EcoFlow River 3
2.0
Owners describe warranty or RMA steps as inconvenient when hardware faults appear.
Runtime at full load
Enphase IQ PowerPack 1500
1.0
Running near 1,500 W drains the battery in under an hour, leaving little headroom for sustained heavy use.

RV outlet
Enphase IQ PowerPack 1500
1.0
It lacks the higher-amperage RV connection some campers need, so direct RV powering may require a different station.

Self-discharge rate
Enphase IQ PowerPack 1500No score yet
EcoFlow River 3
1.0
One owner reported severe charge loss while the unit was switched off, making standby storage unreliable in that case.
UPS functionality
Enphase IQ PowerPack 1500No score yet
EcoFlow River 3
4.1
For routers, modems, computers, and network gear, UPS performance is usually seamless and excellent. A smaller but important group reports random AC shutdowns or failed transfers.
Whole-home integration
Enphase IQ PowerPack 1500
2.8
The Enphase branding can be misleading: it fits naturally into the company’s app ecosystem but does not directly connect to rooftop solar or replace a true whole-home battery.

Battery percentage accuracy
Enphase IQ PowerPack 1500No score yet
EcoFlow River 3
2.8
One owner questioned whether the displayed runtime estimate would hold through a full discharge.
Charging input compatibility
Enphase IQ PowerPack 1500No score yet
EcoFlow River 3
1.9
Charging-source flexibility is a weak spot: the unit cannot recharge through USB-C, may require specific solar cabling, and rejected one vehicle’s stepped-sine AC outlet.
Dual-input charging
Enphase IQ PowerPack 1500No score yet
EcoFlow River 3
2.0
Charging inputs cannot be combined, so there is no simultaneous wall-and-solar or multi-source charging.

There is no wireless charging pad, a minor omission that some users notice and others consider unnecessary.
Performance
Cold-weather performance
Enphase IQ PowerPack 1500No score yet
EcoFlow River 3
2.3
Cold weather can slow charging and reduce LFP performance, so winter users should temper expectations.
Full-load noise
Enphase IQ PowerPack 1500No score yet
EcoFlow River 3
4.8
Even during charging or near rated output, it remains unusually quiet for a power station.
