Yes, a Kensington charger can typically be used with devices from other brands, provided that the charger meets the necessary specifications for voltage and amperage required by the device. Most modern chargers are designed with compatibility in mind, which allows them to work with a range of products. However, it is important to check the specific requirements of your device to ensure that the Kensington charger you plan to use is compatible, particularly if it is a laptop or other higher-powered device. Additionally, using a charger that does not match the required specifications may lead to performance issues or even damaging the device. It is also a good idea to verify that the connector type of the Kensington charger fits your device. For more detailed compatibility information, users may wish to consult the product specifications on the current Kensington website or the documentation that came with both the charger and the device.
