one side unscoredWhat EcoFlow DELTA Pro and ALLPOWERS R4000 owners report
Independent sources, scored for each model. DELTA Pro on 5 of five, R4000 on 4.
The ALLPOWERS R4000 reading covers the whole brand.
What they say
EcoFlow DELTA Pro
- Six DELTA Pro owners in r/Ecoflow_community and r/RVLiving reported seven smoke events between May 2023 and July 2026, including a replacement unit that smoked after the first one had (February 2026, 154 comments) and a unit that smoked at a 30 W load (February 2026).
- Four owners describe running through several replacement units with error codes, and one unit was bricked by a firmware update (January 2026).
- Three owners praise it for RV air conditioning and long vanlife use.
ALLPOWERS R4000
- No owner thread in an independent subreddit names the R4000, so this reads the brand.
- In r/SolarDIY an R2500 owner said ALLPOWERS told him the B3000 expansion battery connects only to the R3500 in the US (2024); in r/GoRVing an owner's R1500 clicked above 30 W of AC load and its app would not connect over Bluetooth or Wi-Fi, and a commenter said no one at ALLPOWERS answered email or phone (2024).
Both readings are about these exact models.
What they say
EcoFlow DELTA Pro
- CNET drew 3,328 Wh on AC, 92 percent of rated.
- OutdoorGearLab, which buys its test units, charged it at 1,412 Wh an hour, about 2.6 hours, and drew 2,950 Wh in its table and 3,060 Wh in its text, 82 to 85 percent (May 2025).
- StorageReview drew 3,000 Wh at a 350 W load and needed 4,180 Wh to recharge.
- TheSolarLab, which earns affiliate commission, found its own five-year-old unit at 84 percent efficiency in 2026 but struggling to hold maximum output.
ALLPOWERS R4000
- Vantour, a French van-life site that passes on an ALLPOWERS discount code and links to ALLPOWERS' store, put a full wall charge at about 4 hours, an EV charging-station charge at about 2 hours and 400 W solar at about 8 hours, found the fans quiet under heavy load, and noted app connection problems some owners report and no car charging cable in the box (July 2024).
YouTube
+1 EcoFlowBoth readings are about these exact models.
What they say
EcoFlow DELTA Pro
- EEVblog2 measured it at a 1 kW load and found its on-screen percentage non-linear (February 2023, about 25,000 views).
- HOBOTECH's technical review is labelled as a paid promotion and carries an EcoFlow code (July 2021, about 177,000 views), and Will Prowse discloses that every video includes paid promotion or free product (2021, about 618,000 views); neither published a usable figure.
ALLPOWERS R4000
- Eric Hernandez, which passes on an ALLPOWERS promo code and earns commission on linked products, drained the R4000 V3 until the inverter shut off with 5 percent still showing and load-tested it toward its 3,600 W rating (February 2025, about 31,200 views).
- A March 2023 review titled "DON'T BUY THE ALLPOWERS R4000 Power Station Without Watching This First!", on a unit and 400 W panel ALLPOWERS sent with a discount link, backfed the house's 120 V circuits through a transfer switch, charged at about 1,540 W from the wall with 270 W of solar, and ran a 1,200 W heater for 2 hours 10 minutes before shutoff at 5 percent.
- Chef Prepper, which carries a 12 percent ALLPOWERS code, said the 2,000 W fast charge needs a 220 to 240 V circuit (March 2025).
Amazon
+5 EcoFlowBoth readings are about these exact models.
What they say
EcoFlow DELTA Pro
- The DELTA Pro listing (B0C1Z4GLKS) reads 4.6 from 669 ratings, 85 percent five-star and 6 percent one-star, pooled across its panel and extra-battery styles, and EcoFlow is not its current seller.
- Amazon's review tags are positive on performance (75 of 80 mentions) and battery life (34 of 42), and negative on durability (11 of 20), mostly a breaking pull handle.
ALLPOWERS R4000
- The station listing in ALLPOWERS' own Amazon US store (B0BRCLJ79Q), titled 3,456 Wh with a 1.2-hour charge, holds 3.2 from 15 ratings; its star split and review text sit behind sign-in.
