Can You Use Any Charger With Any Cell Phone, Laptop, Camera, or Tablet?
Every cell phone, notebook, and tablet appear to come with their own charger. If you are like me, you’ve probably compiled quite a few chargers over 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 that came with the device?
Kinds of Chargers
In this article, we’ll focus on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors. Although some devices have chargers using a slightly different head or charging cable, these are the most frequent.
Laptop chargers are fairly unique to the device they include. 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 might not be the optimal charging amperage or voltage for your device.
Micro USBs are theoretically 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 listed 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 charge with the Lightning Connector.
The Plugs Must Be The Same
For a charger to be used 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, whilst laptop chargers are often specific to both make and model. However, the plug fitting securely is only 1 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 base of the charger, in which it would meet the wall. For the device you are attempting 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 apparatus, or just 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 required by the device.
Amperage is how quickly power is”pulled” to the device, or how much power is used by the device. The quantity of volts will never change, but the quantity 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 are the max amount of amps which can 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 necessity, it may burn out the power source and kill the device.
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 (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 newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices may have their voltage recorded using a plus/minus on it like this: 5v +- 5%. If this is true, you can 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% of 5v = 4.75 volts OR 5v and 5% of 5v = 5.25 volts.
An interesting thing to note is chargers provide a higher voltage than the batteries they charge. That is pretty much how they work. There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. If you look at your vehicle, it’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.
Stay Away From Cheap Knockoff Chargers
The problem with knockoffs, especially cheap knockoffs, is that they often don’t support the energy requirements of the apparatus, or are not built to keep a steady flow securely. Overall, it’s better to stay 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 help you. Now you know how to safely and effectively use a charger that did not come with your smart phone, notebook, camera, tablet, or other apparatus. Make sure to follow what we said and you should be good to go!
