Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every mobile phone, notebook, 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, notebook, camera, or tablet that is not the original manufacturer’s charger that came with the device?
Types of Chargers
In this guide, we will concentrate 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 unique to the device they include. However, there can be some generic chargers which boast the capability to be interchanged between laptops. This always requires changing of this charger”head” and may not be the optimal charging amperage or voltage to your device.
Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android devices, and tablets. Micro USB chargers typically have the exact same voltage, but may draw various amps. I’ll explain this further later and how to know if the charger is safe to use (based on its listed amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, such as iPads and iPods. For older devices using a 30-pin charge port, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
For a charger to be used on another device, it’s important that the plug of the charger (the”head”) fit securely into the charging port of the device. Micro USBs are the same across the board as far as charging heads, while laptop chargers are often specific to both make and model. However, the plug fitting securely is only 1 part of this equation.
How Voltage and Amperage Matter
Somewhere on the power brick of the charger you will 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 bottom of the charger, in which it would meet up with the wall. For the device you’re trying to charge, the voltage and amperage required will be found on the battery that came with the device or on the manufacturer’s website.
Voltage is how much power the charger will draw into the device, or just how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to approximately 5V, while a notebook can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how quickly power is”pulled” into 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 based on how hard the unit is working. The number that you locate on the battery that came with your device will be the maximum amount of amps that can be pulled from the device. The amount found on the charger is how many amps can be pulled at once. In order to swap chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a unit is paired with a charger that cannot support the amp necessity, it can burn out the power supply and kill the apparatus.
So if you 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 equal). *Website Note: if you have an older device, it may not work with USB interfaces that employ the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices might have their voltage listed with a plus/minus on it like this: 5v +- 5%. If this is true, you may use a charger rated at 4.75 to 5.25v because that score is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts. So this means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equivalent to or greater than the device’s listed amperage).
An interesting thing to note is 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 generate the necessary current flow in the correct way to charge the battery. When you look at your vehicle, it has a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.
The issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the power requirements of the apparatus, or aren’t built to keep a steady flow safely. Overall, it’s better to stay with the charger made for the device you’re using.
Now You Understand How to Safely & Effectively Swap Chargers
I hope this article was able to assist 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 device. Be sure to follow what we said and you should be ready to go!
