What this unit is for
LiFePO4 and high inverter output at value pricing — the challenger that competes on chemistry and watts rather than on ecosystem.
Best suited to: Value buyers who care about chemistry and output more than ecosystem. Less suited to: Buyers who need a mature app, dealer support or resale value.
Multi-day backup, off-grid and whole-home loads.
Where to buy
A tracked retailer link appears here only when we have a resolved offer for this model. We do not send readers to a manufacturer store page we cannot attribute.
Safety: lithium power stations store a lot of energy. Follow PECRON’s charge, ventilation, and storage instructions. WattPicks does not certify electrical installs.

PECRON E3800LFP specs FAQ
What are the PECRON E3800LFP specs?
3.84 kWh capacity; 4.2 kW continuous AC; 87.3 lb; LiFePO4; listed at $1,299. 8 of 19 tracked specs are published by PECRON on the product page we read. List price is shown separately ($1,299).
How long does the PECRON E3800LFP last?
The vendor rates it for 3,500 cycles with LiFePO4 chemistry. Runtime on a given day is capacity divided by load (with inverter losses) — see our guide on how long a power station lasts.
Can the PECRON E3800LFP charge from solar?
Yes — PECRON publishes a maximum solar input of 3 kW. Ideal fill time is roughly capacity ÷ that input; real sun takes longer. See how long to charge with solar.
Is the PECRON E3800LFP good value?
At the published list price it works out to $0.34 per watt-hour. Compare that figure on our cost-per-watt-hour ranking rather than price alone.

Who buys this brand, and why
All models →Who it is for
- Value buyers who have learned to look for LiFePO4
- RV and off-grid users wanting high output cheaply
- Preparedness buyers comparing 240V-capable units
What they will pay extra for
- LiFePO4 and a stated cycle life
- Inverter output per dollar
- Expansion batteries priced fairly
Honest drawbacks
- Brand support and service are less established than the majors
- App and firmware polish is behind EcoFlow and Anker
- Independent long-term durability data is thin
- Frequent model churn makes like-for-like comparison harder
