The Simple Reason You Can Always Find a Phone Charger in China, and Why the Business Behind It Is Now Struggling
Anyone who’s spent time in a Chinese city has probably noticed something that takes a beat to register: you’re basically never more than a few minutes’ walk from a place to charge your phone. Not a wall outlet you have to beg a restaurant to let you use, but a dedicated kiosk sitting right there in the mall, the metro station, the noodle shop, even bolted onto streetlight poles in parts of Beijing. Scan a code, pull out a battery pack, walk away, drop it off wherever you end up. It sounds almost too convenient to be a real business, and yet it’s one of the more successful consumer tech industries China has produced, even if it’s currently going through a rough patch.
The system is called shared power bank rental, and it’s built around a simple loop. You find a rental cabinet, usually a small vending-machine-style unit sitting on a countertop or mounted to a wall, and scan its QR code using WeChat or Alipay. That opens a mini-program inside the app, you pay a small deposit or link your account, and the machine releases a portable battery pack, typically good for one or two full phone charges. You use it while you’re out and about, then return it to any cabinet from the same brand, not necessarily the one you rented from, whenever you’re done. It works almost exactly like a bike-sharing scheme, except the thing you’re borrowing fits in your pocket.
What makes this genuinely different from how most other countries handle public charging is the underlying assumption baked into the model. In much of Europe and North America, free USB ports or wall outlets show up in enough public spaces, airports, coffee shops, libraries, that a dedicated rental business struggles to find a market. China largely skipped that phase. Most public venues there never really built out free charging infrastructure the way Western airports and cafes did, so when smartphones became something people genuinely couldn’t function without, a market opened up almost by default for someone to fill that gap. The country that never built enough free outlets ended up building an entirely separate industry to solve the same problem, and it turned out to scale far more easily than free infrastructure ever would have.
The scale really is enormous. China’s shared power bank market has been running for roughly 11 years now, and current industry estimates put the number of active rental cabinets somewhere north of 7 million units nationwide, spread across malls, restaurants, metro stations, airports, hotels, convenience stores, and plenty of smaller venues most tourists would never think to check. A handful of major operators dominate the space, including Energy Monster, which trades on the Nasdaq and at one point controlled around 36 percent of the market, alongside Jiedian, which is now operated under Meituan, the food delivery giant that jumped into the business a few years back using the same QR-code, app-based playbook it built for bike sharing. Pricing is cheap enough that nobody thinks twice about it, typically a couple of yuan for every half hour of use, with most operators capping the daily charge somewhere around 30 yuan even if you hold onto the battery all day.
Some cities have pushed the idea even further. Beijing has been retrofitting streetlight poles in select neighborhoods with built-in power bank docks and wireless charging pads, meaning you don’t even need to seek out a dedicated kiosk in some areas, the charging point is already part of the streetlight you’re standing under. It’s a small addition, but it reflects how normalized the whole concept has become: charging infrastructure isn’t treated as a special amenity anymore, it’s closer to a utility, something cities are starting to weave into existing public fixtures rather than treat as separate hardware.
Here’s the part that complicates the otherwise tidy convenience story, though. Despite the sheer scale of the industry, it’s been having a genuinely difficult stretch financially. Energy Monster has reportedly faced internal boardroom disputes as the broader power bank rental sector has contracted, and the core problem is one investors apparently didn’t see coming clearly enough a few years ago: smartphone batteries and fast-charging technology from companies like Apple, Huawei and Xiaomi have improved fast enough that people simply need emergency charging far less often than they used to. What was supposed to become a habitual, everyday behavior has increasingly settled into something people only reach for occasionally, when their battery is genuinely critical, which undercuts the volume these rental businesses were built around. On top of that, the underlying economics of running these networks are brutal even before demand softens: operators typically hand over 50 to 70 percent of rental revenue to the venues hosting their cabinets just to secure placement, on top of battery depreciation costs that eat into margins from the other direction.
Safety has become a live concern too. Anker Innovations, the well-known consumer electronics brand and one of the biggest names in portable charging generally, recalled 1.15 million power banks globally after investigators traced battery defects back to a shared supplier that had outsourced production to a factory in Jiangxi, a reminder that an industry built around millions of battery packs constantly cycling through public hands carries real manufacturing and safety stakes alongside the convenience.
None of that changes the basic experience of actually being in China and needing a charge, though. The system still works exactly as advertised: find a cabinet, scan a code, grab a battery, keep moving. It’s just a reminder that behind the convenience sits a business that grew explosively fast, is now being squeezed by the very phone technology it was built to compensate for, and is having to figure out what comes next while millions of those little battery packs keep quietly changing hands every single day.
