Yes. USB-C Power Delivery (PD) is a global standard. While some of our chargers feature designs inspired by specific brands (like the clean square look for Apple or HP), the internal technology is universal. You can safely use an Elcostar charger to power a MacBook, a Dell XPS, a Lenovo ThinkPad, or an ASUS Zenbook, provided the laptop supports USB-C charging.

Absolutely. This is the most common concern, but it’s perfectly safe. Our chargers use Smart Voltage Detection. When you plug it in, a "digital handshake" occurs: the laptop tells the charger exactly how much power it can handle and the charger adjusts its output (5V, 9V, 12V, 15V, or 20V) to match. A 100W charger will only ever "push" the 45W or 65W your device asks for.

The 100W version is "future-proof" and more powerful:

- Faster Charging:It can fast-charge high-end laptops (like the MacBook Pro 16") at their maximum speed.
- Versatility:It has the "overhead" to charge a laptop and still have enough power to fast-charge a smartphone or tablet simultaneously if using a multi-port model or cable splitter.
- Cooler Operation:Since a 100W charger doesn't have to work as hard to provide 65W, it often stays cooler and lasts longer.

Yes. Because of the Smart Voltage Detection, the charger will recognize that your phone only needs 5V or 9V and scale down immediately. This makes the Elcostar laptop charger an excellent all-in-one travel companion. You can charge your laptop and then use the same cable to fast-charge your iPhone, Samsung or iPad.

Cheaper, low-quality chargers often produce "electronic noise" (ripple voltage) that can interfere with your laptop’s sensitive components. Our chargers are engineered to stay under 200 mV, providing a stable, clean stream of power. This prevents the "ghost touches" on trackpads and the high-pitched whining sounds often found in budget replacements.
