The short version: the Anker SOLIX F3000 is the one built around a 30-amp RV. Its TT-30R outlet is rated 120V, 30A and 3,600 W, the full rating of a 30-amp pedestal, and at 91.5 lb it is the lighter of the two. The F3800 Plus is the bigger home-and-RV unit: 3,840 Wh, 6,000 W at 120V or 240V from one box, more solar input and far more room to expand, but its TT-30R tops out at 3,000 W and it weighs 136.7 lb. Here is the detail, using Anker's own figures.

The 30-amp outlet is the big difference
A 30-amp RV pedestal supplies one 120V leg at 30 amps, which is 3,600 W (120 × 30). The F3000's TT-30R matches that on paper: Anker rates it at 120V, 30A and 3,600 W. The F3800 Plus's TT-30R is rated 25A and up to 3,000 W, so you have about 600 W less headroom for the coach.
That matters most for the rooftop air conditioner. Anker's RV AC sizing guide puts a 13,500 BTU unit at about 1,300–1,800 W running and 2,800–3,500 W to start. The F3000's TT-30R rating sits above the top of that start range, and the station lists 7,200 W of surge, although Anker does not publish a separate surge figure for the TT-30R itself. The F3800 Plus's 3,000 W TT-30R sits inside that start range, so a hard-starting unit may trip it. Start-up draw varies by model, age and heat, so test your own AC before you rely on either. Our 30-amp RV guide covers staging loads on a station.
One F3800 Plus catch: while it is plugged into a 120V wall outlet, Anker says its TT-30R passes through only up to 1,440 W and the L14-30R is off. Unplug it from the wall to get the full 3,000 W.
240V: one box or two
The F3800 Plus gives you 240V from a single unit through its L14-30R twist-lock, up to 6,000 W. Anker notes that the 240V output cannot be used while the unit is charging from 120V AC.
The F3000 is 120V only. Anker's answer for 240V is to pair two F3000s with the Double Voltage Hub for 240V, 30A and 7,200 W, sold together as the 2× F3000 + Double Voltage Hub kit (6,144 Wh). For most travel trailers 240V doesn't matter; for a house well pump or a 240V dryer it does.
Recharging
- Wall outlet: both take 120V at up to 15A from a standard household outlet; Anker lists 1,800 W for the F3800 Plus.
- Generator: Anker says the F3000 works with most 120V gas generators that have a TT-30 plug or adapter, charging at up to 3,600 W while it keeps powering your loads, and quotes a full AC recharge in 80 minutes. The 120V Generator Input Adapter makes that connection. With Anker's 240V Generator Input Adapter, the F3800 Plus passes up to 6,000 W from a 240V generator through to its outlets, and Anker rates generator charging at 3,300 W for the station alone or 6,000 W with an expansion battery. Anker says the adapter supports a single F3800 Plus only.
- Solar: up to 2,400 W on the F3000 and 3,200 W on the F3800 Plus. Anker's F3000 FAQ gives two examples: up to four 400 W panels in series on the high-voltage input for 1,600 W, and two 400 W panels in parallel on the low-voltage input for 800 W.
- While you drive: Anker sells the F3000 with its Alternator Charger, and so do we as the F3000 + Alternator Charger bundle. Anker doesn't publish an F3000 alternator charge time on the pages we checked; the Alternator Charger guide covers what it does publish.
Expansion
The F3000 takes up to three BP3000 batteries, for 12,288 Wh on one station. We sell it with one, two or three batteries already paired, up to the F3000 + 3× BP3000 (12,288 Wh).
The F3800 Plus takes up to six BP3800 batteries of 3,840 Wh each, which works out to 26,880 Wh with the station. Each BP3800 weighs 72.8 lb, so a big bank is a fixed install, not something you carry. We stock the BP3800 singly and in packs of two to six, such as the BP3800 2-pack.
How long each one runs
For planning we assume about 85% of rated capacity reaches your appliances after inverter losses. That is our estimate, not Anker's. Hours = Wh × 0.85 ÷ watts.
| Load | F3000 | F3800 Plus |
|---|---|---|
| Usable (planning) | about 2,611 Wh | about 3,264 Wh |
| CPAP, 40 W | about 65 h | about 82 h |
| Fridge, 100 W continuous | about 26 h | about 33 h |
| Microwave or kettle, 1,000 W | about 2.6 h | about 3.3 h |
| 13,500 BTU AC running, 1,300–1,800 W | about 1.5–2 h | about 1.8–2.5 h |
| Same AC, fully expanded (12,288 Wh vs 26,880 Wh) | about 5.8–8 h | about 12.7–17.6 h |
A real fridge cycles, so it uses less than a constant 100 W. The table is the cautious, always-on case.
Which one for your rig
- 30-amp travel trailer, and you want the most out of the shore cord: the F3000, for its 3,600 W TT-30R and lighter weight.
- One unit for the RV and the house, with 240V loads at home: the F3800 Plus.
- Long off-grid stays with a big battery bank: the F3800 Plus, which expands to more than twice the F3000's ceiling.
- You want 240V but like the F3000's TT-30R: two F3000s and the Double Voltage Hub, if you have room for two units.
If the station will also back up your house, read Anker SOLIX home backup: transfer switch, Smart Home Power Kit or Power Saver Kit before you buy. For the smaller stations, see which Anker SOLIX power station for an RV.
FAQ
Can the F3000 run a whole 30-amp RV?
Its TT-30R is rated at the same 3,600 W as a 30-amp pedestal, so on paper it can supply the full service. Capacity is the limit: about 2,611 Wh usable by our estimate, which runs a rooftop AC for roughly 1.5 to 2 hours.
Does the F3000 have 240V?
Not on its own. Anker says the F3000 provides 120V only, and that two F3000s connected with the Double Voltage Hub give 240V.
Which is easier to move?
The F3000, at 91.5 lb against 136.7 lb for the F3800 Plus. Both roll on wheels.
Where do they ship from?
Both ship from our warehouse in Upland, California, to the lower 48 states, with Anker's 5-year warranty. See the full Anker SOLIX range.
