Anker Solix C300 DC

Manufacturer: Anker

The Anker Solix C300 DC is a compact portable power station designed for users who need reliable off-grid power in a lightweight, carry-anywhere form factor. Weighing 2,800 g and built with a carry handle, it strikes a balance between portability and utility. It includes an LED light, a display, and smartphone remote control via Wi-Fi and Bluetooth, giving users convenient oversight of the unit without needing to be right next to it. A three-year warranty rounds out the ownership experience.

On the technical side, the Anker Solix C300 DC supports up to 100 W of solar input and houses a 288 Wh battery, making it suited for recharging smaller devices over extended periods. Its seven outputs break down into four USB-C ports, two USB-A ports, and one car port, with no AC or TT-30 outlets present. The unit measures 200 mm in height, 119 mm in width, and 121 mm in thickness, giving it a volume of roughly 2,879.8 cm³. It does not include a wireless charging pad or UPS mode.

Pros
  • Equipped with Wi-Fi and Bluetooth, allowing the unit to be monitored and controlled remotely via smartphone
  • Four USB-C ports provide ample connectivity for modern devices without requiring adapters
  • At 2,800 g with a built-in carry handle, it is light enough to transport by hand without much effort
  • A three-year warranty offers solid coverage for a portable power station in this class
  • The onboard display gives real-time visibility into the unit's status without needing a connected device
  • An integrated LED light adds hands-free utility during power outages or outdoor use
Cons
  • No AC output ports limits compatibility with standard household appliances and larger electronics
  • Absence of UPS mode means it cannot serve as an uninterruptible power supply for sensitive equipment
  • Maximum solar input of 100 W may result in slow recharge times under real-world conditions
  • No wireless charging pad, so devices must be physically connected via cable to charge
  • The display does not support touch input, which may feel less intuitive compared to touch-enabled alternatives
Who is this for?

This unit is a practical fit for users who need a lightweight, portable DC power source for day trips, camping, or outdoor activities where carrying weight matters. The combination of four USB-C ports, two USB-A ports, and a car port makes it well suited for keeping phones, tablets, and small 12 V accessories charged away from the grid. Users who value remote monitoring via smartphone — whether managing solar input or checking battery levels — will appreciate the built-in Wi-Fi and Bluetooth connectivity, particularly in off-grid or van-life scenarios where the unit may not always be within arm's reach.

Who is this NOT for?

This product is not a good match for users who need to power standard household appliances or AC-dependent devices, since it carries no AC output ports whatsoever. It is equally unsuitable as a backup power solution for sensitive electronics that require uninterruptible power supply functionality, given the absence of UPS mode. Users with high energy demands or those looking to run multiple power-hungry devices for extended periods will likely find the 288 Wh battery capacity and 100 W solar input ceiling limiting for sustained, heavy-duty use.
