FAQs
- Does this unit have an AC (Wall) outlet? The 300D is a DC-optimized station designed for maximum efficiency with modern electronics (Laptops, Phones, Starlink). It does not feature a traditional 3-prong AC outlet, which allows it to be 64% smaller than units that do.
- Can I charge 5 devices at once? Yes, as long as the total power draw does not exceed 300W.
- Is it safe to leave in a car? The 300D is engineered for high-thermal stability (up to 113°F). However, for long-term battery health, we recommend storing it in a cool, dry place when not in use.
- What happens if the built-in cable breaks? The strap is made of high-durability woven material designed for thousands of bends. The unit also features additional USB-C ports, so you are never without a charging option.
- Can I use it for home backup? It is excellent for keeping routers, phones, and tablets powered during a blackout, but it is not intended for large appliances like refrigerators.
