Anti-Gravity AG-XP-10 18,000mAh Power Supply and Jump Starter











  • Has a High Power Capacity
  • Can jump start your charge, charge USB devices and it can even charge Laptops through its DC Ports


  • The batteries can expand if you jump start your car too quickly too many times

These days power banks can have all sorts of functions and also, they can somewhat leave the category of just being a “power bank” and go onto being a power supply. The main difference is that a power bank is usually a portable charger that has the ability to charge USB chargeable devices, while a power supply has more capabilities than just charging smartphones and tablets; as power supplies can charge laptops too and have other charging or even powering features to them. Overall, power supplies are able to be utilized in a better manner than power banks because they generally have more features that you’re able to find useful.

That is what this Anit-Gravity AG-XP-10 Power Supply is. It’s a power bank and at the same time it’s a power supply that’s able to charge your larger devices such as laptops and it can even jump start your car. Let’s see what it has an offer with each of its parts of powering capabilities.


Power Capacity:

The initial power capacity of this power bank starts at 18,000mAh and the Output power capacity that you’re actually able to use is going to depend on how you use the portable charger. That’s because there are 4 Outputs for this power supply, as it has: 2 USB Ports, 12V DC Output port, and a 19V DC Output port. We’re going to calculate the average amount of power capacity that you’re most likely going to receive from this power supply though.

Power Capacity for Smartphones

So most of the time you’re going to be able to use 13,200mAh of power capacity towards charging your devices. This is enough power to charge smartphones to max power plenty of times. As smartphones that have very low battery capacities such as the iPhone SE can charge to its full power about 8 times; then on the higher spectrum of smartphones with larger batteries such as the Galaxy S8, they can charge to full power about 4 times.

Power Capacity for Tablets

Charging tablets with this power supply is also pretty good, but if you plan on charging a tablet to its full power then it’s going to take a large chunk of the power capacity with it. Charging a Mini tablet such as the iPad Mini 2 or 4 can result in 2 full charges for them. However, charging a full-sized tablet like the iPad Air 2 can charge to its full power 1.5 times. Overall, it’s best to hold off charging tablets to their full power with this power supply if you’ve got other devices that need recharging or if you’ve gotta jump start your car.

Speaking of jump starting your car, this power supply has the ability to jump-start 7.0L Gas and Diesel engine cars about 30 times from when the power supply is at its full power capacity.

Additionally, the power supply can also charge laptops with its DC Ports and it’s basically the same experience as charging tablets because most laptops have battery capacities that are within the 4,000mAh to 5,000mAh range. So you’re able to charge a laptop twice to its full power with this AG-XP-10 power supply.

Output Charging:

USB Ports:

There are two USB ports on this power supply. One of the USB ports has a charging speed of 5V/2.0A and the other port has a charging speed of 5V/1.0A. You’re always going to want to use the 2 Amp USB port first because it gives a faster charging speed and you should only use the 1 Amp USB port for when you’re charging two devices at once. That’s because a 1 Amp charging speed is a slow speed.

DC Ports:

There are two DC Ports. One of the DC ports has charging speeds of 19V/3.5A and the other DC Output port has a charging speed of 12V/10A. The 19V/3.5A is mainly meant for charging laptops and the other DC port is for charging devices such as Digital Cameras.

Car Jumping

The power bank has the ability to jump-start cars about 30 times from its full power capacity and it’s able to jumpstart 7.0L Gas and Diesel Engine cars.

Input Charging:

It is recharged through a DC Input port that has a recharging speed for 14V/1.0A.

Size and Weight:

The size and weight of this power supply are manageable. It’s going to be able to go anywhere with you, however, it’s not something that you’re really going to want to hold and charge your smartphone with. It is, however, a good size that you hold for taking from one destination to another.

It has a length of 9 inches, a width of 3 inches and a thickness of 1.25 inches. The weight of it is 18 ounces, which is about a pound.

Functional Components:

There are two main sides of the power supply that have its functional Components. There’s the short side that has:

  • Car Jumper Port
  • 2 USB ports
  • 110 Lumen LED Flashlight

Then on the long side of the power supply, it has:

  • Power Button
  • The DC Input Port
  • 2 of the DC Output Ports

The power button must be pressed to begin charging and also for jump-starting a vehicle. The flashlight is turned on by double tapping the power button.

Structure and Material:

The structure of the power supply is quite solid even though it’s made of plastic. On the inside when we’re talking about the power is still needs some work.


One of the most common occurrences for car jumper power banks is that when they jump-start a car the batteries have a chance of expanding because of the amount of pressure they’re under. The starting current of this power supply is 300A and the Peak current is 600A.

There are quite a lot of users that have had this power supply expand its batteries when jump starting a car. That result is the casing expanding and the power bank is unusable then. Strangely though, this power supply uses Lithium Ion batteries and they’re less susceptible to expand. Either there are lots of fake power supplies of this type circulating the market or the seller really needs to make changes to the product.


On the reliability side, the power supply is really good because it has 2 USB ports for charging devices such as smartphones and tablets, it also as DC Ports to charge devices such as laptops and other types of them that accept that form of charging. Lastly, it’s able to jump-start cars.

With all that said, there’s the main flaw and that would be the chance of the batteries within the power supply expanding when you jump start a car. If that happens, then the power supply basically breaks and it’s unusable. So when it works like it’s supposed to, then the power supply is great to use.

The power capacity is enough to charge smartphones, tablets, and laptops to their full power multiple times over. It also has two USB ports and two DC Output ports. The thing to top it all off is that it can jump start your car.


It’s quite large and heavy, so, for the most part, you’re going to want to just place this portable charger into your car. All of its parts are easy to find and use.


The build of this Anti-Gravity power supply is questionable because it has a common issue of expanding its batteries when you jump start your car and that results in it breaking. It don’t help that the warranty of the power supply is very strict.


When it works like it’s supposed to with all of its features, then this power supply is very reliable. However, with the common issue of it breaking when you jump start your car, then that results in the power supply being unreliable.
