what is a power adapter used for
The article stated that an adapter with a current too high wont cause damage to the cord or device. The tractor pulls the boat effortlessly to wherever you want to go, and most of its power is never used. This was a really helpful article! https://www.sweetwater.com/insync/power-conditioner-voltage-regulator-ups-differences-explained/. Adapter plug looks like a stereo headphone jack and I dont know which part is negative/positive. I realized I actually do have a ups for my computer. On the adapter in question which is called for 1.0 amps input, the plug on the cord going into AC wall says 10amp 120V and on this particular AC adapter cord, its printed on the female end and NOT on the AC male plug end. In an attempt to answer my previous question but instead only to confuse the issue further, I noticed that although the AC cord connectors on several adapters consists of two figure eight female connectors. For my shaving Mashien To check the polarity, look for a + or sign next to the voltage. Using a higher current charger (than the laptop is rated for) will not cause damage to the laptop; as stated earlier. Its not whether the position of the + or is on the left or right that determines the polarity but what sign is attached to the solid circle. PLUGED IT IN AND ALL LIGHTS CAME ON BUT DIDNTRUN THE UNIT. Please reach out at your convenience: jayaallen * gmail.com. Can you help? It is model F4U041 and the coding is something like this: My question is should I continue to use this adapter for my device or i should go to market and look for a new adapter with specs like original one. No wonder when it Chinese but they could still make an effort as for safety purpose and so we dont buy too big amps that are more expensive, for nothing. Current: DC 300mA. What Im confused about is the input amps. A heater, kettle, hairdryer etc. Place the desired socket to the device's male square drive. The other important term to know is polarity. A good magnifying glass is a necessity for me! well I always paid attention to the voltage however I never knew about the polarity. I ended up flunking drum lessons, but for different reasons (lack of talent). Again I would say it would be fine however, if it did need 2.53amps then the Lenovo 2.25amps adapter would get hot and possible that your LG wont get what it needs. Great article. But with insufficient amps, your device may not work at all, or it it does, it will be hard on the power supply, which may overheat and/or fail like the bicyclist trying to tow a boat. And other guys were saying that theres a tolerance range of 2V on all systems; that you can power a Sega Genesis model 2 with a 12V 1A DC without harming the console and that they have been doing that for years! I am asking because on other forums, I learnt (I didnt know) that Super Nintendos and Sega Genesis models 1 and 2 have internal voltage-current regulators which convert all power to 5V, despite the incoming power; that they could handle voltages from 3V up to 15V adaptors! 11.1 10.5 V, 1.0 A Power. I got a portable DVD player from Goodwill online and it didnt include an adaptor so I guess Ill have to buy one. Lets calculate the power of each output : Other common names include wall wart, power brick, wall charger, and power adapter. That was certainly great and very interesting and brilliantly informative, thank you so much. For example if you bought a power supply from Europe that says INPUT: 240V ~1.5A 50hz then it will not work in america or japan or several other countries. Thanks for confirming this! Jack, I appreciate this article and I feel fairly confident I can go ahead and buy this power adapter I found on Amazon, but still, Id like your opinion if I may. Power adapters come in different shapes and sizes, depending on the type of device they are designed for. Just saw this. So I wonder if because I was using a different output voltage that it could be the reason why it wasnt working? I cant seem to find a power supply that goes from 12v outlet to 12v light string. Hey, I plugged a AC 5.5v 2.5A power adapter into a DC 5V charged device, and now its not working, did I do something bad to it? Though the ampere of the adapter is different in different adapters, the range is usually from 0.05A to 3A. Most NETGEAR products use a power adapter (also known as a power supply or AC/DC adapter) that connects the device to a wall outlet. I ended up getting an used replacement from an independent computer repair shop for $20. Some manufacturers put a lot of information on the label. Too much power generates excess heat, which is the bane of sensitive electronics. If your appliance says input: DC 12v/1A, get an adapter that says Output: 12v/1A DC. Making a positive polarity device having the + on the left. POWER ADAPTER OUTPUT :AC 17X2V0.84A An i am still confused with the AC DC FLOW . A movie is like for 2 to 3 hours Max and it works without any problems . 