Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every mobile phone, laptop, and tablet seem to come with their own charger. If you are 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, laptop, camera, or tablet computer that isn’t the original manufacturer’s charger which came with the device?
Types of Chargers
In this guide, we’ll focus on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors. Although some devices have chargers using a slightly different head or charging cable, these are the most common.
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 might not be the best charging amperage or voltage to your device.
Micro USBs are designed to be interchangeable, and are standard in most 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 if the charger is safe to use (depending on its recorded 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 port, a connector can be used to control the Lightning Connector.
In order 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 laptop chargers are often specific to both make and model. However, the plug fitting firmly is only 1 part of this equation.
Somewhere on the power brick of the charger you’ll get a tag with the charger’s voltage (V) and amperage (A). For other types of chargers, like a smartphone charger, this information is usually found at the base 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 device, or how much is being”pushed” to the device by the charger. A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how quickly power is”pulled” to the apparatus, or how much electricity is used by the device. The quantity of volts won’t ever change, but the quantity of amps that the system pulls may change based on how hard the device is working. The number that you locate on the battery that came with your device are the max amount of amps that may be pulled from the device. If a unit is paired with a charger which can’t support the amp requirement, it can burn out the power source and kill the device.
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 quicker charging (as long as the voltage is equivalent ). *Website Note: if you have an older device, it may not work with USB ports that use the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices may have their voltage listed using 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 rating is telling you is that the device can take 5v minus 5% of 5v = 4.75 volts OR 5v plus 5 percent 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 operate. There has to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery. When you look at your car, it has a 12V battery, but typical 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 power needs of the apparatus, or are not built to keep a steady flow safely. Overall, it’s best 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 effectively use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other device. Be sure to follow exactly what we said and you should be ready to go!
