AUDIOTEK PI900 12V 420W Power Inverter

The AUDIOTEK PI900 is a compact DC-to-AC power inverter designed to bring household-style AC power to a 12V vehicle battery system. It provides a practical way to run compatible small electronics and charge USB-powered devices while traveling, working remotely, or using a vehicle-based power setup. Its rated continuous output is 420W, so connected equipment should remain within that rated load.

This inverter is suited to drivers, campers, boat users, and mobile work setups that need AC outlets away from a wall receptacle. Dual AC outlets allow more than one compatible device to be connected, while the USB charging output supports common 5V USB-powered gear. For loads above 150W, the included battery clips are intended for direct battery connection rather than a typical vehicle accessory outlet.

The PI900 converts 12V DC input power to 110-120V AC output for portable use in cars, trucks, boats, and other 12V battery applications. It is rated at 420W continuous power, with 840W maximum power and 900W peak power stated by the manufacturer. These ratings make power planning important: add the rated wattage of connected AC devices and keep the total below 420W for continuous operation.

Built-in serviceable protection hardware supports dependable everyday use. The inverter uses two replaceable 30A fuses and a cooling fan, and it is specified with over-voltage, overload, over-current, under-voltage, overheat, and short-circuit protection. The compact enclosure measures 8.75 by 4.5 by 2.5 inches for easier placement in a vehicle or portable power kit.

For a basic mobile-power upgrade, the PI900 can be used with a 12V battery system and compatible electronics that need AC power or USB charging. It includes both a cigarette-lighter plug and black/red battery clips, giving users two connection methods based on the load and vehicle setup. Use the direct battery clips for higher-demand applications as directed, and ensure the positive and negative terminals are securely tightened before use.

Key Features

• 420W Continuous Output: Supports compatible AC loads within its rated continuous-power limit.
• 900W Peak Rating: Provides short-duration peak capacity for startup demand.
• Dual AC Outlets: Lets you connect two compatible household-style AC devices.
• 5V/2.1A USB Output: Charges compatible USB-powered phones, tablets, and accessories.
• Replaceable 30A Fuses: Two serviceable fuses simplify maintenance after a protection event.
• Vehicle And Battery Connections: Includes a cigarette-lighter plug and direct battery clips.

Design & Installation

The PI900 uses a compact black enclosure with a built-in cooling fan and replaceable fuse arrangement. Its 8.75 x 4.5 x 2.5-inch footprint is intended for portable use where space is limited. The integrated protection functions are designed to respond to over-voltage, overload, over-current, under-voltage, overheating, and short-circuit conditions.

Connect the inverter to a 12V DC battery source using the included cigarette-lighter plug for lower-power use or the included black/red battery clips for direct battery connection. The manufacturer advises using the battery clips when the rated input of connected AC equipment exceeds 150W, since many vehicle 12V accessory outlets are rated and fused for 150W. Keep total connected AC load below 420W, secure the battery terminals tightly, and place the inverter away from prolonged direct sunlight and heat-sensitive materials.