220v is within the range of your device (110-240) so you should have no problem there. Is there any difference if the polarized a circle or diamond. They only had a 4.5v 700 mA charger and he tried plugging it in but it didnt workIm afraid its fried because we cant turn it on anymore. If the manufacturer gave you a 70 watt power supply with your device, you can safely assume that device shouldnt need more power than that. Hello, i was hoping to find a replacement of my Jbl on stage III power supply adapter and i dont know which is which. It should work fine if the Universal adaptor has the correct connectors/pins that match your phone. For the best charging experience, you should use a power adapter or display that provides at least the minimum wattage of the power adapter included with your MacBook Air, MacBook Pro, or MacBook.Learn how to check the power of a connected power adapter or display. V = 8.7 volts, To calculate the value of parallel resistors: Yeah. Stepon Voof. I paid about $80.00 for this thing about 7 years ago and as far as I know, they are no longer being made so I would prefer not to fry it if possible. It operates as an external battery for your computer so that the computer's size does not need to be so large. Perhaps ignore my above comment as I cant delete it and may not be accurate or not explain well. My Yamaha portable keyboard and its power cord were separated during the cleanup. To be clear, the booster units themselves have never blown out, just the power supply units. If its stated 5V, you are not in trouble , because you can use the USB cable to charge your phone by the powerbanks port. I will look into it further. R = V/I Ive seen references to EE type using a multimeter/voltmeter (which I dont have) to check polarity. Power adapters are a bit like canned food. No, the laptop gets 19v, but then reduces the voltage to output to the battery. But what if you accidentally (or purposefully) use the wrong adapter? I turned it off, it made a little different noise the second time and then it didnt work and I smelled smoke. I know that I have to observe the proper polarity, but I cant seem to find a transformer that is provide with just bare wires. The device will only draw as much current (Amps) as it needs at the time. Output: 3-4.5-6-7.5-9-12V The power adapter I am about to buy says, 7.5V 2A for 400mA 500mA 800mA 1000mA DC Adapter Power Supply 5.5mm2.1mm/2.5mm. Thank you again. This was a good explaination and I always had a doubt with these confusing things written on adapters and other devices. I purchased two used RCA 25425RE1-C business phones, but one didnt come with an adapter. The second worst-case scenario is that you fry the gadget you are trying to power up. First of all like to appreciate for such nice and informative article. I know it takes an AD-5 adapter. 19V is too much power and recommend you dont use it. Apple 20W USB-C power adapter. Imagine you want to tow a speedboat. Reread the article and try to follow the examples, check other websites as well if you really want to understand this it just takes time and maybe even somebody in person to show you if you happen to know somebody that is good with this stuff in your neighborhood or your family. Lucky there wasnt a full on fire and I was home to catch it before it got out of control. laying around and Im hoping that one with Just set it to 10V and ensure you have the Polarity set correctly. I have a Belkin USB hub with a port for a charger but the information on the hub has not been described here yet. The original power supply is I have questionwhat if adapter provides an output both different i mean voltage and current??? It will work for a few weeks, then the power supply will die. If your laptop adapter is 19V 2.37 amps (=45watts) and the replacement adapter is 19V 2.1 amps (= 40 watts) is it still safe to use the replacement adapter? Generally, a power adapter that provides a 5V DC current and supports a USB cable is considered a USB power adapter. But if I put an adapter with 24VDC output into a device that requires 5VDC, I can kiss the device and my $120 goodbye. Im willing to bet that any given household has a dozen or more different types of cell phone chargers, AC/DC adapters, power bricks, power cables, and charger plugs. Went back to the store and a very knowledgeable young man discovered that it took at least a 2.0amp charger to charge the unit. I have a box of over 50 power adapters and bricks of all kinds, yet I still have to go searching for the right one regularly for battery chargers, LED lights etc. Once she knows if the Voltage matches then she can buy a power adapter with a higher Wattage without worrying about damaging the device (but not a lower Wattage). Im surprised that it ruined it. I bought my first one from an AT&T authorized dealer. The standard volts to charge your battery is 5V, (It depends on the manufacturer that make your phone). It was a fancy flashlight that you use to work on cars or really light up the night in an emergency, the kind with 5 different modes and