Battery swap in the parcel locker.
Swap Module turns every parcel locker into a swap-and-go point for couriers. The battery waits where the courier already stops for a parcel — no detour, no waiting for a charge.

Europe, connected.

For fleets that count minutes
Last-mile operators
Couriers swap while collecting a parcel, so charging breaks disappear from the shift plan.
Q-commerce and food delivery
Short orders, many starts. A 30-second swap keeps riders moving through peak hours.
Parcel locker networks
A new energy service on existing lockers — without building separate swap points.
Three steps at the locker
- 01
Stop for the parcel
The courier pulls up to a locker they already had on the route.
- 02
Open the battery slot
Unlock the slot in the app, leave the empty battery, take a charged one.
- 03
Ride on
The empty battery charges under supervision while the courier returns to deliveries.
Concrete gains instead of downtime
Swap in 30 seconds
Seconds at the locker instead of hours on a charger.
Zero detours
The energy point overlaps the logistics point, so the route doesn't grow.
Dense network from day 1
You use the partner's existing locker density instead of building your own points.
No street works
No new poles, no trenching, no site permits.
24/7 outdoor operation
IP54 housing works in rain, frost and heat, with no technician on site.
Controlled charging
Batteries charge on managed profiles instead of random chargers in couriers' flats.
Fewer asset losses
Batteries stay in the company loop rather than at a courier's home.
Fleet data
Every swap is logged: who, when, which battery and in what state.
Let's work out how many courier hours you recover by swapping instead of charging.
Versions
Two ways to power. One ecosystem.
Multi-range charger with the O-Plug smart connector
One connector fits 95%+ of batteries on the market. A single charger inside the device serves batteries from many manufacturers — no adapters, no hardware swaps.
When: mixed fleet, sharing, public points
Bring Your Own Charger — your battery, your charger
Connect any battery with its own original charger. Mi.City provides the safe space, power, monitoring and access control — you change nothing in your equipment.
When: uniform fleet, manufacturer warranty requirements, fast rollout

A Warsaw q-commerce operator integrated Swap Module with the local parcel locker network. Couriers swap a battery at their natural parcel pickup point, with no charging detour to plan.
Frequently asked questions
No. The O-Plug version uses a multi-range charger with a smart connector, while BYOC lets you plug in your own batteries with their original chargers.
