Wolfbox MegaVolt 24Air - Jump Starter with Air Compressor

[Julian23]

Since I started covering some interesting products made by dashcam companies that aren't a dashcam, here is another handy device.
This time it's a 2-in-1 product, a jump starter with an air compressor. (Wolfbox claims it's a 4 in one device if we count the fast charging and emergency lighting.)

Specs

• Peak current: 4000 A
• Internal battery: 24,000mAh/88.8Wh
• 15V / 10A DC output for small devices
• 45L/Min Tire Inflator, max 160PSI
• USB-C and USB-A outputs for charging phones and tablets. (65W Fast-Charging)
• Large and sharp LCD display
• 400 lumen flashlight with different modes: Constant, strobe, SOS

Here are some pictures.
The MegaVolt 24Air will arrive in a cardboard box in the usual Wolfbox design.

Inside, the MegaVolt 24Air and its accessories are neatly packaged into the included storage bag.
The storage bag is a card case that will keep its shape. It will allow users to place it anywhere in the car and not worry about it.

Wolfbox includes the obviously required clamp, air hose, USB-C cable, and 3 different air nozzles.
The clamps have a decent weight to them and don't feel cheap. They will hold on tightly without losing grip.

On the connector of the clamps is a button to "force" a boost if a battery is not detected while connecting the clamps.
If the battery is detected, the correct light will glow green.

There are 3 different air nozzles included. Somehow, I got one more of the middle piece. Won't complain about it.

Here are some more pictures of the unit:

The MegaVolt 24Air has a nice, big and easy to read display.

At the top of the unit is the output for the air compressor, USB in and output, and a 15V, 10A bullet-style connector output.

A quick look at the USB-A and USB-C ports at the top of the unit.

On the top left is the covered port for the jumper cable clamps.
The connector firmly connects to it.

At the top of the unit we will find a flashlight with a claimed output of 400 lumens. The flashlight also has modes like SOS, strobe to get the attention of others.

The back has all the specs and a manual on how to use the product. Nice detail.

Once the clamps are plugged into the jump unit, the display will automatically turn on.

If the unit senses a battery, the car can be started without having to press any button on the unit.

Wolfbox MegaVolt 24Air provides so much power on the startup that it feels like the car has a brand new, freshly charged battery.
Absolutely nice to see it provide so much power.

The USB-A output is unfortunately limited by an 8-hour timer. After that time, it will disable the output and turn off the device.
This means it can't be used as a dashcam battery.
8 hours are more than enough to charge any device like a phone, tablet, notebook, drone, etc.

Now let's talk about the air compressor.
Having used smaller battery-powered air compressors in the past, I can definitely say that this one is much stronger. It has a claimed max pressure of 160 PSI. I used up to 3.3 bar and it didn't struggle.
Several units can be selected: PSI, BAR, KPA, Kg/cm²
It might not be the quietest, but the combination of the jump starter and air compressor is a very nice package.

Build and Handling
The MegaVolt 24Air has the usual Wolfbox quality and feels well-built. The display is big, sharp and easy to read. The charge level of the battery will be shown with 4 bars. The 400-lumen flashlight can help to light up tires, the engine bay or other things in the night.
The only downside is the 15 V DC output. While it’s nice to have, I’d personally prefer something between 12 and 13.5 V to better match typical automotive accessories.


Good Stuff

• Starts weak or even completely dead batteries with no issues
• Everything that is needed is included
• Fast charging from the USB-A or USB-C output
• Big, clear display
• Bright flashlight with multiple modes
• DC output for accessories
• Strong air compressor to fill up tires or other things

Criticism

• 15V output instead of 12-13.5V
• Charge level only with 4 bars
• No handle on the bag, just a loop to hold it
• 8h timer for the USB ports

Summary
The MegaVolt 24Air is a nice "just in case" unit that can save the day if something goes wrong.
It has been in my car for the past weeks and will continue to stay there. It has never been easier to jump a bad or flat battery and to inflate a tire.
If it's in your budget, get one.

Nice review. I looked at this for a while and the price was good, but ended up buying the smaller battery-only model from Wolfbox without the air compressor.

Thanks Tony!
If the compressor isn't needed, then the smaller version will be even more convenient.
The 2 in 1 version is awesome to have if something goes wrong.
