STARSEEKER S58 / S58 Pro Portable Travel Coffee Maker

Professional 58mm espresso. No power outlet. No compromise.

The STARSEEKER S58 is a portable electric espresso machine built around a commercial-standard 58mm bottomless portafilter — the same basket size used in professional café machines. A 150W rare-earth thick-film heating system, 20-bar high-pressure pump, detachable dual-mode handle, and a 13,500mAh USB-C rechargeable battery combine to deliver authentic, full-bodied espresso wherever you are. Available in S58 and S58 Pro.

Key Features:

• Commercial 58mm Bottomless Portafilter | 18–20g Capacity: The S58 uses a full commercial-standard 58mm bottomless portafilter — a larger extraction surface than most portable machines, producing richer body, improved flavour balance, and full compatibility with standard 58mm espresso accessories. Use your existing baskets, your preferred dose, your preferred grind.
• 150W Rare-Earth Thick-Film Heating | 25% Faster: An advanced rare-earth thick-film heating element delivers 25% faster heat-up than conventional portable espresso makers — 50ml of water reaches 92°C in approximately 140 seconds, 80ml in approximately 220 seconds. Less waiting, more brewing.
• 20-Bar High-Pressure Pump | Rich Crema: The integrated 20-bar pump extracts coffee evenly and efficiently — producing rich crema, full-bodied flavour, and balanced espresso comparable to a traditional semi-automatic machine. Professional extraction pressure in a portable form.
• Detachable Dual-Mode Handle | Portable & Tabletop: The handle detaches and reattaches to switch seamlessly between portable mode for travel and tabletop mode for home use — recreating the locking and brewing workflow of a professional espresso machine for a more authentic extraction experience.
• Dual Brewing Modes | Cold Water & Hot Water: Cold Water Mode automatically heats water to 92°C before extraction — ideal for outdoor use with no pre-heating required. Hot Water Mode brews instantly using pre-heated water for maximum speed and efficiency. One machine, every scenario.
• 13,500mAh Battery | USB-C Charging: High-capacity rechargeable battery delivers 6–8 full espresso shots from room-temperature water, or up to 800 cups when using pre-heated water. Recharges via USB-C from any power bank, laptop, wall charger, or vehicle — no proprietary charger required.
• 3-Mode One-Button Control: Single press for espresso extraction. Double press for pre-infusion + extraction. Triple press for full cycle: heating + pre-infusion + extraction. Intuitive enough for beginners, precise enough for experienced baristas.
