Carrying a bunch of chargers for different devices like smartphone, iPads, Laptop and your camera is always a pain in the ass. When all have almost one of the standard ports for charging but why carry a different cable and charging brick for different devices. Hold on, do not consider all chargers with the micro USB port to be the same. There is a lot of parameters you should know to understand how well a charger suits a device. Does it reduce charger speed? Will using an inappropriate charger reduce its life?
Charger for Multiple Devices
Here we will discuss the science of charger and devices and how they can be mixed and matched to cover all your devices with minimal charging equipment to carry. Let us start with knowing the types of connectors, charging standards and basic parameters of charging.
Different Types of Charging Ports
Gone are the days of proprietary charging ports, one charger for multiple devices is common nowadays. Pre-smartphone era, I would say, is when all of the brands had their own proprietary ports and it was not comfortable to carry charger wherever you go. Then came the USB standards which all portable devices adopted soon and some special scenarios where Apple created an own standard for themselves and market space too. Following are the most common charging ports that are found on 99% of the devices currently in the market.
Micro USB port – common among mid-range and budget smartphones, watches and most of the accessories. Smartphones have started to ditch the Micro USB port for a more powerful USB C port.
USB C Port – Advanced version of USB standard. Allows faster-charging capabilities and better data transfer rates than Micro USB.
Lightning Port – this is Apple proprietary port that is found only in Apple iPhones, iPads, and accessories.
All these ports are interchangeable with the help of adapters and converters. Though most of them are not official from the OEMs they are reliable for the most part. You can buy one of them to cross-connect and charge your device with a common charger and cable.
What to Look Out in Your Charger?
As said not all chargers with the same port are the same. The amount of power delivery is entirely a different story. Consider a Bluetooth headset and smartphone, though they share the same Micro USB port the headset has an input rating of not more than 0.5 Ampere whereas the smartphone usually takes in 2 Amp input. Using a low current charger will take forever to charge and using a high current wall adapter can put your device to sleep forever. So look out for the following parameters before choosing the charger.
The output voltage of charging brick: This is set to a standard 5 Amp unless it has fast charging capabilities.
Output Ampere of charging brick: This can take values from 0.5 Amp to 2.1 Amp. Check whether it matches with the input rating of the device to make a wise choice.
The input voltage of charging brick: Input voltage should be anywhere around 110 V or 220 V depending upon the country. You live in and almost all the charger nowadays is rated for both the voltage levels. Input frequency of
Charging brick: That too is very similar to the input voltage. Either 50 or 60 Hz.
Know the power output ratings from the wall socket and check whether it matches with your available charging brick. Then match the input of the device and the output of the charging brick. Also, check if the cable is capable of carrying the required input of the device. By getting to know the basics of chargers, devices and their input/output ratings you can reduce the bulk of chargers you need to carry around . We would recommend carrying a single wall charging brick and different cables to suit your needs as almost every cable attaches to the charging brick using a standard USB port.
