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 are like me, you’ve probably compiled a number of chargers over the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?
Types of Chargers
In this article, we’ll focus 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 with 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 may be some generic chargers which boast the capability to be interchanged between notebooks. This always requires changing of this 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’ll 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.
For a charger for use on a different device, it’s important 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 notebook chargers are usually specific to both make and model. However, the plug fitting securely is only 1 part of this equation.
Somewhere on the power brick of the charger you’ll get a tag with the charger’s voltage (V) and amperage (A). For notebook chargers, this charging brick is often halfway down the charger and appears exactly like it sounds — a brick. 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 the wall. For the device you are attempting to charge, 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 just how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to approximately 5V, while a notebook can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how quickly power is”pulled” into the apparatus, or how much electricity 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 will be the max amount of amps which may be pulled by the device. If a unit is paired with a charger that cannot support the amp requirement, it may burn out the power supply and kill the device.
So for those who 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 may not work with USB ports that employ the newest Battery Charging Specification.
If The Micro USB Charger’s Voltage Isn’t 5v…
Some devices might 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 device can take 5v minus 5% of 5v = 4.75 volts OR 5v and 5 percent 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 chargers provide a higher voltage than the batteries they charge. That is pretty much how they operate. There has to be a voltage differential to generate the necessary current flow in the proper 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 that they frequently don’t support the energy requirements of the device, or are not built to keep a steady flow safely. Overall, it’s better 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 help you. Now you know how to safely and effectively use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other apparatus. Make certain to follow what we said and you should be ready to go!
