Wh
4,096 WhFrom the manual
Enough for a 60 W fridge for about 2 days, or a CPAP for about 4 days.
W
4,000 WFrom the manual
Microwave, kettle, most kitchen gear.
Surge
8,000 WFrom the manual
Short bursts for motors starting, like a fridge compressor or a pump.
Voc
XT60 (High-PV): 30 to 150 V
XT60i (Low-PV): 11 to 60 V
From the manual
The 2 inputs take different voltages, so check which one your panels go into. Your panels, wired up, must stay inside this range even on a cold morning. The checker does the math.
Imp
XT60 (High-PV): 15 A
XT60i (Low-PV): 20 A
From the manual
Over this, the station simply caps what it takes. You lose watts, nothing breaks.
MPPT
2,600 W (1,600 W + 1,000 W)From the manual
From empty to full in about 2.5 hours of good sun at 70% of rating.
Solar portplug
XT60 (High-PV), XT60i (Low-PV)From the manual
The plug on the station. Panels with a different plug need an adapter cable; we list it in the checker.
LiFePO4
LiFePO4From the manual
Long-life chemistry, suited to daily solar use. Check the manual for the exact cycle rating.

Wheels or two people. Not a grab-and-go unit.

Solar panels that work with it

Checked against the 30 to 150 V and 11 to 60 V input ranges and the 15 and 20 A current caps, on a 20F morning. Change panels, count and temperature in the full checker.

Watch out for

Things in the manual that catch new owners.

01The two solar inputs are different. High-PV takes 30 to 150V, Low-PV takes 11 to 60V. A single small panel is too low for High-PV and will not charge there.
02EcoFlow's manual: panel voltage rises in cold weather, so keep a margin below the limit when wiring in series.
03For parallel wiring you need Y-branch (T-branch) solar cables.

Compared with

Side by side with the same-size station from other brands.
