How Does Multi-Port Charging Improve Convenience for Travelers?
With four ports (2x USB-C, 2x USB-A), users can charge a laptop, phone, smartwatch, and power bank at once. The compact, foldable design fits easily into bags, eliminating the need for multiple adapters. Universal voltage (100-240V) ensures compatibility worldwide, making it ideal for international travel.
For travelers juggling devices during layovers or hotel stays, the 120W charger simplifies power management. Imagine charging a MacBook Air, iPhone 16, Galaxy Watch, and portable battery simultaneously while preparing for a flight—all through a single wall outlet. The foldable prongs prevent snagging in luggage, and its 3.5-ounce weight is lighter than carrying four separate chargers. Business travelers appreciate reducing cable clutter during conferences, while backpackers benefit from its rugged construction in varied climates. Airlines’ strict carry-on limits make consolidated charging essential, and the universal voltage eliminates the need for bulky converters when hopping between countries with different electrical standards.

Why Is GaN Technology Critical for High-Efficiency Chargers?
GaN semiconductors handle higher voltages and temperatures than traditional silicon, enabling smaller, lighter chargers with greater power output. This technology reduces energy waste by up to 25%, lowers heat generation, and extends the charger’s lifespan.
How Does the Daly Smart BMS Enhance Battery Management Systems?
Gallium nitride’s molecular structure allows electrons to move 100x faster than silicon, minimizing resistance and heat buildup. This efficiency leap lets the 120W charger maintain a palm-sized footprint while delivering enough power for a gaming laptop and three phones simultaneously. Unlike silicon-based chargers that lose 15-20% energy as heat, GaN models operate at 94% efficiency, cutting electricity costs and environmental impact. The material’s thermal stability also enables smarter power distribution—when charging a heat-sensitive device like wireless earbuds, the charger prioritizes cooler 5W streams while still pumping 45W to a tablet. Manufacturers can now pack 3x more power into half the space compared to 2018-era chargers, a critical advancement as devices demand faster energy replenishment.
