Why I ordered the R2500 V2#
Ordered in November to replace my tired Bluetti EB150. 4 months of full-time vanlife across Pyrenees and northern Spain. Goal: solid LFP station for compressor fridge + Nespresso + work laptop, without the Delta 2 Max budget at €1199-1207 on EcoFlow EU.
Real V2 specs#
1920 Wh LFP rated 4500+ cycles to 80% capacity (new V2 chemistry — older R2500 was 3500 cycles). 2500W continuous inverter, 5000W peak on resistive loads. At €899 on Awin = €0.469/Wh. Competing Delta 2 Max at 2048Wh = €0.585-0.589/Wh. On paper, R2500 V2 is 20-25% cheaper per Wh. Double-check Awin feed when ordering, prices shift.
Ports (watch for rumors)#
4× AC outlets (2500W total), 2× USB-C PD 100W (200W combined), 4× USB-A 18W, 2× DC5525 12V, 1× 12V car socket, 1× XT60 solar input. NO Anderson SB50 on the V2 — don't trust sloppy listings, I checked the manual, Amazon spec, iallpowers.eu photos. For alternator charging via Victron Orion-Tr Smart 30A DC-DC, you feed the 14.4V output straight into the XT60 solar input (12-150V range). Clean, no hackery.
15ms UPS: tested real#
My inverter compressor fridge never hiccuped on mains-to-battery handoffs when switching between shore and battery mode. Hidden spec for inverter compressors is 20ms max dropout — R2500 V2 at 15ms clears it comfortably.
1000W MPPT solar, 12-150V#
Big jump over sub-€1000 stations: 1000W max MPPT, 12-150V, 20A. Ran 4× 200W panels in series (~90V Voc total, inside the window) without optimizer, handled it. Clear day = 12% to 95% recharge in 3h20.
Honest weak point: the app#
ALLPOWERS app is NOT at EcoFlow app level — mediocre Bluetooth latency, basic consumption graphs. For serious monitoring I add a Victron BMV-712 shunt in parallel on the house battery. Advertised "2-5 Year" warranty on iallpowers.eu is vague — contact support before buying.
Verdict#
For sub-€1000 van LFP station, strongest 2026 proposition if you accept a mediocre app. If budget is open and you want polished ecosystem, Delta 2 Max still wins on UX.
Expert tip
To combine solar + alternator on the R2500 V2: only one XT60 input. Use a manual XT60 switch or Schottky diode combiner (60V/40A) to isolate panels and DC-DC, or simply charge one then the other. Monitor combined voltage under 150V Voc.

12V Cable Sizing Guide
Use this professional reference table to select the correct gauge (mm²) for your cables. For 12V in a van, the maximum tolerated voltage drop is 3%. Always use multi-stranded flexible automotive wire.
| Current (A) | Round trip < 2m | Round trip 4m | Round trip 6m |
|---|---|---|---|
| 5A (LEDs, USB) | 1.5 mm² | 2.5 mm² | 4 mm² |
| 10A (Fridge, Pump) | 2.5 mm² | 4 mm² | 6 mm² |
| 20A (Heater) | 4 mm² | 10 mm² | 10 mm² |
| 50A (DC/DC Booster) | 10 mm² | 16 mm² | 25 mm² |
| 100A (Inverter) | 25 mm² | 35 mm² | 50 mm² |
Fuse Sizing
The fuse protects the wire, not the appliance. Always place it as close to the power source as possible (battery or busbar).
- Wire 1.5 mm² → Max fuse 10A
- Wire 2.5 mm² → Max fuse 20A
- Wire 4 mm² → Max fuse 30A
- Wire 6 mm² → Max fuse 40A
- Wire 10 mm² → Max fuse 60A

Frequently asked questions
Actual capacity of the R2500 V2?▼
1920 Wh of LFP (lithium iron phosphate), rated 4500+ cycles to 80% capacity per ALLPOWERS EU V2 listings. That's the new V2 chemistry — older R2500 was rated 3500 cycles.
Can I charge it from the van alternator?▼
Yes, via isolated DC-DC charger like Victron Orion-Tr Smart 30A. Feed the 14.4V DC-DC output directly into the R2500 V2's XT60 solar input (accepts 12-150V). NO Anderson port needed — R2500 V2 doesn't have one.
AC charge time?▼
About 1 hour to 80% per ALLPOWERS official spec. Full charge depends on mode (quiet vs fast) and typically takes longer.
Max solar input?▼
1000W max MPPT, 12-150V range, 20A. High-voltage panels in series possible (e.g., 4×200W in series ~90V Voc) as long as you stay under 150V Voc.
Does it have an Anderson SB50 port?▼
No. Despite what some listings suggest, the R2500 V2 does not have an Anderson SB50 port. For reference, the SB50 is an Anderson housing size rated up to 120A (UL) — the '50' is housing size, not current rating. R2500 V2 uses XT60 for solar and DC5525 for 12V outputs.
