I lost my PS2 Super-Slim power cable, and I want to play the PS2, but I have one for my PS3. Thank you sire for a very comprehensive guide about ac/dc adapter. I am much better informed. Hook them up in parallel and R will be 2 ohms. First of all like to appreciate for such nice and informative article.
First of all, what a great post! Therefore, finding the right AC adapter for your electronics requires selecting a compatible third-party accessory. Thank You, Nico, Your email address will not be published. Hello, I have a 19v dc output charger that only has two out cables, I need to charge it to three output cables.
i was hoping to find a replacement of my Jbl on stage III power supply adapter and i dont know which is which.
It didnt seem to work (no power on light). I turned it in to a note on my phone to remember forever. I bought a 12 volt electro-thermal cooler which came with a 120 volt ac adapter showing output of 13 volts.
I am surprised that there is no markings on it at all showing the power requirements (check next to power input and also on the botto Sidenote, these come with 3 year warranty, so also make note of this to Belkin as they may send you a replacement. @MikeM Is .5v enough to really be concerned if I chose to use the 4.5v setting?
Sidenote: I will stand corrected as I am not an electrician but I wouldnt use it. Required fields are marked *. bkp homedics Thank you so much!! Same deal. Here is the info I have on the adapter and battery: Class 2 power supply Input 120VAC 60Hz 21.6W Output 9VDC 500mA. if yes than how much??
my elliptic gym trainer LED display needs 9 v DC input , 1.5 A current. When learning how to choose an AC adapter, it is also necessary to understand power adapter specifications.
(more or less depends on the device), V should be same (more or less-depends on the device) Output: 6Vdc, 750mA.
Your phone also will receive a 5V voltage and will damage if above that rating. THANK YOU for this article!!!! Re: If no Input voltage, current, or polarity noted. 117 x 48 x 34mm. That would be enough to educate any lay person worried or simply frustrated to know if they are making a mistake, I have looked at universal plugs with adapters but have an issue with them as they are vague on differing polarities. Alan Moore. 4' cable with 2.1mm coax plug, HDP# MTPE051CE-055075. Will I have problems?
The Volts are important and generally the power required by your device. The article mentions, If you multiply the voltage by the current, you get the wattage. It will be fine for your weather station which only requires 600ma.
Its helps but its not a perfect system. Is there a website to look up an adapter that you have no clue what device it is for? Also, under the current too high section above, it explains that its OK if your power supply is rated for MORE current (amps) than the device needs; the device will only draw the current it actually needs.
Great tip!
Is ther any damage can happen to my shaver. good to know! Thats the amount of amps the adapter will put out. But i found that the output of the woofer was like around 90% to my satisfaction than when it was working on the original Creative Adaptor.Besides the Adaptor is getting heated up.
60/50Hz The amperage output will self-adjust controlled by your device.. My device is a negative polarity and need to know which polarity symbol on the adapter matches negative polarity. I am having trouble understanding how to determine the quantity and raitings of Aluminum Clad resistors I would need in order to bring a 1212 1/8 aluminum plate up to a temperature of around 100-120 C. Also how to wire them. Furthermore, on the fuse box, it says on a label on it: INPUT 100 -240V ~ 1.5A, and the PS3 power cable says 250V 2.5A. Read this guide on finding the right charger or power adapter. Current: DC 300mA.
Depends on what type of adaptor and device you are describing here.

If I could get one style of adapter that worked on every computer appliance/device (including external hard drives) then Id be willing to pay a mint for it, and then get multiples of the adapter for backup. It is model F4U041 and the coding is something like this:
On the back of the phone, it says 10V DC, 500 mA, and positive polarity.

(Youve probably also heard about resistance (), but this doesnt usually show up on power adapters.). Remember: the input of the device should be the same as the output of the adapter. The AC/DC adaptor has the following information on it: Input: 120 VAC 60Hz 135 mA. But if I put an adapter with 24VDC output into a device that requires 5VDC, I can kiss the device and my $120 goodbye. Center positive. PHC # SW-9600A. It requires a 4.2v and 600 mA charger. It is great and now I will bring it with me to Europe. More info needed. If the device has a DC input of +12V / 5.4A, get an adapter with a DC output of +12V / 5.4A. The specs of the AC-DC adapter are as follows: Input: 110/220V AC Power adapters numbers are just averages and never exact so I dont recommend it but if its your only option and it works then you have no choice as long as you can live with the risk. On another note, nothing is more irritating than the plugs that are proprietary the old Apple 30 pin ones for example. If I have a cord that is 120v 60hz and 9w can that be used with a device that calls for 120v 60hz and 15w? I am using the 3 volt setting but my equipment is not operating correctly.. What mA should my AC-DC adapter have? Your email address will not be published. Ideally, youll have the same voltage, current, and polarity on your adapter and device. P.S.
Also: seperate to this, ensure the polarity is also correct. Device no longer works does work on a duplicate power brick. The transformer in the adapter regulates the voltage and polarity to ensure that the power received by the electronics are consistent with their specifications. The HP 65W Smart AC Adapter allows you to conserve battery life on your HP Business Notebook.
Ill recommend this page to everybody I know. e001 adaptor intertek If you plug an adapter with all the correct voltage/amperage into something that was designed to have a trickle charge once it is full, you will overcharge the battery and destroy it because adapters dont trickle charge like chargers do.
