Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, laptop, and tablet seem to come with their own charger. If you’re like me, you have probably compiled a number of chargers over the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet that is not the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this guide, we will focus on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors. Although some devices have chargers with a slightly different head or charging cable, these are the most frequent.
Laptop chargers are fairly specific to the device they include. However, there can be some generic chargers which boast the capability to be interchanged between notebooks. This always requires changing of this charger”head” and might not be the optimal charging amperage or voltage for your device.
Micro USBs are designed to be interchangeable, and are standard in many smartphones, Android devices, and tablets. Micro USB chargers typically have the exact same voltage, but may draw different amps. I will explain this further later and how to know if the charger is safe to use (depending on its listed amps and voltage).
For older devices using a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
The Plugs Must Be The Same
For a charger to be used on another device, it’s essential that the plug of the charger (the”head”) fit securely into the charging port of the unit. Micro USBs are the same across the board so far as charging heads, whilst laptop chargers are usually specific to both make and model. However, the plug fitting securely is just 1 part of this equation.
Determined by the power brick of the charger you’ll get a tag with the charger’s voltage (V) and amperage (A). For other types of chargers, like a smartphone charger, this information is usually located at the base of the charger, where it would meet the wall. For the device you are trying to control, the voltage and amperage required will be seen on the battery that came with the device or on the company’s website.
Voltage is how much power the charger will draw in the device, or how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to approximately 5V, though a laptop can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how fast power is”pulled” to the apparatus, or how much power is used by the device. The amount of volts will never change, but the quantity of amps that the system pulls may change depending on how hard the device is working. The number that you find on the battery that came with your device are the max amount of amps that may be pulled by the device. The number found on the charger is how many amps can be pulled simultaneously. To be able to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a device is paired with a charger that cannot support the amp necessity, it can burn out the power supply and kill the apparatus.
So for those who have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (so long as the voltage is equivalent ). *Site Note: if you have an older device, it may not work with USB ports that employ the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices might have their voltage listed with a plus/minus on it like this: 5v +- 5%. If this is true, you can use a charger rated at 4.75 to 5.25v because that rating is telling you is that the device can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5% of 5v = 5.25 volts. So this means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equal to or higher than the device’s listed amperage).
An interesting thing to note is all chargers supply a higher voltage than the batteries that they charge. That’s pretty much how they operate. There needs to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. If you look at your car, it’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The issue with knockoffs, particularly cheap knockoffs, is they often don’t support the power requirements of the device, or are not built to maintain a steady flow securely. Overall, it’s best to stick with the charger designed for the device you’re using.
Now You Know How To Safely & Effectively Swap Chargers
I hope this article was able to help you. Now you know how to safely and effectively use a charger that did not come with your smart phone, notebook, camera, tabletcomputer, or other apparatus. Be certain you follow what we said and you should be good to go!
