| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Pride / UPG 24BC3500L-1 (24V 3.5A Lithium) | 121W | 121W | Safe | ~35.5h | Engineering Est. |
Show expert analysisTechnical: **Running load:** ~121W AC estimated from 101W DC output (28.8V ร 3.5A) at ~83% charger efficiency. **Surge:** ~121W (switch-mode charger, no inrush). **Voltage:** 120V AC (universal 100-240V input). This is a lithium-only charger for Go-Go Endurance scooters and Jazzy EVO Series 613 power chairs. Field note: This charger is lithium-only โ do not connect to lead-acid batteries. At 121W it is the lightest load in the set and compatible with virtually any power station above 200W continuous output. Verify pure sine wave output for medical equipment. Can I charge a lithium wheelchair battery with a portable power station? Only if your power source can supply at least 121W continuous at 120V. Lithium wheelchair chargers draw less than lead-acid equivalents and are well-suited to portable power, but always maintain a backup source for medical mobility equipment. | |||||
| Pride / UPG 24BC5000T-4 (24V 5A) | 180W | 180W | Safe | ~23.9h | Engineering Est. |
Show expert analysisTechnical: **Running load:** ~180W AC estimated from 148W DC output (29.6V ร 5.0A) at ~83% charger efficiency. **Surge:** ~180W (switch-mode charger, no inrush). **Voltage:** 120V AC (universal 100-240V input). Three-stage charge cycle with DOE-mandated 20-hour auto-cutoff. Field note: This is the most common charger size for standard power wheelchairs with Group 22NF or Group 24 lead-acid batteries. At 180W, a 1,500 Wh power station provides roughly 8 hours of charging โ enough for a full overnight cycle. How long can a portable power station run this wheelchair charger? Only if your power source can supply at least 180W continuous at 120V. A 1,500 Wh power station provides approximately 8 hours at full draw, sufficient for a complete charge cycle on most standard wheelchair batteries. | |||||
| Permobil VoltPro (616270 / 616347) | 341W | 341W | Safe | ~12.6h | OEM Manual |
Show expert analysisTechnical: **Running load:** 341W AC worst-case (300W max DC output at OEM minimum 88% efficiency). **Surge:** 341W (switch-mode charger, no inrush). **Voltage:** 120V AC only (110-126V tolerance range). This is a 10A charger designed for Permobil power wheelchairs with large battery banks (30-100 Ah at Cโโ rate). Field note: The VoltPro is the highest-draw wheelchair charger in this comparison. Most mid-range power stations (under 500W continuous) can handle it, but the energy demand is substantial. For a full overnight charge during an outage, budget at least 2,500 Wh of usable station capacity. Why does the Permobil VoltPro draw so much more than other wheelchair chargers? Only if your power source can supply at least 341W continuous at 120V. The VoltPro is a 10A high-current charger designed for large power wheelchair batteries (up to 100 Ah). It charges faster but demands more from the power source than standard 3.5A or 5A chargers. | |||||

With 24,000W surge capacity, this system can handle typical compressor startup events found in central air conditioners, well pumps, and refrigeration equipment. The 12,000W continuous rating supports sustained high-load operation across multiple circuits. At 6,144Wh usable capacity, runtime depends on connected load, but this configuration can support whole-home essentials during extended outages.
This unit uses LFP chemistry, a formulation widely recognized for thermal stability in residential backup applications. The manufacturer provides operational guidelines in their documentation, and users should follow all installation and grounding instructions.

Yes. The EcoFlow Delta Pro Ultra X provides 12000W running / 24000W surge. The Electric Wheelchair Charger needs 393W / 393W (including 15% buffer). That leaves 11607W of running headroom and 23607W of surge margin.
Approximately 12.6 hours, based on the Electric Wheelchair Charger's 341W draw and the Delta Pro Ultra X's 6144Wh capacity (70% usable after real-world losses).
With 1790W allocated to the Electric Wheelchair Charger, the Delta Pro Ultra X still has ~7469W of margin. These devices could run simultaneously:
Pro Tip for Medical Users: According to energy reports, turning off the humidifier on your Electric Wheelchair Charger can double your runtime. Using a DC cable instead of the AC plug is also recommended to avoid inverter inefficiency.
