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, notebook, camera, or tablet that is not the original manufacturer’s charger that came with the device?
Types of Chargers
In this article, we will concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors. While some devices have chargers with a slightly different head or charging cable, these are the most frequent.
Laptop chargers are rather unique to the device they come with. However, there can be some generic chargers that boast the ability to be interchanged between laptops. This always requires changing of this charger”head” and might not be the optimal charging amperage or voltage for 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 same voltage, but may draw different amps. I’ll explain this further later and how to know whether the charger is safe to use (based on its listed amps and voltage).
For older devices using 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 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 as far as charging heads, while laptop chargers are often specific to both make and model. However, the plug fitting securely is only one part of this equation.
Somewhere on 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” to the apparatus by the charger. A phone will usually pull up to approximately 5V, though a laptop can pull up to 25V. A charger must equal the voltage required by the device. This is important: drawing too high of a voltage could short out the device and potentially even begin a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” to the device, or how much power is used by the device. The quantity of volts won’t ever 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 max amount of amps that may be pulled by the device. The amount 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 recorded 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 device.
So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy faster charging (so long as the voltage is equivalent ). *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 Is Not 5v…
Some devices may have their voltage listed 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 score is telling you is that the apparatus can take 5v minus 5 percent of 5v = 4.75 volts OR 5v plus 5% of 5v = 5.25 volts. This means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equal to or higher than the device’s listed amperage).
An interesting point to note is chargers supply a higher voltage than the batteries they charge. That’s pretty much how they operate. There needs to be a voltage differential to produce the necessary current flow in the proper 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 that they frequently don’t support the power needs of the device, or are not built to maintain 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 stay 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 include your smart phone, laptop, camera, tabletcomputer, or other device. Be certain to follow exactly what we said and you should be good to go!
