In a top-floor walk-up, every kilo matters — you have to carry the thing up three or four flights, and move it out again at the end of the lease. Here is how to pick a power station you can actually lift.
The short answer
For a walk-up, weight is the deciding spec. Pick the lightest unit that meets your needs: the Jackery Explorer 300 Plus (3.75 kg) for essentials, the EcoFlow RIVER 2 Pro (7.8 kg) for more, or the Jackery Explorer 1000 v2 (10.8 kg) if you need a full 1 kWh. Skip the 16 kg+ units — they are miserable on stairs.
Weight vs capacity for walk-ups
| Unit | Weight | Capacity | Stairs verdict |
|---|---|---|---|
| Jackery 300 Plus | 3.75 kg | 288 Wh | One-hand easy |
| EcoFlow RIVER 2 Pro | 7.8 kg | 768 Wh | Easy |
| Jackery 1000 v2 | 10.8 kg | 1070 Wh | Manageable |
| Bluetti AC180 | 16.4 kg | 1152 Wh | Two hands, a chore |
