Most efficient electric kettle to boil 1 or 2 cups?

Looking for the most efficient water boiling device to run off a solar powered battery setup.
That could also be used at home. Any suggestions?

Seems like the worst solution to a simple problem. Boiling water over fire is so easy. Why complicate things with a battery, solar charger, and electric kettle?

Haha, great points! I do need a kettle for home anyway, and I’ll be getting the solar panels and battery to power other electronics for remote work while camping. This kettle will serve me for camping, traveling in an RV, and at home when I don’t have time to build a fire for tea during work.

Most kettles draw over 1500W. A small canister stove and butane would be your best bet unless you want to avoid fossil fuels. Correction, there are a few 900W models out there.

I have a 500W kettle with stainless steel inside for traveling. It doesn’t require much battery, and I recharge it quickly with solar or vehicle charging. It’s handy and easy to use. Not all kettles take 1500W.

This sounds perfect! Do you have a name and model number to share, or a way to find it in the States?

For comparison, my Jackery 600Wh solar power station outputs a max of 800W. The new 1000Wh model can output 1500W, but it costs $800 just for the power station.

@Wray
Pecron, Bluetti, and OOPS have models that can output over 1500W for under $500. But for you, a backpacking stove with a stainless or aluminum kettle boils water faster and is cheaper.

All kettles will be nearly 100% efficient! All energy goes directly to making heat.

Not true. I have a 900W kettle, but it takes forever to boil 1 liter of water. I still prefer my Jetboil.

Electric kettles consume a lot of power. Boiling over a fire is better. However, I have a 20 oz. portable kettle I use camping and at home.

You won’t boil water well with solar and batteries fit for camping. Too much energy is required. Use a Jetboil for camping and an electric kettle at home. If you have solar on your house, that’s beneficial.

A low-wattage hotel kettle could work. Slow but safe.

Yes! Those are perfect. I forgot about those. Thanks.

Using electricity for heat takes a lot of wattage. A compact stove and gas canister is the best solution away from mains power.

Once, my friends brought an electric hotpot camping. We drained the battery with just one meal!

You could consider this kettle: Kettle Pot – Stoke Voltaics. It will still use a lot of electricity.

From their website: 880ml capacity, rolling boils in 300 seconds, made of 304 stainless steel, compatible with all 500W+ power stations. At $99, it’s a bit pricey but might be perfect.

Thanks!

If you have sun, have you tried repurposing an old satellite dish or an umbrella with a Mylar coating? Someone must have a reasonable idea for non-daylight hours.
