Mojoe Travel Coffee Cup Brews Fresh Hot Coffee On the Go

If you’ve ever tried making coffee while traveling—whether commuting, camping, or road-tripping—you know the struggle: most solutions require pre-boiled water, bulky equipment, or an outlet. Even dedicated travel tumblers and thermoses often fall short when it comes to delivering a truly fresh, hot cup of coffee you can brew yourself, anytime, anyplace.

Mojoe is a portable coffee cup that uses a built-in 14.5Wh lithium-ion battery to brew 251ml of fresh, hot coffee in around 10 minutes at 93°C, without needing pre-heated water or an external power source. One battery makes one cup and recharges in roughly 30 minutes. A full travel kit includes three batteries.

How Mojoe Makes Coffee Without a Kettle or Plug

Mojoe uses a patented brewing method it calls VacDrip—essentially a combination of vacuum and drip brewing all in one self-contained cup. Here’s how it works, step by step:

• Add water to the central chamber inside the cup.
• Pour freshly ground coffee into the side filter basket.
• Press and hold the power button for 3 seconds to start the 30-second heating phase.
• Once the internal temperature reaches 93°C, the device uses an internal tube system to draw hot water up and drip it through the coffee grounds.
• The brewed coffee then collects in the surrounding inner reservoir.
• Total brew time is approximately 10 minutes.

What’s Inside the Mojoe Cup

The cup is designed with both function and usability in mind. Key features include:

• A high-density 14.5Wh lithium-ion battery housed in the base (one battery per brew, 3 included in a travel set).
• An LED indicator light to show when brewing is active.
• A heat-insulating silicone handle for safe handling during use.
• A sealed lid and spout for easy sipping and transport.
• A power button encased in ABS plastic, requiring a 3-second press to prevent accidental activation.

With a total brew output of just 251ml (about 8.5oz), Mojoe is explicitly designed for individual use—perfect for travel-sized coffee needs, whether you’re commuting or hiking.

Battery Life, Charging & Accessories

Each Mojoe battery provides enough power for a single brew and takes roughly 30 minutes to recharge. The base model travel kit includes three batteries, so you can brew up to three cups before needing to recharge.

Additional accessories available include:

• A car charging adapter (+$10)
• Replacement batteries ($59 each)
• Optional coffee, sugar, and creamer sachets (not required—you can use your own)

The standard Mojoe travel kit (brewer + 3 batteries) is available on Kickstarter for $69. Adding the car adapter is optional for an extra $10. Batteries are sold separately.

Frequently Asked Questions

How hot does Mojoe brew coffee?

Mojoe brews coffee at 93°C (approximately 200°F), which is within the ideal range for balanced extraction of coffee flavor compounds without excessive bitterness.

How long does it take to brew coffee with Mojoe?

The full brewing cycle takes around 10 minutes from the moment the water begins heating. This includes the 30-second heat-up time and approximately 9 minutes of actual drip brewing through the coffee grounds.

How many cups can you make with one battery?

Each 14.5Wh battery in Mojoe is designed to brew one 251ml cup of coffee. The starter travel set comes with three batteries, allowing for three back-to-back brews before recharging.

How long does it take to recharge a Mojoe battery?

Each battery takes approximately 30 minutes to fully recharge. There is also an optional car charger accessory available for on-the-go charging.

Is the coffee freshly brewed or just heated?

Mojoe brews fresh coffee on demand using ground coffee and water. It doesn’t simply heat pre-brewed or instant coffee—the unit performs an actual drip extraction with hot water passing through fresh grounds.

What grind size should I use for Mojoe?

The article does not specify an exact grind size, but since it uses a drip-style vacuum brew method similar to pour-over or AeroPress, a medium-fine grind comparable to what you'd use for pour-over is recommended.
