Can You Use Any Charger With Any Mobile 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 quite a few chargers through the years. So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet 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 phones, 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 frequent.
Laptop chargers are fairly specific to the device they come with. However, there may be some generic chargers which 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 to 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 same voltage, but may draw various 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 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 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 unit. Micro USBs are the same across the board as far as charging heads, whilst notebook chargers are often specific to both make and model. However, the plug fitting securely is only one part of this equation.
Determined by the power brick of the charger you’ll find 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 base 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 device, or just 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 won’t ever change, but the quantity of amps that the system 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 max amount of amps which can be pulled by the device. If a device is paired with a charger which can’t support the amp requirement, 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 equal). *Site Note: if you have an older device, it might not work with USB ports that employ the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices might have their voltage listed using a plus/minus on it like that: 5v +- 5%. If this is the case, you may 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 plus 5% of 5v = 5.25 volts. So 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 thing to note is all chargers provide a higher voltage than the batteries they charge. That’s pretty much how they work. There has to be a voltage differential to produce the necessary current flow in the proper way 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.
The issue with knockoffs, particularly cheap knockoffs, is they frequently don’t support the power needs of the device, or aren’t built to keep a steady flow securely. Overall, it’s better to stick with the charger made for the device you are using.
Now You Know 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 include your smart phone, laptop, camera, tablet, or other device. Be certain you follow exactly what we said and you should be good to go!
