Best 2024 Generators for pass-through charging

#1 EcoFlow Delta 3 Plus Review
5.0

The station can charge while continuing to power connected devices, and both AC and solar pass-through performed reliably in testing.

Pros: rated output, peak output

Cons: 30-amp output, parallel operation support

#2 Bluetti Elite 200 V2
5.0

The station reliably powers connected devices while recharging, making it practical as a continuously connected backup source.

Pros: output stability, pure sine wave output

Cons: specification accuracy, startup reliability

#3 EcoFlow River 2
5.0

It can power connected devices while recharging, making it useful for continuous desk, router, and light backup duties.

Pros: surge capacity, output stability

Cons: dual-input charging, whole-home integration

#4 VTOMAN FlashSpeed 1000
5.0

The station can recharge from AC while continuing to power connected devices, which is useful before trips and during backup use.

Pros: inverter quality, power quality

Cons: Wi-Fi connectivity, weather resistance

#5 Enphase IQ PowerPack 1500
5.0

AC pass-through lets the station power connected loads while its battery charges from the grid.

Pros: rated output, output stability

Cons: runtime at full load, RV outlet

#6 Pecron E3600
4.7

Pass-through operation is a major strength, allowing loads to run while AC, solar, or generator power replenishes the battery.

Pros: power output, rated output

Cons: output stability, voltage regulation

#7 EcoFlow River 3
4.5

The unit can power devices while charging and works well as a continuously connected backup source.

Pros: noise level, idle noise

Cons: self-discharge rate, air travel suitability

#8 Jackery Explorer 1000 V2
4.5

Devices can keep running while the station recharges, a valuable outage feature, though very heavy loads reduce incoming charge speed.

Pros: rated output, peak output

Cons: standby power loss, specification accuracy

#9 AFERIY P280
4.5

The station can power devices while charging and can pass grid power directly through in UPS use. Heavy AC loads may shut down the inverter while DC and charging continue.

Pros: rated output, peak output

Cons: app connectivity, voltage regulation

#10 EcoFlow Delta Pro Ultra
4.0

Pass-through behavior is usually a strength, with bypass operation allowing simultaneous charging and output. One test found an important exception: AC outlets were lost while charging from 240V.

Pros: power quality, simultaneous device support

Cons: battery percentage accuracy, firmware updates

#11 Anker Solix F3800
1.9

The original F3800’s biggest functional limitation is AC pass-through: 240V and part of the 120V bank are disabled while charging from AC. Solar charging is far more flexible and can...

Pros: rated output, output stability

Cons: car charging speed, USB-A ports
