Eg009Li 300w Portable Battery
The 300W Portable Battery is a high-capacity, ultra-compact energy hub designed to keep your essential devices running anywhere. Unlike traditional generators, this unit contains no fuel, produces no fumes, and operates in near silence. It pairs a high-density lithium-ion battery with a pure sine wave inverter, delivering clean, stable 300W of continuous power (with surge capacity for heavier starts). Equipped with a variety of output ports and multiple recharging methods (wall outlet, car socket, or solar panel), it serves as a reliable bridge between your daily life and the great outdoors—or between you and an unexpected blackout.

The 300W Portable Battery is a high-capacity, ultra-compact energy hub designed to keep your essential devices running anywhere. Unlike traditional generators, this unit contains no fuel, produces no fumes, and operates in near silence. It pairs a high-density lithium-ion battery with a pure sine wave inverter, delivering clean, stable 300W of continuous power (with surge capacity for heavier starts). Equipped with a variety of output ports and multiple recharging methods (wall outlet, car socket, or solar panel), it serves as a reliable bridge between your daily life and the great outdoors—or between you and an unexpected blackout.
With double the capacity of a 150W unit, this 300W model expands your possibilities significantly:
Camping & RV Living: Power a 30–50L portable fridge/freezer for 10–20 hours. Run CPAP machines (without heated humidifier) for a full night, charge multiple phones, laptops, drones, and camp lights simultaneously.
Emergency Home Backup: Keep a Wi-Fi router, cable modem, security camera hub, LED lamps, small fan, and a 32" TV running for hours during a power outage. Ideal for powering a heated blanket or electric lunchbox for warm meals.
Outdoor Work & Photography: Run a 15" laptop for 6–8 hours, charge camera batteries repeatedly, power a portable projector for an outdoor movie night, or run a small 12V water pump for gardening or events.
DIY & Jobsite Tools: Power compact drills, rotary tools (e.g., Dremel), soldering stations, glue guns, and small work lights. Great for remote repairs or installations without a wall outlet.
Medical & Mobility: Reliable backup for portable oxygen concentrators (certain low-flow models), recharges electric wheelchairs/scooters, and powers small CPAP machines during travel.
Double the Power, Same Portability: At roughly 6 lbs (3 kg), it's still easy to carry in one hand. Provides 2x the watt-hours (typically 250–350Wh) of a 150W unit, giving you extended runtime for more demanding devices.
Clean & Safe Energy: Pure sine wave inverter protects sensitive electronics (laptops, CPAP, medical devices). Zero carbon monoxide risk, no fuel smell or spillage safe for indoor use, bedroom, tent, or RV.
Versatile Multi-Device Charging: Features an AC output (300W continuous, 600W+ surge), multiple USB ports (including USB-C with Power Delivery up to 60W for fast-charging laptops), and a 12V DC car port. Run several devices at once with confidence.
Fast Solar & Multi-Way Recharging: Supports solar panel input (up to 100W–120W), reaching full charge in 3–6 hours under good sun. Also recharges via standard wall outlet (3–4 hours) or 12V car port (4–6 hours). Pass-through charging allows you to use the unit while it's being recharged.
Intelligent Battery Management System (BMS): Built-in BMS protects against over-voltage, over-current, overheating, short circuits, and excessive discharge. The lithium battery typically offers 800–1,000+ charge cycles while maintaining 80% capacity.
Emergency Ready: Many models include an integrated LED flashlight with SOS mode. The large, easy-read display shows remaining battery percentage, input/output wattage, and estimated runtime at a glance.
