ZELMT 300W Car Power Inverter DC 12V to 110V AC — 2 Outlets + 30W PD USB, 700W Surge, Compact

The ZELMT 300W Car Power Inverter converts a vehicle’s 12V DC into two 110V AC outlets plus two USB ports (including 30W PD) so you can run laptops, phones, and small appliances on the road.

If you need reliable power away from a wall socket, this compact inverter gives you desktop-style outlets and fast USB charging from your car’s cigarette lighter or accessory port. It delivers 300 watts continuous output with a 700W surge capability for short bursts, and an internal blower plus safety circuitry to protect connected devices. The chassis is lightweight yet reinforced with aluminum and flame-retardant ABS so it can endure travel wear while staying electrically insulated.

How much power will this inverter actually supply?

This unit provides 300W of continuous AC power and can handle up to 700W peak for brief startup surges from devices like vacuums or small power tools. The two AC outlets share the total wattage; sum of all devices should not exceed the continuous rating to avoid overload.

• 300 watts continuous; 700 watts peak for short durations
• Two 110V AC outlets for laptops, chargers, and small appliances
• Two USB ports including 30W USB-A Power Delivery for faster device charging
• Best for items under the continuous wattage limit (check device labels)

Will my devices stay safe while charging in the car?

Yes — the inverter includes a multi-protection suite and thermal management to minimize risk to electronics. A built-in 40A fuse protects against undervoltage and overcurrent, while overheat and short-circuit protection shut the unit down if conditions become unsafe.

• Active cooling fan prevents overheating during sustained use
• 40A fuse guards against overcurrent and voltage irregularities
• Short-circuit and over-temperature automatic shutdown
• Flame-retardant ABS casing and aluminum housing improve insulation and durability

How portable and convenient is the ZELMT 300W inverter?

Designed to be roughly the size of a smartphone, this inverter slips into glove compartments, backpacks, or center consoles for easy transport. It plugs into a standard car 12V outlet so installation is tool-free and immediate, making it useful for road trips, work commutes, and outdoor activities.

• Compact, pocket-sized form factor for easy storage
• Plugs into any vehicle 12V accessory socket—no wiring required
• Lightweight aluminum shell resists impacts and travel wear
• Included user manual and responsive ZELMT support for setup help
