BHPian tbppjpr recently shared this with other enthusiasts: When we go in the high altitude places like Himalayas, we suffer from low oxygen levels. There the most natural source of oxygen is drinking water. But due to high altitude and chilling atmosphere, our drinking water also gets icy chilled and undrinkable, as a result we end up consuming far less water than needed. Have faced this many a times during my Himalayan trips. So I’m looking for:A hygienic, easy-to-clean water bottle that can warm water using USB power, either from a car charging port during drives or from a power bank while hiking.Some safety measures like auto power cutoff, temperature control etc are important while using it in the car.Power efficiency also matters since power bank’s limited capacity has to cover cameras, phones, and other devices as well during long hikes.The bottle should be compatible with the standard cup holder size in cars to fit it securely.Bottle should not be too large and heavy to fit in the cramped space in the hiking bag.Capability of making coffee/tea on the go will be an added advantage.Finally, it should be reasonably priced, many options online seem overpriced.Here’s what BHPian freelancer6202 replied:Finding a usb powered might be hard. heating element requires lots of power which usb might not deliver, hence the expensive price. I would suggest investing in an Anker power station with ac power. you can use normal electric kettles and power up your devices for a really long time.Here’s what BHPian ChasingSpots replied: There are 12v car kettles, if its only water you are after – so simple tea/coffee. Here is one listed. Seems reasonably priced too! Haven’t used it , but on my list for the next trip. Note, when using this, it is better to keep the car running, as it may drain the battery quite a bit. Assuming a ICE car. Of course this won’t work on hikes. In fact on hikes, making your own fire is the easiest one as any power source that capable will add lot of weight. However, it should be done only by trained as there is a risk of starting a forest fire etc. Check out BHPian comments for more insights and information.
