The EcoFlow GLACIER Plug-In Extra Battery, which EcoFlow calls the GLACIER Plug-in Battery (model EFBX100-EB), is a 298Wh, 4.2 lb (1.9 kg) battery pack that slides into the battery compartment of an EcoFlow GLACIER Classic 35L, 45L or 55L or an original EcoFlow GLACIER. It lets the fridge keep running away from a wall outlet or vehicle socket.
It also works on its own as a 100W USB-C power source. It suits campers, anglers, tailgaters and road trippers who want cold food away from a plug and a way to keep phones and laptops charged.
The pack stores 298Wh at 21.6V in NCM lithium cells and is rated for 800 cycles to 80% capacity. It installs in the fridge's own battery compartment, so there is no separate unit to manage at camp. Power the fridge off before you install or remove the battery.
When the fridge powers on, the battery turns on with it. With a GLACIER Classic, switching the fridge off in the EcoFlow app also turns the battery off. If you use the power button or standby instead, the battery shuts down after a standby period you set in the app.
The USB-C port charges the battery at up to 100W (20V/5A) in about 4 hours and powers devices at up to 100W (5V, 9V, 12V, 15V or 20V at 5A). The battery's power button turns the USB-C port on or off on its own, whether the battery is in the fridge or not, so it doubles as a power bank for phones and laptops. A USB-C cable and adapter are not included.
Four indicator lights show the charge level in 25% steps, and the next light blinks while the battery charges. Separate blink patterns flag high or low temperature.
Campsites without hookups. Keep your GLACIER cold at a tent site or trailhead where there is no outlet and the vehicle is parked.
Beach days and tailgates. Carry the fridge away from the car and let the battery run it.
Device charging. Pull the battery out and use its 100W USB-C port to charge a phone, tablet or laptop.
Versus running the fridge on vehicle power. A car socket ties the fridge to the vehicle and its battery. The Plug-in Battery lets the fridge run on its own, wherever you carry it.
Versus a separate USB-C power bank. A standard power bank only charges devices. This battery powers your GLACIER fridge and also charges devices at up to 100W over USB-C.
This may be a good fit if
EcoFlow lists the Plug-in Battery for the GLACIER Classic 35L, 45L and 55L, and its manual shows how to install it in both the GLACIER Classic and the original GLACIER.
EcoFlow's manual lists two ways: connected to a GLACIER fridge, or through its USB-C port with a USB-C adapter. USB-C charging runs at up to 100W and takes about 4 hours.
Store it somewhere dry and well ventilated, ideally at 59°F to 95°F (15°C to 35°C). If it drops below 1% after use, charge it to 60% before storage. A deeply drained battery enters a sleep protection mode and needs a charge before use.
The EcoFlow GLACIER Plug-In Extra Battery gives your GLACIER fridge 298Wh of cordless power and adds a 100W USB-C port for your devices. If you have questions about fit or charging, the Outbound Power team is happy to help.
