What's the difference between AC and HVDC? Follow

AC stands for Alternating Current and is the form in which electric power is delivered to your home and workplace. There are many different waveforms of AC and Omnicharge uses the one called modified sine wave, which approximates the pure sine wave AC from your home wall outlets. Omnicharge's modified sine wave inverter has two main advantages over a pure sine wave inverter:

• A smaller form factor

• Higher efficiency

The trade-off of modified sine wave AC is the possible buzzing sound from the vibration of Omnicharge's transformer and your device's internal circuits.

Don't worry if you are having trouble with the buzzing sound. Omnicharge also features HVDC (High Voltage Direct Current) which can eliminate the buzzing sound. Nowadays most modern power adaptors that come with your laptops, cameras and cell phones are switched-mode power supplies. These power adaptors are designed for AC, but can also be run from DC (HVDC) because the DC would pass through the rectifier inside and remain unchanged. HVDC mode also has two advantages over AC:

• No buzzing sound

• Higher efficiency

IMPORTANT:

• How do I know if my laptop's power adaptor is a switched-mode power supply?

We recommend you consult with your device manufacturer to check first. Chances are good though since almost ALL modern laptops and smartphones use switched-mode power supplies and can work with Omnicharge's 150V HVDC

• What will happen if I use HVDC with a Non-switched-mode power supply?

HVDC can damage a Non-switched-mode power supply's. Please consult with your device manufacturer first if unsure.
