With the introduction of high-power lithium batteries, jump-starter packs have been reduced in size to the point where they can fit in your pocket. This makes them convenient to carry in your trunk, and the long battery life means you can almost forget they are there.
We look at three jump-starters in this review from three well-known manufacturers. While they will all start your car, they have differences in performance and features that we’ll explain and give you recommendations on which is right for you.
Key Things in Common of Weego 44, Noco GB40, and Antigravity XP10
All three products aim to get your car on the road again, so there will be some similarities between them all. Properties like safety features, battery technology, and charging methods are pretty standard across most types of jump-start battery packs.
Safety Features
As used on cars, lead-acid batteries can pose a safety risk if you make a mistake when disconnecting chargers or jump-start packs. Each jump-starter on the review has built-in safety features, such as a reverse polarity checker and safety on-off switches.
USB Ports
As well as jump-starters, all the products double up as power sources to charge USB devices, such as smartphones and tablets.
LED Lights
A flat battery can happen at any time, so having light to work by is useful. All of the battery packs on review have built-in LED lights.
Jump-start 12V batteries vehicles
Most cars on the road use a 12V electrical system, and the jump-start packs on review are all designed to work with 12V systems only.

Key Differences of Weego 44, Noco GB40, and Antigravity XP10
The Weego, Noco, and Antigravity all look very different, but ultimately, they all serve the same purpose – to get your car’s engine running. But what are the significant differences, and how will they affect your choice when you want to buy one?
Features and Functions
All three are supplied with short jumper cables and crocodile clips for attaching to your car’s battery. One big difference we mentioned earlier is the bypass switch provided with the Weego.
Apart from taking up more space compared to the others, the switch adds a valuable function. It enables you to bypass all the safety features and jump-start a car with a completely flat battery.
When a car battery has drained to zero volts, the jump-starter safety features may prevent it from working. This could be the difference between getting going or calling the breakdown truck if you accidentally left the lights on.
One feature missing from the Antigravity only is a battery charge indicator. This helpful feature lets you know when it’s time to charge your jump-starter, so it’s a shame it’s missing. However, the Antigravity makes up for this by including an auto power-off function, switching the unit off when not in use.
Lead-acid batteries give off explosive gas when charged, and even a tiny spark can ignite the gas. While it’s not very likely to happen, both the Weego and Noco feature spark-proof technology to prevent an explosion.
Design
All three of the jump-starters reviewed here are small, light, and compact, but there are differences worth mentioning.
The smallest is the Antigravity, being an ultrathin 1.25 inches thick and weighing in at a featherlight one pound.
Not far behind is the Weego, only slightly wider at 1.5 inches and weighing 1.5 pounds. However, this doesn’t take into account the battery connector attachment that includes the bypass switch. This adds extra weight and size to the base unit, making the Weego far less compact.
Finally, we have the Noco, which continues with the brand’s design focus and looks solid and sturdy. It is instantly recognizable as a Noco product.
Connecting the jump-starter to a car battery is the same on all three products, using large, strong crocodile clips. But as we mentioned earlier, the Weego uses an additional part between the car battery and the jump-starter. Inside the other part are the safety features, such as the reverse polarity checker, overheat protection, and anti-spark protection.
Supported Vehicles
Despite having the lowest peak current specification at just 650 amps, the Antigravity claims to be able to start all gas engines and diesel up to 7.3 liters. That is a big claim, considering the Noco has a peak current of 1000 amps, and they only claim up to 6-liter gas and 3-liter diesel.
The much more powerful Weego, with a peak of 2100 amps current, claims to start gas engines up to 7 liters and diesel up to 3.5 liters.
Let us put those figures in perspective a little. At 650 peak amps, the Antigravity will start large engines, but you will get just a few attempts before the jump-starter battery is flat. The Noco, with a 1000-amp peak, claims up to 20 tries before it needs to be recharged.
The bottom line is to consider your vehicle’s engine size and buy the appropriate jump-starter. If your vehicle engine is large, consider the Noco or Weego over the Antigravity.
Additional Features
All three battery packs have built-in lights for working at night. The Antigravity and Noco have 110, and 100 lumens LED lights, respectively. But the Weego trumps them both with a 500 lumen LED light.
However, don’t get too excited, as a 100 lumen LED is equivalent to a 15-watt bulb, while 500 lumens is around 45 watts, so none are very bright.
Warranty
Both the Noco and Antigravity come with a standard one-year warranty. Only the Weego has longer with a full two years.

FAQs
Can these jump-starters be used on all battery types?
The simple answer is yes. You can use them on all types of lead-acid batteries you find on cars. This includes wet, gel maintenance-free, AGM, and flooded batteries. The only thing to check is the voltage, as all three will only work on 12V batteries.
Can these products charge a battery?
The three products reviewed cannot charge your battery. They are only designed to jump-start your car when the battery is flat.
How long will the jump-starters hold their charge?
If the jump-starters are stored in cool, dry conditions, free from extreme temperature variations, they should only lose around 25% of their charge over a year. Manufacturers recommend charging the units every six months if you don’t use them.
How do I charge my jump-starter?
Methods vary, but the most common is via a mains wall socket or a USB charger.
How long will it take to charge a jump-starter?
This depends on the capacity of the jump-starter and the amperage of the charger. However, the majority will generally be fully charged after two to three hours. Check the user manual for details.
Can I use a jump-starter on my Tesla electric vehicle?
You can use the jump-starter to activate your Tesla’s electronic systems or put the car into tow mode. You cannot use it in place of the primary drive batteries.
