Makes the tool battery useful far beyond the toolbox
Do you already have 18-20V tool batteries at home? With this compact 220W battery inverter, you can use a compatible battery that portable power supply when you don't have a regular wall outlet.
Connect the battery and access 230 V AC, USB-C, USB-A and 12 V DC – plus a built-in LED light.
Practical at power outages, camping, holiday homes, cars, boats or working in places where there are no electrical outlets.
Available for Makita 18 V, DeWalt 20 V MAX, Milwaukee M18 and Bosch 18 V.
Power where you need it
Instead of buying another separate battery system, you can get more use out of the tool batteries you already have.
With the right battery, the inverter can be used, for example, to:
- charge mobile, tablet and laptop
- keep a router running during a power outage
- power LED lighting
- charge camera and power bank
- power less compatible electrical devices
- use compatible 12 V equipment
When a battery starts to run out, you can easily switch to the next charged battery.
From tool battery to backup power
When the power goes out, it's often the little things that quickly become important: the ability to charge your phone, get light, or keep your internet connection going.
If you already have charged tool batteries at home, the inverter gives them a completely new use. This makes it a compact complement for home supplies, without it having to sit unused for the rest of the year.
The same device can accompany you to the campsite, vacation home, car or workplace.
Four types of outputs
230V AC – up to 220W
For compatible smaller electrical appliances within the inverter's power limit.
USB-C PD 3.0 – 18W
For charging compatible phones, tablets and other USB-C devices.
USB-A QC 3.0 – 18W
For fast charging of compatible USB devices.
12V DC – 5A
For compatible 12 V equipment.
In addition, there is a built-in LED light of 200 lumens, Practical for example during power outages, camping and working in the dark.
How long does the battery last?
The operating time depends on the battery capacity, the load and energy losses in the inverter and connected equipment.
For example, an 18 V/5 Ah battery has a theoretical energy capacity of approximately 90 Wh.
Theoretically, this roughly corresponds to:
| Loading | Theoretical maximum operating time* |
|---|---|
| 10W | about 9 hours |
| 20W | about 4.5 hours |
| 50W | about 1.8 hours |
| 100W | about 54 minutes |
| 200W | about 27 minutes |
*The calculation shows the theoretical energy content of the battery divided by the load. Actual operating time will be shorter and will vary depending on factors such as inverter losses, battery condition, temperature and connected equipment.
If you have multiple compatible batteries, you can change the battery and continue when the first one is discharged.
Fits your battery system
The inverter is available in separate versions for:
Makita 18V
DeWalt 20V MAX
Milwaukee M18
Bosch 18V
Select the version that corresponds to your battery system.

Bought it for traveling and camping. Very handy when there is no power outlet nearby
I've been using it for a few weeks now and everything works as it should.

Handy little inverter, works well with my Makita battery
Let customers speak for us
from 2376 reviewsI bought it because it's underwired and I don't regret it. It provides good support without chafing, and it's a very good price.
It took a while for it to arrive but since then it has worked perfectly for the size and price. As a customer I am completely satisfied! Thank you!

Good sound, fits very well, I have a smaller ear canal in one ear, so these are soooo perfect, and a nice design, bought the beige ones, Thank you!!
