The package is part of the comparison
| Listing detail | Selected bundle |
|---|---|
| ASIN | B0FR8VK9B8 |
| Observed price | $1,379.00 |
| Stored energy | 2,048 Wh |
| Rated AC output | 2,400 W |
| X-Boost headline | Devices up to 3,400 W, subject to compatibility |
| Listed contents | DELTA 3 Max, one 400W panel, AC charging cable |
This is DELTA 3 Max, not Max Plus or an older DELTA Max. A cheaper station-only offer is not an equivalent bundle.
Watts and watt-hours answer different questions
Output watts describe the load the station can supply at a moment; watt-hours describe stored energy. Dividing 2,048 Wh by a constant 100 W gives 20.48 hours as an idealized calculation before conversion losses and other consumption. Real runtime is lower and depends on the device.
A refrigerator or tool may cycle or draw startup power, so simply dividing by a label value can be misleading. Measure or obtain the appliance’s actual requirements and compare them with the exact station’s limits.
Do not substitute X-Boost for rated output
The seller headline references 3,400 W in X-Boost mode, while the product overview gives 2,400 W output. EcoFlow’s product information distinguishes rated AC output from the higher supported-device figure. We would use the rated figure as the starting point for normal load planning.
X-Boost compatibility depends on the appliance and operating conditions. It should not be treated as a universal 3,400 W normal-output rating. We have not tested voltage behavior, overload response or any specific appliance on this unit.

Brand / retailer image · Product source ↗A 400W panel is not 400W around the clock
The included panel rating is a test-condition maximum, not guaranteed harvest in your location. Sun angle, weather, shade and placement change charging power. Confirm compatible cables and the exact panel type in the selected package before ordering.
An ideal 2,048 ÷ 400 calculation is 5.12 hours, but that ignores losses, changing sunlight and charging behavior. It is not a forecast of full solar charging time. The listing’s fast AC charging statement is also a separate claim from solar charging.
View full image ↗The solar-time illustration uses a 500 W input condition. It is not a charging-time promise for the included 400 W panel, which also depends on real sunlight and orientation.
Brand / retailer image · Product source ↗Backup use needs more than a transfer-time number
The page advertises a transfer time below 10 ms. We have not tested it with sensitive equipment, and that specification alone does not qualify the station as a guaranteed backup for medical or life-support equipment. Confirm compatibility with the equipment manufacturer for critical uses.
For ordinary portable use, check total simultaneous load, outlet needs, placement and recharge access. Do not improvise a connection to household wiring; fixed home integration requires the appropriate equipment and qualified installation.
Value and the ownership questions
The battery chemistry is listed as LiFePO4 and the seller advertises a five-year service arrangement. Confirm warranty terms, battery-service options and the portability of both the station and panel. A long lifespan claim is not a measured lifespan for your unit.
This bundle makes sense when you need both the station and solar panel and can place the panel effectively. If you mainly recharge from a wall outlet, compare the station-only cost. We have not tested runtime, charging speed, fan noise or long-term capacity loss.
View full image ↗The outdoor scene gives scale to a roughly 44.7 lb station. Consider lifting and transport with the separate solar panel, not just tabletop dimensions.
Brand / retailer image · Product source ↗Before you buy
Is a solar panel included?
Yes. This exact listing states one 400W panel, plus the station and AC charging cable.
Is 3,400 W its normal rated output?
The reviewed sources distinguish 2,400 W rated AC output from X-Boost support for certain higher-rated devices.
