Read on to understand further about ac wall adapter and its importance.

How to Choose the AC Wall Adapter

Very often, smart device users wonder what is AC adapter charger?

AC wall adapter is the powerhouse for your smart devices, tablets, and laptops. It needs some careful consideration before you buy one.

Input and Output Voltage

Check the input voltage and output voltage of the adapter.

The input voltage should match with the public supply voltage rating at your house or office.

Generally, the adapters come with input voltage rating from 100 V – 220 V AC, which is fine with most of the electrical installations in the home /office/airports, etc. Check out the Wikipedia page for all the countries and their input voltage.

DC Voltage

Check the output voltage in DC of the adapter. It should match with the requirement of the devices you propose to charge with this charger.

One important consideration here is checking the polarity of the output socket with that of the device. The electronic devices are polarity sensitive, and hence, this matching is essential.

There can be two possible configurations, as shown in the above figure. The charger and the device should have identical polarity configurations.

Also, check the current and power rating of the adapter or charger. It should be sufficient for the devices to be charged.

All this technical information is mentioned on the label attached to the charger as with the devices too.

It would be helpful here to mention the formula

Wattage = voltage x current, which will help you derive any unknown parameter with the help of the other two.

And finally, look out for the safety protection that the charger offers. The charger should have at least the basic warranty and also the customer support services.

Regular vs. Fast charge adapters

Speed – The fast charge adapters as the name suggest charges your device faster than the regular chargers.

Power = current x voltage. Higher current is delivered by the fast chargers, keeping the voltage constant. This increases the output power, and hence the device charges quickly. 

The fast chargers deliver the current above 2 amps. As against this, the regular charges deliver current up to 1 amp.

Compatibility – The fast charger will work only with those devices that are compatible with quick charge technology. The new age smart devices generally are fine handling the higher current. But the old feature phones may not sustain a higher current rate. However, the regular charger works with all devices.

Since the device is charged quickly, you can use it more as compared to devices charged with regular chargers.

Device Protection – The fast charges come with lots of protection features for the connected devices. Regular chargers are just for basic charging, with no additional features.

Multi Usage – With just one new generation fast charger, you can charge phones, tablets, laptops, and such other smart devices.  But the regular chargers are suitable only for the phones.

Overheating – Because of fast charging, sometimes the connected devices heat up, but protection systems inside the charger prevent damage to the devices. Usually, the regular charger does not heat the phones.

Why it is essential to have good quality AC adapter

Let us see the reasons for have a good AC wall adapter.

Power Supply

Most of the smart electronic devices work on DC, and the supply available in the house or workplace is AC. So, we need an adapter to convert the AC supply to DC supply.

A good adapter will genuinely deliver a DC supply where there are no pulses of AC at all. This pure filtered DC is very healthy for the device because pulsating DC can reduce the life of the device or force it to under perform.

A good quality Adapter ensures proper rectification and filtration of the output power.

Safety

A good quality AC wall adapter will always deliver the right voltage at the output, which keeps the charged device safe.

Heating

A good quality AC adapter will not heat when in use. This feature is very critical because if the adapter heats up, it means that it is underrated for charging and will eventually damage the charged device.

Device Protection

Adequate and appropriate protection systems come inbuilt with a good quality AC wall adapter. It protects the chargeable devices from overheating, short circuits, over current, and overcharging.

Quite often, we plug the phone to the charger and leave it unattended for an extended period of time. If the adapter does not have the protection system, the phone, or any device connected to it, is susceptible to severe damage.

Convenience

It is usual to have several devices, like phones, tablets, or laptops these days, and a good quality charger should be able to charge all of them. It is very inconvenient to carry different chargers for these different devices.

Having known about the importance of the AC wall adapter and why its important, it is time to choose a one.
