How to start a power bank sharing business

Start with the venue, not the station

A shared power bank business is a route business. The unit of work is not a cabinet, it is a place people stand with a phone at twenty percent and time to kill. Before any supplier conversation, write down three venue types you can reach in one afternoon: a bar, a restaurant with a queue, a salon, a clinic waiting room, a gym floor. If you cannot reach them, the hardware will not help.

The second thing to settle is the venue deal. There are three shapes. A fixed rent per month, a revenue share, or a fee per pack. All three work, but they have different failure modes: fixed rent punishes a site that turns out quiet, a revenue share punishes a site that takes a cut and promotes nothing, and a fee per pack only works where the venue hands the pack over itself. Get the shape and the percentage in writing before you order, because it moves the payback more than the price of the cabinet does.

Step one: count the busiest hour

Daily footfall is the wrong number. What sizes the station is how many guests are holding a pack at the same moment. Stand in the venue at its busiest hour, on its busiest night, and count:

• People who are staying longer than thirty minutes, because a short visit is not a rental.
• People who are visibly on a phone, which is a rough but honest proxy for battery anxiety.
• People holding a bag or a coat, because they will not want to stand next to a socket.
• Seats near a power socket, and whether the venue already has one.
• The time a guest actually waits: a table queue, a fitting room, a pharmacy counter.

Two counts on two different days beat one estimate from the venue owner. Write the number down with the hour it was taken.

Step two: choose the format

The format follows the count and the counter. A five slot counter unit is the cheapest way to test a site. An eight slot station is the volume format for a bar or a restaurant with a real queue. A 24 to 48 slot cabinet only makes sense where the peak hour empties eight bays, and a stackable unit belongs at an event, not in a lobby.

Step three: price the rental

The tariff is a time ladder: a base fee for the first hour, a step for each hour after it, and a daily cap. The cap is the part that matters. Without it, a guest who forgets a pack for three days owes more than the pack is worth, and the guest who cannot face the bill abandons it. With it, the worst case is predictable and the pack comes back.

• Set the first hour low enough that a guest says yes without thinking.
• Set the cap at roughly the price of losing a pack, so returning stays rational.
• Charge a deposit only where the market expects one, and print it on the signage.
• Keep one tariff per country. Multiple currencies in one venue confuse the staff first.

Step four: decide who settles the money

A card terminal, a QR payment page or a wallet app each settle differently. The terminal belongs to an acquirer that has to board your business in your country; the QR page belongs to a payment provider that has to support your currency. Neither is a hardware setting. Confirm which combination is certified for your market before the cabinet ships, because a station with a terminal your acquirer will not board cannot take money at all.

Ask the supplier for the terminal list and the settlement terms in writing. A supplier who answers with a brand name and no certification has not answered.

Step five: build a route, not a site

One cabinet in one bar is a hobby. Three stations within a fifteen minute walk of each other is a route: one person can restock all three, a failed unit takes a third of the capacity offline instead of everything, and a guest can return a pack at a different door than the one they took it from. The return network is the product. Add stations along a route you already walk.

Step six: run the first month as a test

The first month produces the numbers that decide the second order: rentals per day, failed returns, packs swapped, and the hour of the day the cabinet empties. Compare them to the count you made before the order. If the cabinet empties at the peak, order the next size up. If it never empties, the venue was the wrong one, and a second cabinet in the same place will not fix it.

The first order should contain four things: the station, spare packs, the spare part list with prices, and the software terms in writing. The spare part list is the one most first orders forget, and it is the one that decides what month seven costs.
