Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every mobile phone, laptop, and tablet seem to come with their own charger. If you are 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 that is not the original manufacturer’s charger which came with the device?
Types of Chargers
In this article, we will concentrate 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 using a slightly different head or charging cable, these are the most common.
Laptop chargers are rather specific to the device they come with. However, there may be some generic chargers that boast the ability to be interchanged between laptops. This always requires changing of the charger”head” and might 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 if 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 control the Lightning Connector.
The Plugs Must Be The Same
For a charger for use on a different device, it’s essential that the plug of the charger (the”head”) fit securely into the charging port of the device. 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 securely is just one part of this equation.
Determined by the power brick of the charger you will get a label 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 bottom of the charger, in which it would meet up with 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 manufacturer’s website.
Voltage is how much power the charger will draw in the apparatus, or how much is being”pushed” to the device by the charger. A phone will usually pull up to approximately 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 quantity of volts will never change, but the amount of amps that the device pulls may change based on how hard the device is working. The number that you locate on the battery that came with your device will be the max amount of amps which may 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 which can’t support the amp necessity, it may burn out the power supply and kill the device.
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 (so long as the voltage is equivalent ). *Website Note: if you have an older device, it might not work with USB ports that use the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices may have their voltage recorded with a plus/minus on it like that: 5v +- 5%. If this is true, you can use a charger rated at 4.75 to 5.25v because that rating is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts OR 5v plus 5% of 5v = 5.25 volts. So 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 thing to note is all chargers supply a higher voltage than the batteries they charge. That’s pretty much how they operate. There has to be a voltage differential to produce the necessary current flow in the proper way to charge the battery. If 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 they often don’t support the power requirements of the apparatus, or are not built to maintain a steady flow securely. Overall, it’s best to stick with the charger made 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, tablet, or other apparatus. Be sure you follow exactly what we said and you should be ready to go!
