues with my car battery and this thing was able to jump start my minivan with no effort. Have had to use it multiple times now and works great. The added bonus of being able to use it as a cell phone charger is great too. Can jump start my vehicle multiple times on a single charge. Buying another one now to just leave one in each vehicle.

I’m away from home traveling, it’s the middle of winter (10 degrees) and my daughter’s car battery died leaving her stranded. She’s in high school and a fairly new driver. Over the phone after a quick conversation she plugged it in and it started her car right up. We bought this many months ago and I honestly didn’t think it would still be charged. It’s so easy to use that she was able to actually see it for the first time when she needed it and get her car running. Can’t recommend it enough.

This car jump starter is a lifesaver! It’s compact, easy to use, and has plenty of power to start my car quickly. I feel more secure knowing I have it in my car for emergencies
