Shared DNA

What they have in common

If you only need big portable capacity and split-phase 240V, either unit covers the core job.

Capacity & output

Both: 3,840Wh, 6,000W rated / 9,000W peak, 120V/240V — serious camp, jobsite, or partial-home backup when sized correctly.

Expandability

Same BP3800 family: +3,840Wh each, up to 6 extras (23.04kWh total). MAP $1,799.99 per expansion.

Size & AC wall charge

Identical footprint (27.6″ × 15.3″ × 15.6″) and 1,800W / 120V AC input (~2.67 hours to full).

Key differences

Where F3800 Plus pulls ahead

1. Solar input — wider voltage, more watts

F3800

11–28V⎓10A and 28–60V⎓27A paths; 2×1,200W Max (2,400W class total). Size arrays carefully to those voltage windows.

F3800 Plus

11–165V⎓17A with 2×1,600W Max (3,200W class). Better match for coach roof solar or a larger parked array.

2. EV vs RV outlet — 14-50 vs TT-30R

This is one of the biggest practical differences. Neither unit is a dedicated wallbox EV charger, but the outlet on the station decides what you can plug in directly.

F3800 — better for EV-style plugs

Keeps a NEMA 14-50 receptacle — the same style plug many portable Level-2 EVSE units and large appliances use — plus L14-30 and 6× AC.

F3800 Plus — better for RVs

Replaces the 14-50 with a NEMA TT-30R (standard 30A RV receptacle), plus L14-30 and 6× AC. Built for Class C / campground hookups — not a built-in EV outlet.

3. 240V fuel generator charging

F3800

No 240V fuel-generator charging on Anker’s board.

F3800 Plus

Yes — charge from a 240V fuel generator when solar and shore power are not enough.
