Can You Use Any Charger With Any Cell Phone, Laptop, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you’re 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 computer that isn’t the original manufacturer’s charger that 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. Although some devices have chargers using a slightly different head or charging cable, these are the most frequent.
Laptop chargers are rather unique to the device they include. However, there may be some generic chargers which boast the ability 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 designed to be interchangeable, and are standard in many smartphones, Android devices, and tablets. Micro USB chargers typically have the exact same voltage, but may draw different amps. I will explain this further later and how to know if the charger is safe to use (depending on its recorded amps and voltage).
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 for use on another device, it’s important that the plug of the charger (the”head”) fit snugly to 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 firmly is only 1 part of this equation.
Determined by the power brick of the charger you will get a tag with the charger’s voltage (V) and amperage (A). For laptop chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds — a brick. 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 trying to control, the voltage and amperage required will be seen on the battery that came with the device or on the company’s website.
Voltage is how much power the charger will draw into the apparatus, or how much is being”pushed” into the apparatus by the charger. A phone will usually pull up to around 5V, though a laptop 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 potentially even begin a fire, while too low a voltage will fail to charge the battery.
Amperage is how quickly power is”pulled” into the apparatus, 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 depending 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 number found on the charger is how many amps can be pulled at once. If a device is paired with a charger that cannot 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, tablet, or camera) you can plug into a high-amperage USB port and enjoy faster 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 Is Not 5v…
Some devices may have their voltage recorded using a plus/minus on it like this: 5v +- 5%. If this is the case, 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 percent of 5v = 5.25 volts.
An interesting thing to note is chargers provide a higher voltage than the batteries that they charge. That is pretty much how they work. There has to be a voltage differential to generate the necessary current flow in the correct 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 needs of the device, or aren’t built to keep a steady flow safely. Overall, it’s better 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 effectively use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other device. Be certain you follow what we said and you should be good to go!
