Portable Battery Pack Market

The global portable battery pack market size was USD 16.80 Billion in 2025 and is expected to register a revenue CAGR of 6.5% during the forecast period. Market revenue growth continues to be supported by rising smartphone and tablet penetration and consumer demand for reliable charging while travelling, but the category's growth trajectory over the forecast period is now shaped as much by safety and regulatory response as by consumer electronics upgrade cycles. The International Civil Aviation Organization's new power bank specifications, approved by all 36 ICAO Council member states and effective from March 27, 2026, limit international air passengers to two power banks in the cabin and prohibit charging them during flight, the first coordinated international standard on portable battery limits in aviation, applying across all 193 ICAO member countries. Smartphone and tablet charging, laptop and multi-device charging, outdoor and travel or emergency backup, and drone and camera equipment power are the applications through which portable battery pack demand is expressed. These are some of the key factors driving revenue growth of the market.

Anker Innovations, Belkin International, Xiaomi, Baseus Technology, and RAVPower are among the commercial suppliers that constitute the portable battery pack market, spanning standard smartphone-capacity power banks, high-wattage USB-PD multi-device chargers, and laptop-class fast-charging units. For instance, in January 2025, Anker Technology launched its GaNPrime 27,650 mAh power bank featuring 140W USB-C PD output, the company's highest wattage portable charger at the time, targeting laptop and multi-device power users globally. Anker held market leadership with more than an 11% global share in 2025, while Belkin became one of the first companies to achieve Qi2 25W wireless charging certification the same year, extending magnetic charging capability into its power bank lineup.

However, the same lithium-ion chemistry that makes portable battery packs useful is now the source of the category's most serious commercial risk. The U.S. Consumer Product Safety Commission and Anker Innovations recalled approximately 1,158,000 PowerCore 10000 power banks in June 2025 and a further approximately 481,000 units across five additional models in September 2025, together citing more than 50 reported fire, explosion, and burn incidents, and the Federal Aviation Administration logged a record 97 lithium battery smoke, fire, or extreme heat incidents on U.S. flights in 2025, with power banks accounting for nearly 40% of all such incidents. These factors substantially limit portable battery pack market growth over the forecast period.

Based on capacity, the global portable battery pack market is segmented into below 10,000 mAh, 10,000 to 20,000 mAh, 20,000 to 30,000 mAh, and above 30,000 mAh laptop-class units. The 10,000 to 20,000 mAh segment commands the largest revenue share because it represents the balance point most consumers accept between a full day of smartphone charging and a unit light enough for daily carry, a trade-off that industry guidance consistently identifies as the practical sweet spot between power and portability.

The above 30,000 mAh laptop-class segment is expected to register a rapid revenue growth rate in the global portable battery pack market over the forecast period. Rising adoption of USB-C Power Delivery charging across laptops, tablets, and gaming handhelds is extending portable battery pack demand into higher-capacity, higher-wattage units capable of charging a laptop rather than only a phone, a category exemplified by Anker's 140W GaNPrime 27,650 mAh unit and comparable high-wattage entries from Belkin and Baseus.
