Can You Use Any Charger With Any Cell Phone, Laptop, Camera, or Tablet?
Every mobile phone, laptop, and tablet appear 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 that came with the device?
Kinds of Chargers
In this guide, 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. 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 may be some generic chargers which boast the ability to be interchanged between laptops. This always requires changing of this charger”head” and might not be the best charging amperage or voltage to your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in many smartphones, Android devices, and tablets. Micro USB chargers typically have the exact same voltage, but may draw various amps. I will 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, such as iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
In order for a charger to be used on a different device, it’s essential that the plug of the charger (the”head”) fit securely into 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 one part of this equation.
Determined by the power brick of the charger you’ll 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, where it would meet up with 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 in the device, or just how much is being”pushed” into the apparatus 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 required by the device.
Amperage is how fast power is”pulled” into the apparatus, or how much power is used by the device. The quantity 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 find on the battery that came with your device will be the maximum amount of amps that can be pulled by the device. The number found on the charger is how many amps can be pulled simultaneously. To be able to exchange 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 source and kill the apparatus.
So if you 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 equivalent ). *Site Note: if you have an older device, it might not work with USB interfaces that employ the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices might have their voltage listed using 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 apparatus can take 5v minus 5 percent of 5v = 4.75 volts OR 5v plus 5 percent of 5v = 5.25 volts.
An interesting thing to note is all 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’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.
The problem with knockoffs, particularly cheap knockoffs, is they frequently don’t support the energy requirements of the apparatus, or are not 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 better 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 help you. Now you know how to safely and effectively use a charger that did not come with your smart phone, laptop, camera, tablet, or other apparatus. Make sure you follow exactly what we said and you should be ready to go!
