EnginStar Portable Power Station 300W is a compact, 296Wh rechargeable generator that delivers quiet, pure-sine AC power and multiple outputs for charging phones, laptops, CPAPs, and small appliances on the go.

This lightweight unit measures roughly 9 x 5.5 x 7.5 inches and weighs about 6.5 pounds, combining convenient size with enough stored energy to keep essential devices running during outdoor trips, short power outages, or when working remotely. With ETL certification, integrated safety controls, and three ways to refill its battery, the EnginStar 296Wh power station balances portability, performance, and protection for everyday and emergency uses.

How much gear can this power station actually run?

The EnginStar unit supplies 296 watt-hours of stored energy and continuous 300W AC output via pure sine wave inverters, suitable for sensitive electronics and small household devices. It has eight output ports to charge multiple items simultaneously without relying on a noisy gas generator.

• 296Wh battery capacity for phones, tablets, cameras, laptops, and small appliances
• 300W continuous AC output with two 110V pure sine wave outlets
• 2 regulated DC ports (12V/24V), USB fast charge (5V/3.1A), and 18W USB-C
• Support for devices like CPAPs, mini-fridges, drones, and charging stations

How quickly and in what ways can I recharge it?

There are three practical ways to restore the battery: solar panel input, standard wall outlet, or a 12V car socket. With up to 65W input, the unit can reach roughly 80% charge in about two hours under optimal AC charging conditions.

• Solar recharge via compatible 12–25V panels (solar panel sold separately)
• Fast AC charging from a household outlet with included home charger
• 12V car charger for on-the-road top-ups
• Built-in controller to optimize solar charging speed and efficiency

What safety and longevity features protect the battery?

The EnginStar power station uses an advanced battery management system to guard against common electrical faults and to stabilize voltage and temperature during use and charging. High-quality lithium-ion cells are specified to support many charge cycles, helping the product last through repeated adventures and emergencies.

• Battery management with overcharge, short-circuit, overload, and temperature safeguards
• ETL certification for electrical safety compliance
• Original lithium-ion cells rated for more than 1,000 charge cycles
• Recommendations to recharge every 2–3 months to preserve battery health

Which accessories come in the box and what should I expect?

The package includes everything needed to start using the power station right away, plus guidance for safe operation. Solar panels are not included, so plan to purchase a compatible panel if you want off-grid recharging.

• 1 x EnginStar Rechargeable Power Station (296Wh, 300W)
• 1 x Home AC charger and 1 x car charger cable
• 1 x User manual and 12-month limited service coverage
