Primo Passi USB Portable Smart Bottle Warmer

I like the design and the concept of this product, but it just doesn't work as well as I'd hoped. It takes 20+minutes to heat 4 oz from cold to lukewarm, using up an entire battery pack in the process (one that can usually recharge my phone 2-3 times). When plugged into the car instead of a battery pack I've had it run for 40 minutes and still not great the bottle enough. I'll still use it occasionally, but we've discovered it's much faster and easier to bring a wide-mouth Yeti with hot water to put the bottle in than it is to use this product.

i still can not figure out how from fahrenheit to celsius some time popup celcius itselfno way to fit second dr.brown bottleswhy not adding a small battery pack in side package ?but keep at 113 water with an usb source that's great, my advise is preheat water before use this NO BUTTON TO CONVERT MILK OR FORMULAOR CHANGE CELSIUS TO FAHRENHEIT WEIRD CHANGE ITSELF RANDOMLY ONLY ?

How the heck am I supposed to use it without its PowerBank?You advertised it with the powerbank and I thought it came with it and was disappointed when it didn't have it.Meanwhile I have to order another item to power this thing up

Maybe I just didn’t use it for long enough or it didn’t heat evenly with the contoured bottles we use, but it seemed like it only heated the bottle. The milk/formula was hardly above room temperature.

Perfect for road trips/events after realizing I had to heat up the bottle to the desired temp first then use the pouch to keep it at that temp. May be different for formula I'm not sure as we use breastmilk.

It is great for keeping a bottle warm but not for heating a cold bottle. Most of the heat is on top so the lid feels the warmest when you take it out.

The idea is great; however, it does not warm up the best and the LCD screen is not user friendly. It change to one setting and I have not been able to get it back to what I want it to be. :( Again the concept of this item is great it just needs to be improved on.

I like this bottle heater on the go. It’s takes a long time and a lot of power to heat the bottle, so I always bring 2 external battery to charge this bottle heater.
