The EcoFlow Portable Power Station Grounding Adapter is a purpose-built plug adapter that bonds neutral to protective earth in the socket so that appliances expecting a genuine earth reference, such as many gas boilers or electric vehicle chargers, will operate on a portable power station's floating AC output. Without such a bond most central heating boilers detect the floating network and refuse to start or throw a fault. The adapter accepts 100–240 V AC at 50/60 Hz and includes 5 V / 300 mA USB-C and 12 V / 300 mA network port pass-throughs.

• Bridges neutral and protective earth so appliances see a valid earth reference
• Enables central heating boilers to start and run normally from an EcoFlow power station during an outage
• Compatible with EcoFlow DELTA 3 Max, DELTA 3 Max Plus, DELTA 2 and DELTA 2 Max (DELTA Pro 3 already has this function built in)
• Not compatible with the DELTA 3 or DELTA 3 Plus, please check compatibility before ordering
• Wide AC input range of 100–240 V, 50/60 Hz for European mains
• Small pass-through USB-C and network port supplies for accessory use
