Mango Power Power E sizing guide
First Mango Power entry — a 3.5 kWh, 3,000 W home-backup unit on CATL LFP cells rated 6,000+ cycles, expandable to 14 kWh with add-on batteries. Here's exactly what it runs, how long, and which outages it covers — computed, not marketed.
0-80% in 60 min AC (30A fast-charge cable); full in ~1.5 h · 100 lb · 5× AC, 8× USB, 3× DC · expandable with add-on batteries.
What the Power E runs — and for how long
| Appliance | Running | Runs it? | Approx. runtime |
|---|---|---|---|
| Refrigerator (modern) | 150 W (1,200 W surge) | yes | ~60 h |
| Chest Freezer | 100 W (1,000 W surge) | yes | ~90 h |
| CPAP Machine (no humidifier) | 40 W | yes | ~79 h |
| CPAP with Heated Humidifier | 60 W (95 W surge) | yes | ~66 h |
| Oxygen Concentrator | 350 W (600 W surge) | yes | ~9.0 h |
| Space Heater (1500 W) | 1,500 W | yes | ~2.1 h |
| Window AC (8,000 BTU) | 715 W (1,250 W surge) | yes | ~6.3 h |
| Window AC (12,000 BTU) | 1,100 W (1,800 W surge) | yes | ~4.1 h |
| Gas Furnace Blower (1/2 HP) | 800 W (2,350 W surge) | yes | ~7.9 h |
| Microwave (1000 W cooking) | 1,200 W | yes | ~2.6 h |
| Sump Pump (1/3 HP) | 800 W (1,500 W surge) | yes | ~20 h |
| Sump Pump (1/2 HP) | 1,050 W (2,150 W surge) | yes | ~15 h |
| Well Pump (1/2 HP) | 1,000 W (2,100 W surge) | yes | ~21 h |
Runtime uses each load's duty-weighted average draw against 90% of the rated capacity — conservative on purpose. Cyclic loads (fridges, pumps) run far longer than running-watts × capacity would suggest.

Common questions
What can the Mango Power Power E run?
With 3,000 W of continuous output and a 4,800 W surge rating, the Mango Power Power E runs refrigerator (modern), chest freezer, cpap machine (no humidifier), cpap with heated humidifier, oxygen concentrator, space heater (1500 w), and more. Its 3,506 Wh battery sets how long: a fridge for roughly a day, a CPAP for several nights.
How long will the Mango Power Power E run a refrigerator?
A modern refrigerator averages about 53 W (it cycles ~35% of the time), so the Mango Power Power E's 3,506 Wh runs one for roughly 60 h before recharging.
