Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet seem to come with their own charger. If you are 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 isn’t the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this article, we’ll 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 come with. However, there can be some generic chargers that boast the ability to be interchanged between notebooks. This always requires changing of this charger”head” and may not be the optimal charging amperage or voltage to your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in many smartphones, Android apparatus, and tablets. Micro USB chargers typically have the same voltage, but may draw various amps. I’ll explain this further later and how to know if 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 control the Lightning Connector.
In order for a charger for use on another device, it’s essential 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 so far as charging heads, whilst notebook chargers are usually specific to both make and model. However, the plug fitting firmly is just 1 part of the equation.
How Voltage and Amperage Matter
Somewhere on the power brick of the charger you will find a label with the charger’s voltage (V) and amperage (A). For other types of chargers, like a smartphone charger, this information is usually found at the bottom of the charger, where it would meet up with the wall. For the device you’re trying 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 into the device, or just how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how fast power is”pulled” to the apparatus, or how much electricity is used by the device. The quantity of volts won’t ever 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 which can be pulled by the device. In order 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 which can’t support the amp necessity, it can burn out the power source 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 faster charging (as long as the voltage is equivalent ). *Website Note: if you have an older device, it might not work with USB ports that employ the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices may have their voltage recorded with 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 apparatus can take 5v minus 5 percent of 5v = 4.75 volts OR 5v plus 5 percent of 5v = 5.25 volts.
An interesting point to note is all chargers provide a higher voltage than the batteries that they charge. That is pretty much how they work. There has to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery. When you look at your vehicle, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy needs of the device, or are not built to keep a steady flow securely. This can result in damage to the device but can also pose a safety/fire hazard. Overall, it’s better 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 efficiently use a charger that did not include your smart phone, laptop, camera, tablet, or other apparatus. Make sure to follow exactly what we said and you should be ready to go!
