Portable Charger laws in California

In California, the ownership and use of portable chargers, also known as power banks, are generally permitted without specific state-level legislative restrictions. The primary regulatory considerations for portable chargers in California, particularly for travelers, stem from airline regulations rather than state law. These regulations, often enforced by the Transportation Security Administration (TSA) in coordination with federal aviation authorities, focus on the lithium battery content within these devices due to fire safety concerns. While there are no California statutes criminalizing the possession or use of portable chargers for personal use, individuals must adhere to specific transportation guidelines. The most significant regulation dictates that lithium batteries in portable chargers, when carried on an aircraft, cannot exceed 100 watt-hours (Wh). This limit is designed to mitigate the risk of thermal runaway incidents during flight. Exceeding this capacity may result in the device being prohibited from carry-on baggage, and packing them in checked luggage is strictly forbidden due to the increased risk and the inability of cabin crew to monitor potential issues. Practical considerations for residents and travelers in California concerning portable chargers primarily involve compliance with airline policies. It is advisable to check the specific battery capacity of any portable charger before traveling by air, as most standard power banks fall within the 100Wh limit. Devices exceeding this threshold, which are generally of higher capacity and less common for personal use, may require special approval or be completely banned. Failure to comply with these aviation security directives, while not a state criminal offense, can lead to the confiscation of the device or denial of boarding.
