Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every cell phone, notebook, and tablet appear 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 is not the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this article, we’ll 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 common.
Laptop chargers are fairly unique to the device they come with. However, there may be some generic chargers that boast the capability to be interchanged between notebooks. This always requires changing of this charger”head” and might 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 devices, 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 (based on its listed amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to control the Lightning Connector.
For a charger to be used on another device, it’s important that the plug of the charger (the”head”) fit snugly to the charging port of the device. Micro USBs are the same across the board as far as charging heads, whilst notebook chargers are often specific to both make and model. However, the plug fitting securely is only one part of the equation.
Determined by the power brick of the charger you will get a label with the charger’s voltage (V) and amperage (A). For laptop chargers, this charging brick is often halfway down the charger and appears 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, where it would meet 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 company’s website.
Voltage is how much power the charger will draw into the apparatus, or just how much is being”pushed” to the device by the charger. A phone will usually pull up to approximately 5V, though a notebook can pull up to 25V. A charger must equal the voltage needed 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 will never change, but the quantity of amps that the system 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 can be pulled from the device. The amount found on the charger is how many amps can be pulled simultaneously. If a device is paired with a charger that cannot support the amp necessity, it may 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 faster charging (so long as the voltage is equal). *Website 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 Isn’t 5v…
Some devices may have their voltage recorded using a plus/minus on it like this: 5v +- 5%. If this is true, you can use a charger rated at 4.75 to 5.25v because that score is telling you is that the device can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5 percent of 5v = 5.25 volts. So this means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equal to or greater than the device’s listed amperage).
An interesting thing to note is chargers supply a higher voltage than the batteries that they charge. That’s pretty much how they operate. There needs to be a voltage differential to produce the necessary current flow in the correct way to charge the battery. When you look at your car, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The problem with knockoffs, particularly cheap knockoffs, is they often don’t support the energy needs of the device, or are not built to keep a steady flow safely. Overall, it’s best to stay 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 assist you. Now you know how to safely and efficiently use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other device. Make certain to follow what we said and you should be ready to go!
