ALLPOWERS R1500 vs R2500
Choose R1500 for portability and lower cost; choose R2500 for nearly twice the energy and stronger appliance output.
This is primarily a portability-versus-runtime decision.
Both use fast-charging LFP platforms, but R2500 is the more capable backup system.
R1500 for Mobility; R2500 for Backup
R2500 is the better long-term home and RV choice.
Comparison Verdict
Buy R1500 for regular transport. Buy R2500 when runtime matters more.

Runtime
R2500 stores about 75% more energy, making it substantially better for refrigerators and multi-day use.
Output
R2500 adds 700W of continuous output and better supports simultaneous kitchen or tool loads.
Portability
R1500 is easier to transport and store, making it better for frequent camping.
Who Should Buy Each?
Buy R1500
For lower weight and cost.
Buy R2500
For longer runtime and larger loads.
Choose R1500 for Camping
Easier transport.
Choose R2500 for Home
More energy.

Neither is native split phase.
Frequently Asked Questions
Who should buy R1500 or R2500?
Buy it when ALLPOWERS capacity, charging speed, solar input and expansion pricing match your real loads.
Who should skip R1500 or R2500?
Skip it when the lowest weight, broad retail support or native 240V matters more.
How should runtime be estimated?
Multiply watt-hours by roughly 0.80 to 0.90 for practical AC energy, then divide by average load watts.
Can ALLPOWERS run a refrigerator?
R1500 and larger models can generally run refrigerators when compressor startup remains within surge limits.
Can third-party solar panels be used?
Yes, when voltage, current, polarity and connectors remain within the exact MPPT limits.
Does ALLPOWERS support UPS use?
Many R-series models advertise about 15ms transfer, but sensitive equipment should be verified by exact model.
How long do the batteries last?
Current LFP R-series models generally claim more than 3,500 cycles to about 80% capacity.
Are expansion batteries universal?
No. B1000 and B3000 serve different station families and model revisions.
How should the station be stored?
Keep it cool, dry and ventilated and follow manufacturer charge-maintenance guidance.
What is the most common buying mistake?
Assuming every R-series model has the same expansion, solar and charging limits.
Which lasts longer?
R2500.
Which is easier to carry?
R1500.
Which has more output?
R2500.
Can they share batteries?
Verify exact revision before assuming compatibility.
