Car Jump Starter Portable Battery Station

We have a Dodge Ram with a Cummins 6.7L turbo diesel engine. Because of Covid 19, the truck has regularly sat for weeks at a time and its had a flat battery twice. Due to the location where the truck is parked, its not easy to get a battery charger out to it, so we bought this jump device. Upon delivery, went out to the truck, hooked up the cables, and the jump device turned over our 6.7L engine and the truck started immediately. We're impressed, we usually have to drag out our second car and jump from that. And, you charge the device via USB! No more losing proprietary wall chargers - which we've done twice with other units. Overall, awesome device.

I drive an 18-year-old Lexus LS-430 V-8 and tested the jumper right out of the box with a 75% charge on it. Before attempting to start, I disconnected my car battery to see if it would start without any help. Happy to report I started it five consecutive times and decided it was plenty enough for me. I’m sure I could’ve started it more because it still Showed a charge. I will charge it to 100% and leave it in the glove box for emergencies. Before I bought this I jump starter I had Red Fuel SL161 and it was not sufficient at all. It would not start my engine once if the battery was dead. It only had 400 amps peak and 200 cold cranking amps. That’s why I bought this higher powered jump starter and tested it out before assuming it would work when really needed By the way I noticed one review someone mentioned it not having a boost button to start a dead battery. I like the fact that you do not have to push any buttons. It started mine five times consecutive without hitting any buttons at all and no help from my OEM battery. Comes with high quality carry case. 100% Satisfied

I have had it less than a week but I have been trying to run it through its paces. It only got my phone to 97% charge and not 100%. I don't mind that too much. I have not jumped a car battery yet but it looks promising. Light is good enough. It's bright but not like a dedicated flashlight. This checks all the boxes that I was hoping for. It jumps car batteries, charges my phone with QuickCharge 3, charges via usb-c, emergency flashlight, small form factor, great price, included storage case.

I like the small size and weight of the CAR JUMP STARTER. It charges through a USB CABLE. I used it to jump start an engine in an older car with low battery. It worked as advertised. It also powered several phone and tablets on the same full charge. The battery pack in addition to providing a jump start also has a built in flashlight. There are USB and 12v ports to charge or power other devices. There is an On/Off Switch. However there is an additional indicator light on the jumper cables to let you know when they are plugged into the unit. One thing I really liked is the size of the jumper clamps. They open wide. I had no problem putting them on the larger battery terminals of the older antique automobile.

First time with a unit like this so obviously I was very sceptical...camping in the woods in northern Minnesota for deer hunting 10 miles from the nearest town so thought I should get one...thank God I did...used this product 3 times in 6 days..what a life saver!!! After three jump starts battery life was still showing 3 out of 4 bars so who knows how many jumps I'll get out of it. It says you can charge it from a cigarette lighter but they don't send you everything you'll need to do that but to me it's definetly worth the investment. I'm ordering one for each of my kids and my girlfriend for Xmas. Very impressed!!!

Nice and small and light compared to other jump starter. Perfect for me to use on my boat.

The first thing that caught me was the large amount of satisfied reviews. Then I noticed the sharp styling and that got me to start researching the product. I found that it has a huge number of satisfied customers and has much more starting power than most other offerings. So I decided to buy it. Very well satisfied so far. I love the features, the power, the styling, the handy carrying case. It's easy to use and has lots of power. I think it's going to be a big addition to my emergency kit in the car and having it there will give me a lot of security in case of problems on the road.

Overall, I am very happy with this purchase and anticipating this jump starter to perform as expected when needed. Now I don’t need to worry my car will have battery issue again.

Nexpow's customer service is really great and this Portable Car Jump Starter is a thing of beauty. Charges from 0% to 100% in about 6h and has enough power to crank big ol' Dodge pickup trucks without breaking a sweat. Highly recommended product!

I purchased this for my wife's new car. I have one of the bigger jump boxes in our other car. It turned out when this arrived I was having battery problems with my boat and needed to jump it. So I took both (this tiny power bank and my jump box) to hook up to both of my batteries on my boat. It fired up like I had new batteries. Then later that day a sales rep was coming to the house for something and stopped at a local restaurant. Then I received a call stating he was going to be late due to a dead batt. They let me know where he was (the restaurant about 0.25 mile from the house. So I took just this power bank to jump him. He look at me crazy when I was connecting it to his jeep. But when it fired up on the first try, he started asking questions about it and wanting to know where to get one. This little baby is packing. Now I'm ordering another to keep in my boat.

