USB Chargers

A USB (Universal Serial Bus) charger generates the 5 Volt DC power required to charge a USB device. To operate, a charger plugs into an AC outlet. A USB cable connects the charger to the USB device via a Type A socket. USB chargers vary in the amount of electrical amps they handle. USB chargers from CyberPower Systems charge iPods, PDAs, phones, cameras and other personal electronics.

Our USB chargers have various features, depending upon the model. Significant features of this product line include vehicle ports, 2.1-Amp Quick Charge Technology, energy-efficient design elements, and LED indicators. Quick Charge Technology provides fast charging power for tablets, smartphones, and similar devices. USB chargers, cables, and hubs are among the many power accessories available from CyberPower for computer and consumer electronics. Other power accessories include mobile batteries and power inverters.

Lithium Ion Batteries and Quality Performance

Lithium-ion provides quick, efficient performance for rechargeable batteries. Common in notebooks, mobile phones, and other devices, rechargeable lithium-ion batteries have a high power density. Lightweight and convenient, these batteries function well upon frequent, shallow discharges before having to be recharged.

Although lithium-ion batteries can be recharged many times, they may eventually require replacement. Spent batteries should always be recycled or disposed separately from household waste.
