Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Permobil VoltPro (616270 / 616347) (341W surge).
| 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 × 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 — 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 × 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 — 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 C₂₀ 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. | |||||

Generator Insights
With 12000 watts of surge capacity, this system can handle typical startup loads for central air compressors, well pumps, and other motor-driven equipment common in residential settings. The 6000-watt continuous rating supports sustained operation of multiple high-draw appliances simultaneously. The 6144 Wh capacity provides meaningful runtime for essential circuits during grid outages.
This unit uses lithium iron phosphate (LFP) chemistry, known for stable thermal behavior in stationary storage applications. The system is designed with internal protections typical of grid-tied and off-grid battery platforms. Source: EcoFlow DELTA Pro Ultra User Manual (manufacturer documentation).

Spec-Based • No GuaranteesTechnical Breakdown
Running range: 121W to 341W depending on charger amperage and battery chemistry. Surge: Equal to running watts (switch-mode chargers have no inrush). Voltage: 120V AC. Wheelchair chargers are steady-state loads with no cycling or surge events.
Expected Behavior
Estimated runtime: ~12.6h. Typical charging session is 8 hours overnight. Daily energy consumption ranges from 968 Wh (3.5A lithium) to 2,728 Wh (10A lead-acid). Actual draw tapers as batteries approach full charge, so real energy consumption is lower than worst-case estimates.
Field Note
Wheelchair chargers are medical devices — always maintain a backup power source. Pure sine wave output is recommended. Verify your power station can sustain the full charge duration without thermal shutdown. The charger amperage printed on the label is DC output current, not the AC draw from the wall.
