An alternate current (AC) adapter converts the AC from your wall outlet into direct current (DC), which is the type of power your laptop uses. Most ASUS® laptop batteries have the model number and voltage printed on a label, so you can find out easily which replacement battery your device requires. If your battery has no information written on it, you can use software to determine which replacement is the right one for you. When choosing a new AC adapter for your laptop, make sure that the replacement matches not only the power connector of your device, but its amperage and voltage as well. This information is usually printed on a label on the laptop case or next to the power port. The amperage of the ASUS AC adapter of your choice must match or exceed the one your laptop requires.
The universal laptop power adapters from ASUS can output different voltages to meet the requirements of different devices. A power adapter recognizes the differences because of a switching mechanism in the tip. Most universal AC adapters have multiple tips to work with a variety of laptop models. Some models have 3.0mm, 4.0mm, 4.5mm and 5.5mm tips to work with most 90W laptops from the brand.
ASUS also makes USB Type-C™ adapters for laptops. Most of these can automatically detect the voltage required. The USB-C port on ASUS laptops provides bi-directional power, and tit can receive up to 100W, charging the battery faster than before. It can also transmit audio and video signals for added versatility. USB-C is backward compatible with USB 2.0 and 3.0. Since USB-C is a universal connection standard, you can use a network adapter to charge other compatible tech gadgets as well, like smartphones and tablets. When buying one of those AC adapters, make sure that the USB-C port on your laptop is suitable for charging, and that the connectors on the charging cables are correct.
GreenASUS certified battery chargers are RoHS compliant, and they adhere to strict quality standards. They're environmentally-friendly, thanks to lead and halogen-free manufacturing processes, and a green supply chain management system. They're easy to recycle, disassemble and reuse. The ASUS laptop AC adapters are power-efficient, and comply with hazardous substances guidelines.
Most ASUS laptop batteries are lithium-ion, so they offer a low self-discharge rate. They can sit unused for weeks without losing their charge. Lithium-ion batteries lose around 5% of charge in a month. They have a high current output to charge your device fast. These batteries support up to 150WH per kg. Most ASUS models are compact and lightweight, so you'll be able to carry an extra battery around with little effort. Most ASUS lithium-ion batteries have six or eight cells for extra power and longer life. Both types can last for several hours between charges.
