Proper usage and maintenance of AC/DC Power Adapters — Desktop & Wall-Mount

We explain the proper and safe usage, as well as maintenance, of AC/DC Power Adapters — Desktop & Wall-Mount. We offer advice on how to use AC/DC Power Adapters — Desktop & Wall-Mount for as long as possible.

How to Extend the Lifespan of AC/DC Power Adapters — Desktop & Wall-Mount

Avoid High Temperature and Humidity Environments

The standard operating temperature range for Unifive's AC/DC Power Adapters — Desktop & Wall-Mount is 0 to 40°C, but due to the characteristics of the internal components, higher temperatures shorten their lifespan.

For example, compared to a product used at 20°C, the lifespan of a product used at 40°C—20°C higher—is reduced to about a quarter.

Even when used indoors with air conditioning, if it's placed in a confined space at the back of a shelf or clustered on a power strip, localized heat may increase the temperature. Placing it under a blanket or cushion may cause it to warm up like a kotatsu, raising the device temperature and reducing its lifespan.

Although humidity itself does not affect lifespan, temperature changes in a high-humidity environment may cause condensation inside the product, damaging internal circuitry. Strictly speaking, this is not a lifespan issue, but a premature failure.

From the perspective of AC/DC Power Adapters — Desktop & Wall-Mount, internal condensation corresponds to the situation previously described in our newsletter, “Do Not Get It Wet!”.

Unplug and Clean the AC Pins About Once Every Six Months

This is also not a lifespan issue, but is related to our past newsletter “About Tracking Prevention…”, and is also featured on the Product Safety Guide page of the Ministry of Economy, Trade and Industry.

There is a risk of fire in some cases, so we recommend regular cleaning of not only AC/DC Power Adapters — Desktop & Wall-Mount but also all electrical product AC plugs.

Unplug AC/DC Power Adapters — Desktop & Wall-Mount for Devices Not in Use

Many modern devices remain in standby mode with current flowing even when switched off.

Unplugging AC/DC Power Adapters — Desktop & Wall-Mount for unused devices not only extends their lifespan but also saves power and prevents tracking—achieving three benefits in one action.

Of course, using power strips with switches provides the same effect, but in that case, regular maintenance such as cleaning the AC pins for tracking prevention is still necessary in addition to switching on/off.

Examples of Improper Use That Shorten the Lifespan of AC/DC Power Adapters — Desktop & Wall-Mount and Proper Installation Practices

Follow the Connection Order of AC/DC Power Adapters — Desktop & Wall-Mount to Avoid Electrostatic Discharge Troubles

Electrostatic discharge (ESD) is invisible, but can cause serious damage to electronic equipment. Static electricity can reach several kV, with enough energy to destroy electronic components. It is one of the main causes of failure in AC/DC Power Adapters — Desktop & Wall-Mount due to damage to internal parts.

To prevent this, always follow the correct connection order:

1. First, connect the DC plug of the AC/DC Power Adapters — Desktop & Wall-Mount to the electronic device.
2. Then, plug the AC/DC Power Adapters — Desktop & Wall-Mount into the wall outlet.

This order is important because connecting the DC plug first allows the adapter to ground, providing a safe path for static electricity. Connecting to the outlet first raises the risk of discharge by allowing static to accumulate.

Proper static measures improve safety and help extend the lifespan of both the AC/DC Power Adapters — Desktop & Wall-Mount and your electronic devices.

Unifive also supports requests for long-life AC/DC Power Adapters — Desktop & Wall-Mount or models that operate over a wide temperature range.
