Can You Use Any Charger With Any Cell Phone, Laptop, Camera, or Tablet?
Every mobile phone, notebook, and tablet appear to come with their own charger. If you’re like me, you’ve 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 which came with the device?
Types of Chargers
In this guide, we will focus on three types of chargers: laptop 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 specific to the device they include. However, there can be some generic chargers that boast the ability to be interchanged between laptops. This always requires changing of the charger”head” and may not be the optimal charging amperage or voltage to your device.
Micro USBs are 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 different 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).
For older devices with a 30-pin charge port, a connector can be used to control the Lightning Connector.
The Plugs Must Be The Same
In order for a charger for use on another 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, whilst 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’ll find a tag 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 base of the charger, where it would meet up with the wall. For the device you’re attempting to control, the voltage and amperage required will be found on the battery that came with the device or on the manufacturer’s website.
Voltage is how much power the charger will draw in the device, or how much is being”pushed” into the device by the charger. A phone will usually pull up to around 5V, though a laptop 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 amount of volts will never change, but the amount 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 are the maximum amount of amps which can be pulled by the device. The number found on the charger is how many amps can be pulled simultaneously. If a device is paired with a charger which can’t support the amp necessity, it may burn out the power source and kill the apparatus.
So for those who 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 ). *Site Note: if you have an older device, it may not work with USB ports that employ the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices may have their voltage listed with a plus/minus on it like this: 5v +- 5%. If this is the case, 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 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 (as long as the amperage of the charger is equivalent to or greater than the device’s listed amperage).
An interesting point to note is all chargers supply a higher voltage than the batteries they charge. That is 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. If you look at your vehicle, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The issue with knockoffs, particularly cheap knockoffs, is that they often don’t support the power needs of the apparatus, or are not built to maintain a steady flow safely. Overall, it’s best to stick with the charger made for the device you’re 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, notebook, camera, tablet, or other device. Make certain to follow exactly what we said and you should be good to go!
