Can You Use Any Charger With Any Mobile Phone, Laptop, 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 computer that isn’t the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this article, we will concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers using 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 the charger”head” and might not be the optimal charging amperage or voltage to your device.
Micro USBs are 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 whether the charger is safe to use (depending on its recorded amps and voltage).
For older devices using a 30-pin charge interface, a connector can be used to control the Lightning Connector.
For a charger for use on a different device, it’s important that the plug of the charger (the”head”) fit snugly to the charging port of the unit. 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 just 1 part of the equation.
How Voltage and Amperage Matter
Determined by the power brick of the charger you will find 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 are attempting to charge, 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 in the device, or how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to around 5V, though a laptop can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how quickly power is”pulled” to the device, or how much electricity is used by the device. The quantity of volts will never change, but the quantity of amps that the device 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 maximum amount of amps which may be pulled from the device. The number found on the charger is how many amps can be pulled simultaneously. 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 which can’t 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, 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 may not work with USB interfaces that use the newest 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 rating is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts OR 5v plus 5 percent of 5v = 5.25 volts.
An interesting point to note is chargers provide 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 way to charge the battery. If you look at your vehicle, 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, especially cheap knockoffs, is that they frequently don’t support the power needs of the apparatus, or are not built to maintain a steady flow safely. This can result in 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 Understand How to Safely & Effectively Swap Chargers
I hope this article was able to help you. Now you know how to safely and efficiently use a charger that did not come with your smart phone, notebook, camera, tabletcomputer, or other apparatus. Make certain you follow what we said and you should be ready to go!
