  • Long-Lasting Portable Power Station With a 10-Year Lifespan: With our proprietary long-lasting technology InfiniPower™, combined with LiFePO4 batteries, ultra-durable electronic components, a smart temperature control system that monitors temperature up to 100 times per second, and impact-resistant structural design, Anker 521 PowerHouse is built to last over a decade, even with everyday use.
  • Huge 256Wh Capacity: The high capacity portable power station pumps out 256Wh of power—the perfect companion to charge your devices and small appliances during a weekend trip.
  • Smart Sunlight Alignment: Equipped with Anker's proprietary Suncast technology, adjust the solar panels properly to capture direct sunlight for maximum charge. Get a full charge in 4.1 hours under direct sunlight.

Clean and Efficient Solar Energy

Harness the clean, renewable energy of the sun with a high conversion efficiency that converts up to 23% of solar energy into electrical energy.

Smart Sunlight Tracking System

With Suncast technology's guidance, adjust the panels properly for optimal solar charging.

A Place for All Your Devices

The high-capacity power station pumps out power to all your mobile devices, computers, small appliances, and emergency equipment with zero interference. 

Power-Saving Mode

To reduce energy waste, the power station will instantly power off once your devices are fully charged. For a stable and optimal charge, simply turn off power-saving mode. 

Smart LED Display

Easy-to-read LED display shows the remaining battery capacity, current input and output status, as well as estimated recharge time.


  • When the control buttons are turned on, even if no devices are being charged, there will still be a certain amount of no load power consumption. We recommend turning off the control buttons after using them to avoid draining power.
  • Incompatible with appliances that require more than 200W input such as microwave, electric grill, refrigerator, electric vehicle, air compressor, and more.
  • Do not use with CPAP machines overnight and when in Power Saving mode.
  • The power station supports pass-through charging while connected via a vehicle output or AC outlet.
  • Please remove the protective film on the screen before using it for the first time.
  • The first time you use the device, the battery may appear to drain faster than normal. Discharge the battery to 1%, then recharge to 100%, and PowerHouse will automatically calibrate for future use.
  • Use any 12V-28V solar charger with a DC 7909 male connector to charge the power station.
