Pros & Cons
Anker SOLIX C300
Pros
- +Nine outputs including three AC and a 140W two-way USB-C — the most connected small station here
- +63 minutes to full is fast for the class
- +10ms UPS is quick enough for a desktop PC
- +Both Bluetooth and Wi-Fi app control
Cons
- −288Wh and 300W keep it in the phones-laptops-CPAP bracket, not appliances
- −100W solar input
- −Not expandable
- −A newer C300X adds a second 140W port and is replacing this model
Anker SOLIX C1000 Gen 2
Pros
- +2,000W continuous with a genuine 3,000W surge is the strongest real output at 1kWh here
- +49 minutes to full is the fastest recharge of any station in this list
- +Five AC outlets and two 140W USB-C ports
- +Routinely discounted to around half its list price
Cons
- −Gen 2 deliberately removed battery expansion — if you want the add-on pack you need the Gen 1 C1000 or C1000X instead, which is easy to get wrong when both are listed
- −Only 12W from the single USB-A port
- −600W solar is good but well behind the EcoFlow's 1,000W
