The NEXPOW 2000A is an excellent option to consider when looking for jump starters within a budget. I bought this jump starter for under $100 on Amazon.
It is not my first time testing a jump starter from NEXPOW. I bought and tested many of the best jump starters from NEXPOW, including the NEXPOW 1500A.
My first impressions of this NEXPOW 2000A jump starter are solid.
NEXPOW 2000A Build Quality and Ports selection
This NEXPOW 2000A jump starter is just a little bit bigger than an average-sized human hand. It measures 9 inches by 3.4 inches with a thickness of 1.2 inches and weighs around a pound and a half.
This makes it super portable, and you can store it in your car without taking up much space.
The build quality has stayed the same as other NEXPOW models, which is a good thing, as I had no issues with the previous model from NEXPOW.
The same goes for the DC out jack and USB ports. This jump starter keeps a decent selection of input and output ports from its predecessor.
It has 2 USB-A ports and one of which is compatible with QuickCharge. It means you should not have any problem powering and charging any smartphone, tablet, or other compatible devices with this jump starter.
It also has a USB-C port for charging the jump starter pack. You can also use this USB-C port to power other compatible devices like smartphones and tablets.
Unfortunately, I did not see any power delivery standard on the USB-C port. In my testing, this port only provided 2 amps of charging current no matter what device I connected.
There is also a DC out port on this NEXPOW 2000A jump starter, which you can use to power other 12V accessories using a cigarette lighter adapter. Just make sure you do not use devices that have a high current draw.
The clamps on this NEXPOW 2000A jump starter are solid, and I have no complaints regarding their durability.
The inside of the clamps is metal with plastic covering the outside to protect from accidental shorts. The jumper clamps have a strong clamping force, which helps make a good connection with the battery.
The cables are durable and long enough so you can rest the jump starter easily on the vehicle.
I also tested the connector, which connects the jumper cables to the jump starter, and found it to be reliable. The connection it makes is secure. I do not think that this connector will come loose anytime soon.
NEXPOW 2000A Safety Features
When it comes to the NEXPOW2000A safety features, this jump starter checks all the boxes on my list. It has short-circuited and reverse-polarity protection features.
The warnings are loud, and the jump starter does not supply any power to the vehicle until you correct the clamps to the battery.
It means that even your grandma can use this jump starter on her car, and nothing terrible should happen.
Charging this NEXPOW 2000A jump starter is pretty straightforward. Unlike the previous model, the wall charger comes included in the box.
In my testing, it took around 8 hours to fully charge this jump starter, with the included wall adapter from a completely dead state.
I would rate this as an improvement in the charging time when compared to the older model. The previous model took more than 12 hours to get fully charged.
It might be due to the small battery size of 18,000 mAh of this new jump starter when compared to the 21,800 mAh capacity of the older NEXPOW 1500A.
In the real world, I have not noticed a big difference in performance. In my testing, this jump starter provides a similar number of jump starts to the previous model. But, it has more cranking amps than its predecessor.
What comes in the box of the NEXPOW 2000A?
In the box, this jump starter comes with a USB-C to USB-A cable, a wall adapter, a nice hard-shell carrying case, and a bad NEXPOW 2000A user manual. Just throw that user manual away. It sucks
Storing this jump starter is not a problem. You can use the hard-shell case to keep everything together. This way, it will not make a rattling noise in your glove compartment, and you will have everything when you need to jump-start your vehicle.
To test this NEXPOW 2000A jump starter, I connected a known weak battery to my SUV. I did this to simulate a weak battery on a test vehicle.
I had no trouble jump-starting a medium-sized SUV with a 4.6L gasoline engine with this jump starter.
I turned off the vehicle and gave it another go. To my surprise, the jump starter was not helping to spin the starter motor.
I looked at the jumper clamps and found an error indicating that the jump starter has overheated. I have never seen such a warning on the previous jump-starters from NEXPOW. I looked it up on the internet and found this to be perfectly normal.
I gave this jump starter a few minutes and then tried to jump-start the vehicle with a 4.6L gasoline engine, and it started right on the first key turn.
I continued my testing by using this jump-starter from Nexpow to start a 2006 Ford truck with a 4.2L V6 engine, and it had no problem starting that too.
Extreme Testing the NEXPOW 2000A
I also tested this jump starter by doing my famous freezer torture test.
What I am about to show you is very dangerous, so do not attempt to do this at home or with your jump starter. Repeating this can damage your electronics and even cause injuries. I am doing this kind of test because I am an adult, and I love doing it.
Seriously, do not put any electronics in freezers or ovens. I did this, so you don’t have to.
I put this jump starter in the freezer compartment of my refrigerator for more than 30 minutes. I did this to simulate an extreme cold situation for the lithium battery inside.
I tested this “cold” NEXPOW 2000A jump starter on the same SUV, with the same weak battery. To my surprise, this jump starter started the vehicle just fine. I had no problem whatsoever. And this time around, the jump starter did not display any overheat warnings.
This jump-starter passed my freezer torture test, which means that it should work fine in cold climates too.
Testing on Diesel Engines
The real struggle for this jump starter came when I tried to start large diesel engines (5L or more) with dead batteries.
Sure, this jump starter can start a diesel engine with a weak battery. But when it comes to jump-starting a diesel engine with a dead battery, this jump starter does not have enough juice to do it. Even when fully charged.
It raises a question. Maybe, the advertised 2000 Amps is just a lie? Well, these are 2000 “peak cranking amps.” The real cranking amps are way lower. Usually, the real cranking amps are somewhere close to 30 to 40% of the advertised peak cranking amps number.
I tested this on a 4L diesel engine with a weak battery, and this jump starter worked flawlessly.
Anything huge, this jump-starter had to struggle a lot, and the overheating of this jump-starter made the jump-starting process too slow. You have to wait for the jump starter to cool down before trying to start your vehicle again.
NEXPOW 2000A Testing Data: Real Cranking Amps
I took the readings from my clamp-meter and made this easy-to-understand chart showing how much cranking amps this jump starter provides.
Here in this chart, you can see the two lines showing how many real-world cranking amps this jump-starter from Nexpow was able to deliver.
In the case of the gasoline engine, it delivered around 550 cranking amps. But when I tested it with a diesel engine, it put out nearly 700 cranking amps. But this stress caused it to heat a lot, and the jump-starter needed almost 10 minutes to cool down before it providing another jump-start.
I do not think this jump starter is best for starting diesel engines over 3.5L. I have seen some people on Amazon and other forums who reported that their NEXPOW 2000A got so hot that it started smoking.
If you want to use it on a gasoline engine, you should be good to go with this jump-starter.
Charge Holding Capabilities
Charge holding capabilities of this NEXPOW 2000A jump starter is also good.
I used this jump starter after it was sitting in my glove box for about 4 months and it worked fine. It still showed 50% battery on the indicator LEDs, which meant it was good to go for almost two more jump-starts.
I would recommend you charge this jump starter every three months to make sure you are ready for those unexpected times.
My Only Complaint
My only complaint with this NEXPOW 2000a jump starter is that this does not offer a manual mode. This means that the jump starter will not work on vehicles with a complete dead/empty battery.
This jump-starter needs at least 2 volts coming from the battery to work. I am not going to make this affect my purchasing decision, though. I have seen many jump-starters that cost a lot more than this and perform poorly.
NEXPOW 2000A Overview
I think NEXPOW 2000A is a solid choice for anyone looking for a budget-friendly option. It has excellent power, portability, and all the features that you are ever going to need from a jump-starter. At its price, this jump-starter is hard to beat.
