Portable USB Feeder Warmer Pouch | 42°C Constant Heating

The item works well, it heats a bottle properly, satisfied and I fully recommend it.

works excellent

In fact, on the red indicator (60), it heats up to about 37 degrees in 30-40 minutes from room temperature. And on green or blue, you can only maintain the temperature of the already prepared food. Heating on them is not efficient in terms of time. Works on a power bank, from a socket. It's better to get a better cord and charger than the original one. To prepare the mixture, after feeding, immediately pour a new portion of water into the bottle and keep it warm until the next feeding. In principle, it will be suitable for a device that can operate on a power bank while traveling. But most importantly, the power bank needs to be quite large. In 30 minutes it heated up to 7% charge.
