Full Product Description

Reliable Off-Grid Power for Every Adventure

Never let a dead battery cut your trip short. The 300W Portable Power Station is a compact, heavy-duty energy hub designed for remote workers, outdoor photographers, and camping enthusiasts. Weighing only 2.9kg (6.4 lbs), its rugged, ergonomic handle makes it incredibly easy to carry. Whether you are powering a mini-fridge at a campsite or keeping your Wi-Fi router alive during a power outage, this massive 230Wh (55000mAh) power station delivers consistent, reliable energy wherever you go.

Ultra-Safe LiFePO4 Battery Technology

Not all portable power stations are created equal. This unit is powered by advanced LiFePO4 (Lithium Iron Phosphate) battery chemistry. Unlike traditional lithium-ion batteries that degrade quickly, LiFePO4 cells offer exceptional thermal stability and a lifespan that lasts up to 6 times longer (over 2000 cycles). Combined with a built-in Battery Management System (BMS) that protects against overcharging, short circuits, and extreme temperatures, this is an investment that will safely power your gear for years to come.

Pure Sine Wave AC & 7 Simultaneous Ports

Protect your expensive electronics. The built-in universal AC wall outlet delivers 300W of Pure Sine Wave power, ensuring delicate devices like laptops, CPAP machines, and camera battery chargers run smoothly without electrical interference or damage. With 7 output ports—including three QC3.0 USB-A ports, a PD 45W USB-C port, and three 12V DC outlets—you can charge up to 7 devices simultaneously with a combined total output of up to 500W.

💡 Pro Tip from Our Technicians

"A common mistake buyers make is overloading their power station. Remember, the AC outlet supports a maximum of 300W. Devices with heating elements (like small travel kettles or hair dryers) often exceed this and will trigger the automatic safety shutdown. To estimate your run time for AC appliances, use this formula: 230Wh × 0.85 ÷ Your Device's Wattage. For example, a 50W laptop will run for about 4 hours. If you are planning an off-grid solar setup and aren't sure which DC5521 solar panel to pair with this unit, drop by our Sham Shui Po store! Our team at Sun Cheong Computer Co. Ltd. will help you calculate your exact power needs on the spot."

FAQ Section

Why does it say both 230Wh and 55,000mAh? Which one is correct?Both are correct! "230Wh" (Watt-hours) is the true measurement of the total energy stored, which is used to calculate how long AC appliances (like laptops or fans) will run. "55,000mAh" is the equivalent capacity if you compare it to a standard 3.7V/4.2V smartphone power bank. To put it simply: this power station holds the same amount of energy as 5.5 standard 10,000mAh power banks, giving you massive off-grid power!
Can I use this 300W power station while it is charging via a solar panel?Yes! This power station supports pass-through charging. You can plug a solar panel into the DC5521 input port to recharge the battery while simultaneously drawing power from the AC, USB, or DC ports to charge your devices.
What is the difference between LiFePO4 and standard lithium-ion power stations?LiFePO4 (Lithium Iron Phosphate) is a much safer and more durable battery chemistry. While standard lithium-ion batteries typically degrade after 500 charge cycles, LiFePO4 batteries can last for over 2,000 to 3,000 cycles (lasting up to 6 times longer). They are also highly resistant to thermal runaway, making them the safest choice for outdoor and vehicle use.

Target Users / Applications
