Charged well and heat water pretty quickly!If you are customers like me who need hot water all day and need to travel around, this one is perfect for you! The only issue is that you cannot expect it to keep the water warm, it is getting cool after ~ 2 hours.This little boiler is great for traveling and taking to work. It make one cup of boiling water, dries fast, cools down easily and easy to store. Fits in any cup holder or pocket of a suitcase. Works very well.This is a great product and I really do like it and I would recommend it to anybody 100%After a long wait after ordering I finally received the water glass.At first it worked, however, only worked for 1-2 minutes. It stopped working.The indicator light is no longer on.I think it should be broken.I'm so disappointed I can only return it to Amazon now.I waited up to 15 days to finally receive the package.But to my disappointment, the cup is broken, it doesn't heat up, and the display doesn't light up when powered on.I think it's a poor quality industrial waste.I can only return itI'm pretty impressed by this water kettle! It's shaped like a thermos, so unlike a traditional water kettle, this does not have a spout. That shape gives it a portability that most water kettles don't have. It's really easy to use and pretty sleek: there is a touch-sensitive spot near the bottom that turns it on and lets you set the desired temperature. Once the temperature is selected, you let it sit for a minute, and it begins to heat up the water, even up to boiling. Then, once it hits the temperature, it will keep it warm, as long as it stays plugged in. It also uses a LOT less power than a standard 110V electric kettle. A typical electric kettle will use something like 1200 watts. This uses 300 watts, which makes it a lot more ideal for camping or other places where power is somewhat limited. But, the lower power did not affect performance, including the amount of time it took to boil. It was as fast as any other electric kettle I've used.There are a few quarks that make it function a bit differently from a standard electric kettle. First, you are supposed to unplug it before pouring (there isn't an obvious reason for this, but the instructions indicate that it should be done to avoid damage). Second, pouring it feels different without a spout. However, neither of those are a downside or at all problematic. Also, don't assume that because it's shaped like a thermos, it will function like a thermos. I unplugged it, and the water was cold within 30 minutes. That's no problem as long as you aren't expecting it to be thermos-like.Also, it should be noted that the water tasted great. Sometimes kettles make the water taste weird because of whatever is lining the interior. This one doesn't have that problem at all.I definitely recommend this as a portable water kettle. It's versatile, super easy to use, and pretty sleek.It’s sleek, there is a nice weight to it. Making it feel expensive and not light and cheap. This kettle is not heavy though. Just the right balance. the hidden socket is a bonus. The Silacone cap is attached so you don’t end up loosing it later down the line. It’s flush to the walls too. The cord is solid, not to short and not to long.There are only 3 parts to the kettle.. lid, shell and plug. After use you can just store the cable plug in the kettle.The indicator light is large enough that my mom can read the numbers without her glasses but not to bulky for design astetics. You touch the words touch switch to activate. Not the indicator screen. There are 3 settings to choose from.The max level of water capacity is 1 1/2 cups of water. It took 5 min to bring to a boil of ice cold water to the high test setting.This is a win for me. I’ve used this for a personal French press, tea, oatmeal. I am excited to find and try many more things for this kettle.This is perfect for travelers, mothers for baby bottle formula or even cleaning bottles on the the go. Dorm rooms , even being a guest in someone’s home. You can make that early morning tea or coffee without even leaving your room.This is a simple, easy and portable way to just make a cup of hot water at a time. I got it to take camping for an easy way to make a cup of hot chocolate but I am also going to keep it at home to take into the office for a quick cup of hot tea.
