Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet seem to come with their own charger. If you’re like me, you’ve probably compiled quite a few chargers through the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet computer that isn’t the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this guide, we’ll concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors. Although some devices have chargers using a slightly different head or charging cable, these are the most common.
Laptop chargers are rather specific to the device they include. However, there may be some generic chargers that boast the ability to be interchanged between notebooks. This always requires changing of this charger”head” and might not be the best charging amperage or voltage for your device.
Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android apparatus, 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 recorded amps and voltage).
For older devices with a 30-pin charge port, a connector can be used to control the Lightning Connector.
In order for a charger to be used on another device, it’s important that the plug of the charger (the”head”) fit snugly to the charging port of the device. Micro USBs are the same across the board as far as charging heads, whilst notebook chargers are often specific to both make and model. However, the plug fitting firmly is just one part of this equation.
How Voltage and Amperage Matter
Determined by the power brick of the charger you will get a tag with the charger’s voltage (V) and amperage (A). For notebook chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually located at the bottom of the charger, where it would meet the wall. For the device you’re attempting to control, 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 in the apparatus, or how much is being”pushed” into the device by the charger. A phone will usually pull up to around 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” to the apparatus, or how much electricity is used by the device. The quantity 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 locate on the battery that came with your device will be the max amount of amps that can be pulled from the device. To be able to swap 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 requirement, it may burn out the power source and kill the apparatus.
So for those who have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (so long as the voltage is equal). *Site Note: if you have an older device, it might not work with USB ports that use 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 the case, you may 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 percent of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts.
An interesting thing to note is chargers provide a higher voltage than the batteries 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 direction to charge the battery. If you look at your vehicle, it’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy requirements of the device, or aren’t built to keep a steady flow securely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stick with the charger designed for the device you are using.
Now You Know 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 include your smart phone, notebook, camera, tabletcomputer, or other device. Make certain to follow exactly what we said and you should be good to go!
