Baby’s Brew portable bottle warmer that was a lifesaver for travel and on the go! One click of power button shows you what percentage of battery is left and if you hold down for a couple seconds, you can choose between various temperatures for warming bottles. Several brands, including Spectra, no adapter is needed- for other brands you can order adapter (see chart in listing pics). Comes with charging cord (company does not provide charging block- we used phone charger block or car charging USB port when needing to charge). Good working condition.
