Anker SOLIX F3800 Plus vs EcoFlow DELTA 3800 Gen4

The Anker SOLIX F3800 Plus is the stronger pick for whole-home backup and RV use. It outputs 120V/240V at 6,000W continuous and 10,200W peak, takes 3,200W of solar, and expands to 26.9kWh with six batteries. The EcoFlow DELTA 3800 Gen4 is far lighter at 67.5 lb, has a sub-10ms UPS transfer time, and is easier to carry and store. Owners of the Anker praise its quiet running and build; the EcoFlow is the better fit when portability and fast UPS switching matter more than raw output.

  • Choose the Anker SOLIX F3800 Plus if you need 240V output, whole-home or RV power, and the largest expansion capacity.
  • Choose the EcoFlow DELTA 3800 Gen4 if you want a lighter, more portable station with fast UPS switching for sensitive electronics.

What reviewers say

Anker SOLIX F3800 Plus

  • 5 / 511 ratings

Only 11 ratings so far, all 5 stars, so feedback is thin. Buyers praise the output, the quiet running and the RV-ready ports.

What people mention
  • OutputPraisedOwners say it powers heavy appliances and whole circuits at 120V/240V.
  • NoisePraisedBuyers describe it as quiet, even under load.
  • RV portsPraisedThe TT-30R port is called out as a good fit for RV hookups.
  • WeightCriticisedIt is heavy and awkward to carry, so it suits a fixed spot.

EcoFlow DELTA 3800 Gen4

Owners of the DELTA 3800 line praise the big LFP capacity, strong surge handling and fast solar charging, and many use it as a home backup unit. The main complaints are weight and size, plus the cost of expanding to the full 12kWh.

What people mention
  • CapacityPraisedOwners like that 3,763Wh covers long outages and expands to 12kWh.
  • WeightCriticisedAt 67.5 lbs it is hard to lift and move without help.
  • Surge powerPraisedThe 7,200W surge starts motors and pumps that stall smaller stations.
  • Solar inputPraisedUp to 2,000W of solar recharges it quickly on sunny days.

Questions and answers

Which is better for running a whole house?
The Anker. Its 6,000W continuous output, 240V support and 26.9kWh expansion cover central AC, well pumps and dryers. The EcoFlow tops out at 3,600W and 120V.
Which is easier to move around?
The EcoFlow. At 67.5 lb it can be lifted by one person. The Anker weighs 136.7 lb and relies on its wheels.
Which is better for a home office or PC?
The EcoFlow. Its under-10ms UPS transfer keeps computers and networking gear running through outages. The Anker is not rated as a UPS.
Is the Anker worth stepping up to over the EcoFlow?
Yes if you need 240V appliances, RV TT-30R hookups or expansion past 12kWh. If you only run 120V loads and move the unit often, the EcoFlow is the better fit.
Which lasts longer?
Both use LiFePO4 cells. Anker rates its battery at 3,000 cycles and backs it with a 5-year warranty. EcoFlow does not publish a cycle count for this model.
