In Short

The FirstPower Pro 300W Power Supply Inverter is a portable powerhouse that converts DC power from your 20V Dewalt or 18V Milwaukee battery into AC power, just like a regular wall outlet. This means you can charge your devices, run your tools, or power your electronics anywhere, anytime.

What a battery-powered 300W inverter can run

This inverter runs from a 20V DeWalt or an 18V Milwaukee tool battery and gives AC outlets, USB ports and a Type-C port, which makes it a good fit for phones, a laptop or a small fan. The limit is the battery: divide the pack’s watt-hours by the load’s watts to estimate the runtime. A 5Ah, 20V pack holds about 100 watt-hours, so a 60W laptop charger would run for around an hour and a half, less after conversion losses. A 300W load would drain the same pack in about 20 minutes.

Who it suits, and who should skip it

It suits owners of DeWalt or Milwaukee batteries who want emergency power, camping power or a job-site outlet without a separate battery system. Skip it if you want to run loads above 300W or for many hours, since a tool battery cannot supply that.
