About the Anker SOLIX C300X
From our tech experts at CEN
The Anker SOLIX C300X is a 288Wh LiFePO4 power station with 300W continuous output, or up to 600W through SurgePad, across seven outlets. On the UK version that means two AC sockets, a 120W car socket, two 140W USB-C, a 15W USB-C and a 12W USB-A. It recharges from the wall to 100% in 70 minutes and has a 5-year warranty.
Who it suits
Campers and home users who want a small station that also runs low-power mains kit such as a projector or mini fridge. UPS mode switches over in under 10ms, which suits a router or PC. At 4.1kg it is heavier than the 2.8kg C300X DC, and for more capacity step up to the C1000 Gen 2.
Our tech experts advise
Check the wattage of anything you plan to run: SurgePad handles appliances up to 600W, so a kettle or heater is beyond it. Solar input is up to 100W via XT60, making the PS100 bifacial panel a natural partner. See all portable power.

Frequently Asked Questions
Q: What can this power station actually run?
A: Compare the output wattage in the Specification tab with the wattage of what you want to run. As a guide, phones and lights draw very little, a cool box or TV a moderate amount, and heaters or kettles need the largest units.
Q: Can I charge this power station with solar?
A: Most portable power stations accept solar input, and compatible solar panels are listed in the Specification tab and stocked by CEN. Solar makes them a genuinely off-grid solution for camping and van life.
Q: Can I take a portable power station camping or in a campervan?
A: Yes, that is exactly what they are designed for: silent, fume-free power for lighting, devices, fridges and equipment wherever you are, with no fuel or servicing.
Q: How long does the Anker SOLIX C300X take to recharge?
A: From a wall outlet it reaches 80% in 50 minutes and 100% in 70 minutes. With a portable solar panel (up to 100W) it reaches 80% in 2.7 hours. It can also be recharged from your car or through the PD 3.1 USB-C port.
Q: Which solar panel works with the C300X?
A: Anker recommends pairing it with the Anker SOLIX 100W Portable Power Panel. The C300X is not compatible with the Anker SOLIX PS30 Portable Solar Panel.
Q: How long will the C300X run my devices?
A: As a guide from its 288Wh battery: an iPhone (12Wh) about 20.3 charges, a laptop (49Wh) 5 charges, 5W lights 38 hours, a 40W mini fridge 6.5 hours and a 60W projector 4.5 hours.
