Nexpow Jump Starter Review
Welcome to our Nexpow Jump Starter Review.
This is a budget jump box by Nexpow that’s one of the top selling models in the world right now.
We’re reviewing the 1500A version primarily, but much of what we say applies to each model in this series; we’ll give some attention to the other models too.
As recently as 4 or 5 years ago, talking about a unit that barely reaches 2lb and fits very comfortably in your hand as a 1500A jump pack would have been ridiculous! But here we are, and such a thing does exist.
How good is it really, that’s the question we’ve come to answer. Can something so small, light and inexpensive really work on cars as big as 7 Liters?
We’ll discuss that and every feature of this in full. Check out price here.
First, let’s see the basic facts and figures.

Rating the Nexpow Jump Pack
Here are the factors we liked and didn’t like about this 1500A jump starter.

The plus points:
The most important aspects are present and correct
There are a few things you need to have to make a jump starter worth having. You *need* decent jump power (obviously), you need a few key safety protections, you need clamps that are strong and well-made so that the power can actually get to the battery, you need the outer casing to be strong, and you need it to hold charge for at least some time before it gets too low to provide enough power. Now, we’ll be clear that the Nexpow doesn’t excel particularly in any of these areas. But please see the price compared to the likes of the equivelent NOCO jump pack and you’ll see why. What we are saying it, it does a good enough job in eack key aspect to be passable.
Powerful enough for medium-to-large vehicles (sometimes!)
In our analysis for this Nexpow review, it was able to jump start even 5.5L to 6L cars. That suprised us, somewhat. In our many years of testing jump starters, we’ve tended to say that you can expect a booster to *consistently* jump cars that are about half the engine size to that boasted of in the company advertising. So if the product claims to boost 10L cars, expect it to have very good results on 5L cars. Of course, this is not definitive, it also depends on a multitude of other factors; the battery CCA value (a measure of the current battery health level) and the temperature being the most important ones. Given this rough rule of thumb, we were surprised at the Nexpow’s results on cars with medium to large sized cars.
Super value
When you look at the two Pros above, together with the price, you have to say that’s excellent value. We’ve tested much poorer units at higher prices than this. This is really a good time to be a consumer in this market. LiFePO4 battery cells (which is the type used in this and all other modern lightweight jump packs) are packing more power into a smaller size with literally each year that passes; and not only that, the price is coming down each year too. That’s why you can get a decent 1500A jump starter for this price. Even 5 years ago, it would be not just impossible, but laughable to think of this possiblity.
The negative aspects:
Inconsistent results
Like most budget jump starters, results on jump starting a variety of batteries of different conditions and in vehicles of different engine sizes were inconsistent. Now, we’ll be clear. This is true of all jump starters, even the most high quality and expensive brands. But the budget models are more inconsistent, they’ll work perfectly one time and then not so well the next time, even with the same car. Normally that’s because CCA may be particularly low. This is a key area that separates budget models from higher quality ones. The NOCO models for example, work better when the battery CCA has gotten very low.
Low capacity, doesn’t hold much charge
The Nexpow is overall a decent jump pack, but this isn’t like the higher quality modern jump starters that you can leave in your car for ages, unthought of. You’ll have to keep an eye on charge if you haven’t used it for a while. Even only 2 or 3 months without attention could be long enough for power to be too low to provide enough power for your jump when you really need it. They say in their advertising material 20 jumps on a full charge. And we say that our eyebrows raised so far they almost fell off our head when we read it. We’re sure they did their calculations and its technically possible, but we advise not banking on it! You see, not every jump start is equal. A car battery with slightly low charge will need just a little power used by the jump starter. But a car battery with very low voltage will use up a lot of power for a jump. With this Nexpow jump pack, you’ll likely want to give it a charge after even one or two jumps, and after every few months of usage to be on the safe side of having enough charge in it when you really need it.

2000A Review
The Pros in common, and improvements compared to 1500A model:
rated for larger vehicle engine sizes than the 1500A model, 7.5L gas, 6.5L diesel
500A more starting power, could make the difference if your battery has low CCA (due to freezing temperatures or just the battery being in a poor state)
comes with a carrying case (the 1500A model does not)
Cons and features different to the Nexpow 1500A:
Typically 15-20% higher price for this Nexpow 2000A model

When you’re using a budget jump starter like this Nexpow 1500A model, pay particular attention to maximising the contact between the clamps and the car battery terminals.
This is nothing to do with safety; modern LiFePO4 batteries are extremely safe and jump packs from reputable makers like Nexpow come with protections like reverse polarity protection and spark-proof protection, as standard.
Rather, its about maximising your chances of a successful jump start.
Budget jump starters, as you may expect, have clamps that are not as good as the higher quality jump starters. They don’t have the precision engineering that ensures a really good connection with the battery terminals; not to the extent that the top models do anyway.
Sometimes the reason for an unsuccessful jump is not that the jump pack doesn’t have enough power, it’s that the clamps are not good enough to actually transfer the power; or, in some cases, the user did not maximise the contact.
So, when you connect the clamps, put the effort in to maximise the contact between the clamps and the terminals. Get a really solid grip onto the terminals; you want as much metal of the clamps touching metal of the terminals as possible.
This will increase the power that actually reaches the battery from the jump box.
Nexpow Jump Starter Review Summary
If we had to sum up our Nexpow Jump Starter Review, we’d say it’s a decent jump starter, which has the key features you need it to have.
Just be aware that it doesn’t have the same consistency as jump starters at the higher end of the market; that’s to be expected. For example, see this review of the Gooloo GP4000 or this Avapow 6000A review.
It doesn’t hold a ton of charge, so you’re going to need to top it up with charge from time to time, and certainly after using it once or twice for jump starts.
Here’s where to see the Nexpow 1500A price. Or see details and price for the other models below.
Good luck, driver!
