Sterilizing products are household superheroes these days. And since they’re used so frequently, it’s always a good idea to keep a replacement power bank on hand. The Nursery & Toy Sterilizer utilizes the chemical-free cleaning power of UVC lights – the same ones used by hospitals to disinfect operating rooms – to eliminate up to 99% of bacteria and viruses in the nursery and beyond (baby toys, phones, keys, and more!). Munchkin teamed up with 59S, an innovator in the field of UV LED technology, to develop this germ-killing nursery essential. The 59S Replacement Power Bank is intended only for use with the Nursery & Toy Sterilizer or the 59S Mini Sterilizer as an external battery pack. A USB wall adapter (not included) is required for proper recharging. Please refer to the included owner manual for detailed instructions. Time to power up the clean!
