Is it right to use any charger to charge your smart phone?

You have bought iPhone, iPad, Nexus, Galaxy and a couple of tablets as well. Over the time, you have just stocked up a lot of USB chargers. Will you use the iPhone charger to charge iPad or plug the charger of smart phones of brand for another? Is that right to do so? Have you ever asked yourself such question, ‘Can I use any of the charger for different devices?’

In the past when the mobile devices have not been so diversified, the chargers were still vastly different. We may need to have a check of the output voltage of the charger so that it can just matched the output of the devices we used. The wrong charger may lead to the damage to the charger and the digital gadget as well.

For solving the difference of phone chargers, manufacturers then settled on a standard for USB charging. Almost all of the smart phones or other devices come with USB charger that can be interchangeably used. That just allows us to use any of the USB chargers included with the phone or tablet with any other phone or tablet made after 2007.

If you think all of the chargers are now created equally, you would still need to know more. We all know we need to pick the right charger with the right amperage. Actually, we can use chargers of higher amperage to get the phone charged up in less time than it would if we charge it via USB or we use the charger that came with the phone.

For example, we need to charge an iPad mini. The iPad mini charger delivers 10 watts (5.1 volts at 2100 mA). We can use a lightning connector plugged into a computer via USB, which delivers 2.5 watts of power (5 volts at 500mA) or an iPhone charger connected to a wall socket 5 Watts (5 volts at 1000 mA) to charge the iPad. But the charging time can be longer than if we use the iPad charger. Conversely, we can charge our iPhone very fast if we use the iPad charger.

It is really the amperage that decides how fast a charger will deliver power to our devices. For faster charging, choose a wall charger or car charger that can supply 2100 mA of current at 5 volts.

Still some questions here:

Is it right to use a USB port to charge without a plug in charger? Yes, we can plug our device into any USB port and the device will charge just fine.

Is it right to use a third-party charger with my phone? Yes and just be careful not to buy anything too cheap. Get those well known brand names which perform better and are much safer to use.

Tips for Right Electricity for Electrical Devices We Bring During Trip?

What will you bring with you when you are on a trip, say, an international one? Will you take the things that need electricity? Usually, we need an adapter plug, a voltage converter or transformer. Here we would like to share some tips for you to power up with confidence during trip.

The electrical devices or digital peripherals we use need electricity of different voltages. Those heating devices or device using mechanical motors are dual-voltage, including hair dryer, electric shaver, water heater while those devices using chips or electronic motors are multiple-voltage, including laptop, tablet, e-reader, smart phones, camera, battery chargers. Whatever types the devices are, they need an adapter plug to work in 220V foreign outlets.

There are some electrical devices which are a bit different. They are single voltage ones and require extra voltage converter or a transformer. There is a need to learn about how to read the power supply label of the devices which show whether a voltage converter or transformer is necessary.

Usually, the input of the single voltage device is AC120Vac 60Hz 200W, dual-voltage one AC120/240V 50-60Hz 1300W and multiple-voltage one AC100 - 240V 50-60Hz 14W. Devices with voltage range between 100 and 120V are thought to be single voltage one, for they will not accommodate a 220V power supply.

We need to bring with us an adapter plug to adapt it to 220-volt power supply when we travel to other countries, especially if the devices we take are not single voltage ones and also when the single voltage device is different from the power supply at our destination. Bring with you a voltage converter or transformer.

Now most converters can work as both converter for high watt electrical gadgets and transformer for low watt electric gadgets. Low watts would range up to 25W or 50W, typical for small personal electronics. Electrical heating units may need a “high” setting because they consume 1000W to 2000W.

If you are going on trip to Italy with single voltage electric toothbrush, bring with you an adapter plug for Europe and a converter to reduce the 230V power supply into the 120V power supply. For proper operation of the devices, remember to convert the voltage.

Since now we have more and more mobile devices that are charged via USB cable, we need to take the correct cable for the devices. For better organization and more space, remember to take only one USB wall charger with more USB ports plus a right adapter plug. If not, bring with you the relevant charger for each of the electronic gadgets.
