Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you are like me, you have probably compiled a number of 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’ll concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors. While 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 come with. However, there can be some generic chargers that boast the capability to be interchanged between notebooks. This always requires changing of the charger”head” and may not be the optimal charging amperage or voltage to your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android devices, and tablets. Micro USB chargers typically have the exact same voltage, but may draw different amps. I’ll explain this further later and how to know if the charger is safe to use (based on its recorded amps and voltage).
Apple Lightning Connectors are standard on all new Apple devices, such as 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
For a charger for use on a different device, it’s essential 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 firmly is only one part of this equation.
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 bottom of the charger, in which it would meet the wall. For the device you are trying to charge, the voltage and amperage required will be seen 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” into the apparatus by the charger. A phone will usually pull up to around 5V, while a notebook can pull up to 25V. A charger must equal the voltage required by the device. This is important: drawing too high a voltage could short out the device and possibly even begin a fire, while too low a voltage will fail to charge the battery.
Amperage is how fast power is”pulled” to the device, or how much electricity is used by the device. The amount of volts won’t ever change, but the quantity of amps that the system 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 maximum amount of amps that may be pulled by the device. The amount found on the charger is how many amps can be pulled simultaneously. 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 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 quicker charging (as long as the voltage is equivalent ). *Website Note: if you have an older device, it may not work with USB interfaces that use the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices may have their voltage recorded using a plus/minus on it like this: 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 apparatus can take 5v minus 5% 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 (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 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 proper way to charge the battery. If you look at your car, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The problem with knockoffs, especially cheap knockoffs, is they frequently don’t support the energy needs of the apparatus, or aren’t built to maintain a steady flow securely. This can cause damage to the device but can also pose a safety/fire hazard. 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 include your smart phone, notebook, camera, tabletcomputer, or other apparatus. Be sure you follow what we said and you should be ready to go!
