All Opoggi warmth products are designed with a USB-A connection for universal compatibility. While you can use your own powerbank, it’s essential to ensure it meets safety and performance standards. Always check that your powerbank is CE certified, free of defects, and has an output of 5V - 3A for optimal heating. If the output is lower, the product may not reach its full warming potential.
To guarantee safety and the best performance, we strongly recommend using an Opoggi battery. This battery is specifically designed to work perfectly with all Opoggi warmth products, giving you peace of mind and maximum comfort. If you’re unsure about your powerbank’s compatibility, the Opoggi battery is the ideal solution.
