MITSU Power Supply ACE19158 — 19V 1.58A AC adapter for portable devices

MITSU Power Supply ACE19158 is an AC adapter that provides a 19V output at 1.58A for compatible portable electronics. It is intended as a replacement or external power source for devices that accept a 19V/1.58A input and offers a compact form factor suitable for travel, office, or home use. The adapter supplies steady DC power to charge batteries or run devices directly when the original adapter is unavailable.

Advantages

The adapter delivers a regulated 19V output with a 1.58A current rating, ensuring stable power delivery within the adapter's rated limits. Its compact size and standard AC input make it convenient for portable use and for carrying in laptop bags or travel kits. The unit is designed to be a simple plug-and-play replacement for compatible devices, reducing downtime when an original power supply is missing or damaged.

Suitable for

• Portable electronics and laptops that require a 19V DC input and draw up to 1.58A
• Use as a spare or replacement power adapter at home, office, or while travelling
• Situations where a compact, lightweight AC adapter is preferred for everyday charging and operation

When it may not be suitable

This adapter is not appropriate for devices that require voltages other than 19V or currents exceeding 1.58A; using it with mismatched voltage or insufficient current can cause unreliable operation or failure to charge. It may also be unsuitable for devices that need proprietary connectors, communication protocols, or smart charging features that the adapter does not provide.

Key specifications

• Output voltage: 19V DC
• Maximum output current: 1.58A
• Power output: approximately 30W
• Input type: AC mains input (regional plug may vary)
• Form factor: external inline AC adapter — compact and portable

How to use

Confirm that your device accepts a 19V DC input and that its required current does not exceed 1.58A. Connect the adapter to AC mains using the included or suitable regional power cord, then plug the adapter output connector into the device's power jack. Observe the device's charging or power indicators and disconnect the adapter from mains before unplugging from the device. Use the adapter on a stable, ventilated surface and avoid covering it while in operation.

What to consider before purchase

• Verify device compatibility with a 19V DC input and a maximum current draw of 1.58A or less
• Ensure the adapter's output connector matches your device's power jack or that an appropriate adapter tip is available
• Confirm the regional AC plug type or availability of a suitable power cord for your location

Usage recommendations

For reliable operation, match voltage exactly, do not exceed the adapter's current rating, and avoid prolonged operation in high-temperature or poorly ventilated environments. If your device requires smart charging features or firmware-managed power delivery, use the manufacturer-recommended adapter.
