What to look for in a power inverter for tool battery charging
There are two different ways an inverter can be involved in charging cordless tools. The first is direct battery charging through a purpose-built charging port. The EGO model is the clearest example here, since its manufacturer-listed USB-C PD port supports charging EGO 56V ARC Lithium batteries. The second is indirect charging: the inverter produces AC power, and you plug a compatible tool battery charger into its AC outlet.
For indirect charging, the inverter’s continuous wattage matters more than its peak figure. A charger may draw a modest amount of power, but the inverter still needs enough continuous capacity for the charger and any other connected devices. Peak output is intended for short startup demands, not for sustained charging. None of the listings here provide the input wattage of a specific DeWALT, Milwaukee, Ryobi, or other charger, so verify that figure before buying.
Battery-platform compatibility is also critical. A DeWALT-compatible inverter is not a universal 18V or 20V tool battery adapter, and the same applies to Milwaukee and Ryobi models. The battery is not included with the battery-mounted inverters in this selection. The Pro Chaser model instead connects to a vehicle’s 12V supply, while the EGO model requires an EGO 56V ARC Lithium battery for its battery-powered operation.
Prices listed here range from $20.99 to $148.00 and can change. Confirm the current price, included accessories, and manufacturer compatibility information before ordering. CarTechTalk may earn a commission from qualifying purchases.
Best power inverter choices by charging scenario
Best for direct EGO battery charging: EGO POWER+ Portable Inverter, 400W
The EGO POWER+ Portable Inverter, 400W is the most direct fit for an EGO owner. The manufacturer lists compatibility with all EGO 56V ARC Lithium batteries and identifies its 100W USB-C PD port as an input and output connection that can charge those batteries. It also provides 400W of continuous power, 800W of peak power, a 120V outlet, two additional USB connections, and pass-through charging while an EGO battery charges through the USB-C PD port.
Drawback: the battery and charger are not included, and the direct battery-charging feature is specific to the EGO 56V ARC Lithium system. Avoid if: you use DeWALT, Milwaukee, Ryobi, or another tool platform and do not already own EGO batteries.
Best for a vehicle powered charging setup: Pro Chaser 400W Power Inverters for Vehicles DC
The Pro Chaser 400W Power Inverters for Vehicles DC is the practical choice when your charging source is a vehicle rather than a slide-on tool battery. The manufacturer lists 400W of continuous AC power, 800W of peak output, two AC sockets, and dual USB ports. That gives you a way to run a separate tool battery charger from a vehicle’s 12V electrical system, provided the charger and vehicle power outlet stay within the inverter’s limits.
Drawback: it requires a vehicle 12V DC source and does not provide a tool-battery interface. Avoid if: you need portable charging away from the vehicle or want an inverter that attaches directly to a cordless-tool battery.
Best high-output DeWALT platform option: Ecarke 350W Power Inverter Compatible with DeWALT
The Ecarke 350W Power Inverter Compatible with DeWALT accepts a compatible DeWALT 20V battery and lists 350W of AC output. Its separate AC and DC controls, display, low-voltage shutdown, and multiple protection features make it more informative than a basic battery adapter. The AC outlet can run a separate DeWALT charger, while the USB-C, USB-A, 12V DC, and LED functions support other job-site needs.
Drawback: the listing says the battery and charger are sold separately, and it requires removing the battery after use for storage. Avoid if: you want a simple plug-in vehicle inverter or do not own a compatible DeWALT battery.
Best compact DeWALT value: Ecarke 220W Portable Power Inverter Compatible
The Ecarke 220W Portable Power Inverter Compatible is a smaller DeWALT option for users who only need enough AC capacity for a compact charger and light electronics. The manufacturer lists compatibility with DeWALT 20V batteries, one AC outlet, two USB-A ports, a 20W Type-C port, and a work light. Its low-voltage protection is listed as shutting down below 15V.
Drawback: its listed continuous AC output is lower than the 350W Ecarke model, limiting the amount of equipment that can share the inverter. Avoid if: your charger or accessory load could approach 220W, or if you need multiple AC outlets.
Best Milwaukee platform value: Ecarke 220W Portable Power Inverter Compatible
The Milwaukee version of the Ecarke 220W Portable Power Inverter Compatible is aimed at users who already have Milwaukee 18V batteries. It lists 220W of continuous AC output, a 250W peak figure, one AC outlet, two USB-A ports, a 20W Type-C connection, cooling, and low-voltage protection. That combination is suitable for running a compatible Milwaukee charger along with small personal electronics, subject to the charger’s input requirements.
Drawback: it has only one AC outlet and does not include a Milwaukee battery or charger. Avoid if: you need to charge several AC-powered tool chargers at once or want direct charging of a Milwaukee battery through a dedicated charging port.
Best Ryobi platform value: Ecarke 220W Portable Power Inverter Compatible
The Ryobi version of the Ecarke 220W Portable Power Inverter Compatible offers the same general 220W class of AC output, but its key advantage is compatibility with Ryobi 18V batteries. The manufacturer lists one AC outlet, two USB-A ports, a 20W Type-C port, LED lighting, a cooling fan, and protection against over-current, overload, overheating, and short circuits.
