Makita Powered Inverter Generator 150W - Portable Makita Battery

In this review the Makita Powered Inverter Generator 150W from BTRUI is presented as a compact, portable DC to AC inverter designed for Makita 18V batteries. The bottom line: this small inverter is for users who need occasional power for electronics on the jobsite, camping, or during short power interruptions; the single biggest reason to buy is its convenience and compatibility with common Makita 18V packs, offering AC outlet and USB ports in a phone-size package. It is not intended to run high-draw appliances, but it excels at keeping laptops, phones, lights, and small devices powered.

Key Features

• 150W AC Output: Provides a standard 110V~120V household socket suitable for devices below 150W such as chargers and small electronics.
• Dual USB Ports: Two USB outputs deliver DC 5V/2.4A combined that make charging phones and tablets straightforward without needing extra adapters.
• Compact Portability: Phone-size design and compatibility with Makita 18V batteries make it easy to carry on jobsites, camping trips, or in a vehicle for emergency backup.
• Built-in LED Light: The 200lm LED provides useful illumination for campsite tasks or work in low light and adds practical utility beyond power conversion.
• Safety Protections: A small fan and internal fuse aid heat dissipation and short circuit protection to reduce the risk of overheating during use.

Who It's For

The inverter is aimed at tradespeople, campers, and anyone who owns Makita 18V batteries and needs portable AC and USB power for electronics like laptops, phones, cameras, or small lights. Its compact size and Makita battery compatibility make it a good accessory for jobsite tool packs and travel gear.

Those who require sustained power or need to run devices above 150W should look elsewhere; this unit will not support most power tools, fridges, coffee makers, or microwaves. Also, it is not a battery charger and cannot charge the battery while converting power.

• Built-in fan and fuse provide extra safety during operation.

Cons

• Battery life is limited for high-draw devices and several customers reported it can drain relatively quickly under load.

Specifications

Our Verdict

This Makita-compatible 150W inverter is a practical, low-cost way to add AC and USB power to existing 18V battery packs for on-the-go charging and light duty needs. It represents good value for users who need occasional power for electronics and appreciate a compact, safety-minded design, but those needing long runtimes or to run high-wattage appliances should choose a higher-capacity solution.
