Things to Consider When Buying a Portable Coffee Maker that Heats Water

  1. The type of power that the coffee maker uses. Some portable coffee makers are only compatible with electricity and can not be powered using your car battery. Similarly, some car battery-powered coffee makers do not have a separate adapter for electricity. Therefore, you may want to sift through the available coffee makers to select the right one for you.
  2. Rechargeability. Some portable coffee makers use batteries such that you recharge the coffee maker and brew coffee until the battery runs out of charge.
  3. Size and Weight. A portable coffee maker should be compact and lightweight. Anything above five pounds may be too heavy to carry around, especially when backpacking. It should have a small footprint to fit in tiny spaces
  4. Type of coffee. Choose a portable coffee maker that brews your favorite type of coffee such as drip or espresso-style. A coffee maker that uses both coffee pods and ground coffee gives you more flexibility when brewing coffee.
  5. Brewing time. Portable coffee makers that use car adapters are notorious for longer brewing times. If you have access to electricity, consider using a coffee maker that has a wall adapter.
  6. Cleaning. It should be easy to clean on the go.