Drawback: the listed Type-C output is 20W, which is more limited than the 65W USB-C PD connection on the KOEZEOI model. Avoid if: you need faster USB-C laptop charging or more than one AC-powered charger connection.
Best Ryobi option for higher USB-C output: 300W Power Inverter Compatible with Ryobi 18V
The 300W Power Inverter Compatible with Ryobi 18V from KOEZEOI is the stronger Ryobi choice for users who want more AC headroom and USB-C charging. The manufacturer lists 300W of AC power through two outlets, a 65W USB-C PD port, and an 18W USB-A port. It also identifies several Ryobi battery models as compatible and lists automatic AC shutdown below 15.5V.
Drawback: simultaneous USB-A and USB-C use can reduce the combined output to a stated maximum of 10W. Avoid if: you expect both USB ports to deliver their maximum advertised output at the same time, or if you do not have one of the listed compatible Ryobi batteries.
Best Milwaukee option with a 30W USB-C port: 220W Azocek Power Inverter Compatible
The 220W Azocek Power Inverter Compatible is another Milwaukee 18V option. Its manufacturer lists one AC outlet, two 18W USB QC ports, and a 30W PD Type-C port, along with a 400LM adjustable light. For a Milwaukee owner, that port selection gives more USB-C capacity than the 20W Ecarke alternative while retaining an AC outlet for a separate tool battery charger.
Drawback: the listing does not identify a direct Milwaukee battery charging function, so the AC outlet remains the relevant path for a conventional Milwaukee charger. Avoid if: you need direct battery charging or more than one AC outlet.
Best Ryobi option with a simple emergency format: LIVOWALNY 220W to 250W Power Inverter Compatible
The LIVOWALNY 220W to 250W Power Inverter Compatible is designed around Ryobi 18V batteries and lists 220W of real AC power with a 250W peak figure. It includes one AC outlet, two USB ports, a 36W Type-C output, and an adjustable 200LM LED light. That makes it a reasonable fit for a Ryobi owner who wants one compact inverter for a charger, phones, and lighting.
Drawback: the product has one AC outlet and does not include the battery. Avoid if: your charging station needs multiple AC outlets or you want a higher-power USB-C PD port for a laptop.
Best DeWALT option with 30W USB-C charging: Azocek 220W Power Inverter Compatible with Dewalt
The Azocek 220W Power Inverter Compatible with Dewalt lists compatibility with DeWALT 18V and 20V batteries, including DCB206, DCB205, and DCB204. Its connection layout includes one AC outlet, two 18W USB QC ports, and a 30W PD Type-C port. The manufacturer also lists a 400LM adjustable light and protection against short circuits, overcurrent, low voltage, overheating, overload, and over-discharge.
Drawback: it provides only one AC outlet and does not list direct DeWALT battery charging through USB-C. Avoid if: you need to run several AC chargers or want the highest AC output in this group.
How to choose between a vehicle inverter and a tool battery inverter
A vehicle inverter is usually the better ownership choice if you already drive to the job site and need to recharge several battery systems. The Pro Chaser model offers two AC outlets, so it can be more flexible than a single-outlet battery adapter. Its limitation is dependence on the vehicle’s 12V supply, along with the vehicle’s own electrical and outlet limits.
A tool battery inverter is more portable and can work away from the vehicle, but it consumes the same batteries needed for cordless tools. That creates an ownership tradeoff: a large tool battery may provide useful runtime, but every charging session also reduces the energy available for the tools themselves. The listings do not provide battery runtime or charger input figures, so those costs cannot be estimated reliably here.
Direct charging is the simplest match when it is explicitly supported, which is why the EGO model stands apart. For the DeWALT, Milwaukee, and Ryobi options, treat the AC outlet as a way to run a separate charger, not as proof that the inverter itself charges the tool battery directly.
Who should skip these inverters
Do not buy anything in this guide if you need to power a high-draw tool, a large shop charger, or a full job-site charging station and have not confirmed the charger’s input demand. These are compact inverter products, and the listed outputs range from 220W to 400W continuous, with the EGO model also offering a direct 100W USB-C battery-charging path for its own platform. A buyer who needs extended runtime, multiple high-power chargers, or guaranteed charging speed should instead look for a larger portable power station or a purpose-built manufacturer charging system with documented input and output specifications.

Final verdict
Choose the EGO POWER+ Portable Inverter, 400W if you own EGO 56V ARC Lithium batteries and want the clearest documented direct charging route. Choose the Pro Chaser 400W Power Inverters for Vehicles DC if your priority is running a separate charger from a vehicle and having two AC outlets. DeWALT users can choose between the higher-output Ecarke 350W model and the smaller 220W options, while Milwaukee and Ryobi owners should select the adapter built for their battery platform. Before ordering, confirm the exact battery model, charger input wattage, inverter continuous output, and whether the charger must be connected through AC or can use a documented direct charging port.
