Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, 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 isn’t the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this article, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors. While some devices have chargers using a slightly different head or charging cable, these are the most common.
Laptop chargers are rather 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 this charger”head” and may not be the optimal charging amperage or voltage for 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 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 (based on its listed amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices using a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
The Plugs Must Be The Same
In order 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 notebook chargers are often 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 get a tag with the charger’s voltage (V) and amperage (A). For notebook 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 located at the base of the charger, in which it would meet the wall. For the device you’re attempting to control, the voltage and amperage required will be seen on the battery that came with the device or on the manufacturer’s website.
Voltage is how much power the charger will draw into the device, or just how much is being”pushed” to the device by the charger. A phone will usually pull up to around 5V, while a laptop can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how quickly power is”pulled” into the apparatus, or how much electricity is used by the device. The amount of volts will never change, but the amount of amps that the device pulls may change depending on how hard the unit is working. The number that you locate on the battery that came with your device are the maximum amount of amps that may be pulled from the device. If a device 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, 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 might not work with USB ports 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 score is telling you is that the apparatus can take 5v minus 5 percent of 5v = 4.75 volts OR 5v and 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 equivalent to or higher than the device’s listed amperage).
An interesting point to note is chargers provide a higher voltage than the batteries that they charge. That’s pretty much how they work. There needs to be a voltage differential to produce the necessary current flow in the correct way to charge the battery. If you look at your car, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The issue with knockoffs, particularly cheap knockoffs, is that they often don’t support the energy 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 designed for the device you’re 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, laptop, camera, tabletcomputer, or other device. Make sure to follow what we said and you should be ready to go!
