Easy Plug-and-Play Addition to the F3000
A solid addition to the F3000 setup. Installation is straightforward and quick. The charging plan on the F3000 is preferred over the C1000 because it distributes the charge evenly between the inverter base battery unit and the add-on battery.
Pros
- + Easy setup
- + Even charge distribution between base and add-on battery
- + Preferred charging plan over C1000

Included Cable Works for Separate Expansion Battery
The cable included with a separately purchased expansion battery is not too short and can reach when the battery is placed on top of the main unit. The ends are not interchangeable, which can make connection confusing. The user manual shows two different cable lengths, including a longer cable between the main unit and the first expansion battery. After some effort, the connection was made and the battery is charging.
Pros
- + cable reaches when battery is placed on top
- + battery is charging
Cons
- − cable ends are not interchangeable
- − manual shows two different cable sizes, causing confusion

Expansion battery doubles capacity for F3000
This expansion battery doubles the capacity of an Anker F3000 power station. The included power cable is long enough to connect when the battery sits directly on top of the station, and when using multiple expansion batteries, one battery can plug into another with the same cable. The F3000 supports up to three expansion batteries. With a roughly 150 W draw, adding one expansion battery uses about three hours of AC grid power per day. Two 200 W solar panels also add PV power. Depending on needs, another F3000 may be preferable, but this met the intended use well.
Pros
- + doubles capacity of F3000
- + included cable long enough for stacked placement
- + supports daisy-chaining multiple expansion batteries
- + reduces daily grid power use for a 150 W draw
Cons
- − another F3000 may be preferable depending on needs
