Can You Use Any Charger With Any Cell Phone, Laptop, Camera, or Tablet?
Every mobile phone, laptop, and tablet appear to come with their own charger. If you’re like me, you’ve probably compiled a number of chargers through 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?
Kinds 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. While some devices have chargers using a slightly different head or charging cable, these are the most frequent.
Laptop chargers are rather specific to the device they come with. However, there can be some generic chargers which boast the capability to be interchanged between notebooks. This always requires changing of the charger”head” and may not be the best charging amperage or voltage for 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 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 using a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
For a charger to be used on a different 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 so far as charging heads, while notebook chargers are usually specific to both make and model. However, the plug fitting securely is only one 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 other types of chargers, like a smartphone charger, this information is usually located at the bottom of the charger, where it would meet up with the wall. For the device you are trying 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 into the apparatus, or how much is being”pushed” to the device by the charger. A phone will usually pull up to around 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” into the apparatus, or how much power is used by the device. The quantity of volts will never change, but the amount of amps that the device pulls may change based on how hard the unit 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. To be able to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a device is paired with a charger that cannot 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 equivalent ). *Site 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 the case, you can 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 plus 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 greater than the device’s listed amperage).
An interesting point to note is chargers supply a higher voltage than the batteries they charge. That is 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. When you look at your vehicle, 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, especially cheap knockoffs, is they often don’t support the power needs of the apparatus, or are not built to maintain a steady flow safely. Overall, it’s better to stay 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 effectively use a charger that did not include your smart phone, laptop, camera, tablet, or other apparatus. Make certain to follow exactly what we said and you should be ready to go!