Really helpful when your battery stops working. This product basically lets you jump start your own car without another car! it's a pretty simple device, you simply charge it with a USB-C cable (included in the box!) and then you use the jumper cables that attach to this portable battery. Red goes to red, black to black and then you turn the keys and the portable battery will work it's magic. This has worked 100% of the time in my own experiences without any problems.

FANTASTIC : Instantly strongly started a Mini Cooper with a deceased battery (not merely dead discharged but drove-20-minutes->off->zero-charge deceased battery) ... Will test on big handicap van the next time I forget to drive for 3 quarantine weeks. EDIT : TESTED 13x over 3 months without recharging the jump-starter ... I did a totally unreasonable rundown test on this jump-starter WITHOUT recharging it ... I was down to 1 light on this pod and it wasn't quite as brisk of a start as at full power but it still WORKED (the van took maybe an extra 1/4 second or so to start, but then I went and got the very dead van battery replaced, so no more test)

Received the unit and it's very compact, nicely packaged, and light weight. I've been using one of the typical Jump starters that's much bigger and heavier. This is so convenient I can just store it under my back seat or even throw it in a backpack for an outing to have backup power. But the question is will it start a car? I've got a class C motorhome that's been sitting that I recently sold. It has the big Ford Triton V-10 engine. The battery was completely dead. I wondered if this would start it. Let me tell you I was amazed. I hooked it up and it started up just like it had a brand new battery. No hesitation on startup at all. After I moved it and shut it down I needed to start it again the next day. Since I hadn't charged the battery I had to jump it again. I had not recharged the battery booster but it performed exactly the same way, started right up, and the battery strength indicator is still showing full charge. Highly recommended.

This car battery jumper is small, lightweight, yet powerful. It even has a flashlight. You can choose to do it the old fashion way and wait for hours for someone to connect their car to yours for a jump. Or, you can buy this product and get moving again in seconds. It literally took 20 seconds to jump my battery. Lifesaver of a product. Every car must have this product in their trunk.

This time I buy for the second time. My friend took it away last time. He has a minivan and it is out of power. I helped him start the car. He thought it was very useful and snatched it, hahaha. So I can only buy one more. This battery has more power, which gives me more peace of mind when driving on the road!

I have already tried my car. It is very good. The emergency power supply can charge the mobile phone and the flashlight lighting function. More importantly, it is no longer afraid that the car will not start when it is empty. I think it is very necessary to buy one. The emergency power supply is on the car and is well prepared.

I've owned a couple of these over the years and this one is by far the most powerful. Overall a good product and something easy to store and use as needed. Just as a note, if your battery is truly dead, this will not start your car. It excites a surface charge on the battery and brings it up enough to crank the engine. If you've left your lights on all night and completely drained the battery, you'll need some heavy duty jumper cables and a willing friend to jump from their running car - not even the big jump boxes start a completely dead battery. I live in a climate (Tucson AZ) where batteries give no indication they are dying. Crank strong one minute, next time, nada. If we get four years out of a quality battery, we consider it excellent. So having something like this is almost an absolute in our area unless you like waiting for the AAA truck to show up.

I rarely do reviews but I really love this Jump Starter. Was skeptical before I ordered it, but the reviews are what made me purchase. So I brought a new car in feb of 2020, I was driving a jeep lareado 2004. The car has been sitting since I brought the new one. I tried to crank it a couple weeks ago and the battery was dead. I wanted to start driving the old jeep to avoid the wear and tare on my new car. So I researched car jumpers and slimed it down to the nexpow. It came quickly two days early. It wasn't fully charged when I received it, had three lights so 75%. I charged it fully in maybe an hour. Once it was fully charged I took it outside to the jeep, hooked it up there were some flashing lights then it turned solid green with some clicking noises. I tried to crank the car it almost turned over. So I unhooked the jumper read the instructions again. They really weren't clear on a couple key instructions. I figured out that in order to jump the jeep the switch must be in the off position, and secondly you must have someone there to detach the cables as soon as its started. Thats the con! I did get the car started on the the next attempt . I recommend this product, truly came in handy!!!

I bought this for the dual use capability and higher power capacity for the price. I drive an old beater car so in the cold winters here I have to get a jump start many times. This will take away the inconvenience and anxiety of waiting on someone to give me a jump. When I travel I’ll also have a backup power bank to charge my electronic devices when away from power outlets. UPDATE: The day after I received it was a very cold day and I had to jump start my car. It worked instantly on the first try. It came fully charged with four light indicators lit. Since the car started instantly it still had four power bars showing afterwards. It was simple to use and I am glad that I bought it.

Very sturdy and I like the case. Features are good lights and volt surge protector.
