Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you’re like me, you’ve 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 computer that isn’t the original manufacturer’s charger which came with the device?
Types of Chargers
In this article, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablet computers, and cameras), and Apple Lightning Connectors. While some devices have chargers using a slightly different head or charging cable, these are the most common.
Laptop chargers are fairly unique to the device they come with. However, there may 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 best charging amperage or voltage to 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 various amps. I’ll explain this further later and how to know whether the charger is safe to use (depending on its recorded amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices using a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.
For a charger to be used on another device, it’s essential 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 so far as charging heads, while laptop chargers are usually specific to both make and model. However, the plug fitting firmly is only 1 part of this equation.
Determined by the power brick of the charger you will get a label 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 the wall. For the device you are trying to control, the voltage and amperage required will be found on the battery that came with the device or on the company’s website.
Voltage is how much power the charger will draw into the device, or how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to approximately 5V, though a notebook can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how fast power is”pulled” to the device, or how much electricity is used by the device. The amount of volts will never change, but the amount of amps that the system pulls may change based on how hard the device is working. The number that you locate on the battery that came with your device will be the maximum amount of amps that may be pulled by the device. The number found on the charger is how many amps can be pulled at once. If a device is paired with a charger that cannot support the amp requirement, it can 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). *Website Note: if you have an older device, it might not work with USB interfaces that employ the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices may have their voltage listed using a plus/minus on it like that: 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% of 5v = 4.75 volts OR 5v and 5% of 5v = 5.25 volts.
An interesting thing to note is chargers supply a higher voltage than the batteries they charge. That’s pretty much how they operate. There has 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 has 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 that they often don’t support the energy requirements of the device, or are not built to maintain a steady flow safely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stick with the charger made 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 sure to follow what we said and you should be ready to go!