all that. Nothing wrong.The adapter will be cooler when working thats good. Current: adapter >=device, I am using adapter 15 V 0.5 Am- 7.5 W Wall adapters that give you a USB port for charging arent nearly as tricky. But 20 makes for simpler math.) = 10.5W An AC adapter or AC/DC adapter is a type of external power supply, often enclosed in a case similar to an AC plug. I use a white paint marker (available at Walmart, Menards etc.) About Apple USB power adapters - Apple Support The voltage on the adapter was lower than on the output TV. Whats making me question myself is that 2A which is not on my radio. CHECK INSIDE THE APPLIANCE THERE MAY BE A FUSE WHICH BLEW. (yes I know these are pretty cheap and I could just buy another hub, but Im tired of throwing things away!!!) Im trying to figure out the diagram of the polarity symbols. Spec on the controller out of prob China makes no sense: i.e. I am trying to determine the polarity on my 1st Gen Kindle. This applies to most if not all of such design including the headphones and them huge speakers. The universal power supply has circuitry to adjust the voltage to the needed level and the maximum current would also change such that the product is 90W. The amperage (current) of the plug can be higher than that of the device but not lower. Like a garden hose.the wider it is the more water can pass through it. -DC Output: 19.5V 11.8A 230W So. The following will cause harm to your power cord or adapter: The following might not cause damage, but the device will not work properly: Higher current adapter than device rating. The Zagg ifrogz 7800 power supply calls for a 1.0amp input. I was leery of their claims that it would be okay, since they want to sell me a new laptop after I fry it. The device will only draw what it requires from the power pack. P = V*I -Jeff. Now if I can find a plug that will work in the EU that has the same output would it then work without me burning down my house? Current, as the term implies, refers to the flow rate. A power supply for electronic devices. If you have a universal adapter, ensure it has the proper current rating and choose the correct voltage and polarity. the input polarity is + c the adapter output is c + but the fitting fit perfect but Im not going to plug it in until i get a response. If so can i get a plug that can be 12 volts DC 5 amp im thinking if im at 100ma which is smaller then max 5 amp i should be ok, I cant see how to set up a new comment. You cant inflate a balloon unless you put higher pressure into it. If the adapter says Input: 100 240 V (standard USA AC input voltage) and 50/60 Hz, then its the standard cycle rate of the power. You should not worry. I felt heat suddenly on my device, so I removed it from the power source. I have a photo but dont know how to attach it. Im a little confused on a different term of VA. Lol) a replacement (9V 0.2A DC). In this analogy, the voltage would be the water pressure. Ill assume the TV is 12v and requires 4amps or less based on your noted original adaptor? The new adapter works the 20 Watt bulb in the tree but does not turn the color wheel. The short version: Voltage (V) should always be the same for both adapter and device. First of all, what a great post! What is the volt requirement of the device? Not enough power. Your article gives me hope that, if I spend a few bucks at Radio Shack, I can revive my device by buying the right adapter. For instance, a device than needs 12v at 100ma, would would work fine on an adapter that provided 12v at up to 500ma, Do you think its a good idea to use a voltage meter to make sure that what the numbers say on the power supply are the same as what is really coming out of it, This thread / Post is a keeper for answering the very confusing Power adapter replacement dillema every one faces. The numbers you are reading are for the battery itself and only concern replacing the battery. Adapters for battery-powered equipment may be described as chargers or rechargers (see also battery charger ). Here I place something different. If you grab an incompatible power adapter, your best case scenario is that it works, albeit not the way the manufacturer intended. That said and considering the info perfectly explained on this post, I want to know if this new adaptor will harm my console? Polarity: The tip and sleeve (inside and outside of connector) must be the correct polarity. But the number of watts alone wont tell you if the adapter is right for your device. I Even tried a different brand power adapter. what if the diagram is a complete circle in the middle? P.S. Backblaze is the solution I use and recommend. i have 3 power cords that say (10/16 A 250 V), is there any problem to use any of them in any device? How USB Charging Works, or How to Avoid Blowing Up Your Phone The tip is positive the usually plastic gap separates it from the next segment which is negative. 1.5v x 8 = 12V, BUT on the side where the power adapter plugs in, it says: DC IN 9.5V, Why the difference?
