Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, laptop, and tablet seem to come with their own charger. If you’re like me, you have probably compiled quite a few 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 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 phones, tablets, 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 fairly specific to the device they include. However, there can be some generic chargers that boast the capability to be interchanged between notebooks. This always requires changing of this charger”head” and may not be the best charging amperage or voltage to your device.
Micro USBs are theoretically 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 listed amps and voltage).
For older devices using a 30-pin charge port, 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 unit. 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 only one part of the equation.
Somewhere on the power brick of the charger you will find a label with the charger’s voltage (V) and amperage (A). For laptop chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. For other types of chargers, like a smartphone charger, this information is usually found 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 seen 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 apparatus, or how much is being”pushed” into 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 quickly power is”pulled” to the apparatus, or how much electricity is used by the device. The amount of volts won’t ever change, but the amount of amps that the system pulls may change depending 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 that may be pulled by the device. The amount found on the charger is how many amps can be pulled simultaneously. If a unit is paired with a charger which can’t support the amp necessity, it can burn out the power supply 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 faster charging (so long as the voltage is equal). *Website Note: if you have an older device, it may 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 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 score is telling you is that the apparatus can take 5v minus 5 percent of 5v = 4.75 volts OR 5v and 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 work. There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. If you look at your car, it’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.
The issue with knockoffs, especially cheap knockoffs, is that they often don’t support the power requirements of the apparatus, or aren’t 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 best 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 apparatus. Be sure you follow exactly what we said and you should be good to go!