I always used the if it fits its the right one mentality, guess 6' cord with 3.5mm mini-phone plug, tip negative. In theory, it shouldnt damage the device however good chance the adaptor will suffer.
My external harddrive has ALL of my family photos so Im afraid to even try to see what happens. The charger is designed for this and can be use is globally. Read more about the first steps you should take when deciding on an AC adapter. Alright, I hope this message will help you with your problem. I have a 10000mah powerbank that only has usb cable. http://www.warrencat.com/company/benefits-ups-systems This makes more sense than all the electronic matchmaking.
is that saying that the device internally will adjust the polarity to whatever it needs? Quick question: Am I supposed to match the specs from the power adapter to my laptop battery or the laptop itself? Stepon Voof. Great information!! In some cases, OEM adapters are no longer available from manufacturers.
Even slightly off will it mess up my my devices? Nothing wrong.The adapter will be cooler when working thats good.
Can you help? Institute of Industrial and Systems Engineers
Is the replacement one compatible with the original? Even then it does not matter the input is just an acceptable range.
That it must have come with a faulty adapter? Its for a watch winder (not anything too elaborate or expensive). Unfortunately, it looks like theres only one real seller of the adapters, and I ordered one from ebay, but never received it, so I was wondering if I could make a universal adapter work for the phone, such as the Original Power Powerline 600 mA Universal AC Adapter found on the Walmart website (it says 3-12V DC at up to 600 mA)? Ill assume the TV is 12v and requires 4amps or less based on your noted original adaptor? If it has a battery, it probably wont charge, it might charge if the device is not running. I have a car amplifier. In this analogy, the voltage would be the water pressure. As part of that process, I took all my power supplies and adapters and threw them into a box. Any advice would be appreciated. I had a 100-240V 50/60hz input on my TV my sister gave me, and had been using a power plug that was 12V4A, then all of a sudden, it stopped working. Thank you so much for a really helpful article. On this machine near electric connection point, DC 6V is written.
Battery specs: 6V 4.5A.
Many times struggling to read whats printed on those plugs. I cant seem to find a power supply that goes from 12v outlet to 12v light string. second 6 amp is enough for a LED Christmas Tree. Choice of 3, 4.5, 6, 9 and 12 volts AC or DC. POWER ADAPTER OUTPUT :AC 17X2V0.84A The EU 2 pin plug that I have found, matches the keyboard info and the polarity. I went to Radio Shack and bought an adapter that can be used with multiple tips, along with the correct tip for my device, and all is well again.
Furthermore, USB devices are smart enough to shut things down if something isnt right.
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. Tweaking any of these three variables increases or decreases the amount of electrical power sent to your device. The fuse will die in such case and you cant turn on your device until tou replace the fuse. Go figure.
Most plug is fused at 5A as standard could this damage my adapter? My dog chewed on my SeaGate External Harddrive wire so now Im trying to find a replacement AC Adapter. Great post bro, I kept wondering what if the voltages were the same but the current is lower than the other. 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. P = V*I Thats true?
The only standards that electronics (usually) conform to are in regards to the wire gauge and respective maximum current. Theyve sent me at least 10 replacement adapters. Can I use an adaptor with 9v DC and 1.0 A output? but now after reading your post last night, i think i already have the idea of what kind of adapter i should look at. But that would prevent us from being forced to buy more crap! So, you can see the power of the Samsung Galaxy Note 3 is 10.6W and the powerbank is 5W and 10.5 W. You can choose which port did you want to connect the Samsung Galaxy Note 3 to the powerbank.
Input: 120Vac, 60Hz, 10W.
The DC voltage (VDC) of the power accessory is as important as its AC voltage (VAC). Its AC in DC out, not AC OR DC.
The device will only draw as much current (Amps) as it needs at the time.
This happens if the adapters VDC is lower than the devices input voltage even when their current ratings are the same. This is a weather station that is made of wood that is illuminated with LEDs that actually shine through the wood laminate. I have a photo of the adapter if needed. If I could then it must be negative polarity, otherwise it is positive polarity.
I learned that lesson early, when I plugged in my tiny tiny cassette player into this mammoth brick. I have my Samsung Galaxy S3, on the battery it reads, 3.8 V and 7.9 Wh please someone tell me what my USB is supposed to be.
AC 100 240 V~ (+/- 10 %), 50/60 Hz 3 Hz.
(yes I know these are pretty cheap and I could just buy another hub, but Im tired of throwing things away!!!) Yep, Bobs right.. and also he did briefly mention Watts. Often a good bright light and finding the right angle to read the lettering and symbols. Now imagine you hitch the boat trailer to your bicycle. Thank you again. This Lenovo USB-C 65W AC adapter charges your compatible device to help you stay productive. Help! I HAVE A ALESIS MIXER WHICH SAYS 18V5OOmA More attention is required for those to ensure the replacement is capable of handling the throughput. This connects via a short 1-metre cable to the router by a typical 2.1 mm centre positive male connector. Wait!
Output: 48V, 0.625A. A typical power adapter takes the AC power from your wall outlet and converts it to the DC power necessary for the internal power supply of a computer or other electrical device. You havent indicated how many volts the adaptor is and in this case guessing it was 5V 1 amp. Sean, I like your explanation. Model: GTM41076-0609. P = 50 watts So a 5v 5amp transformer may put out at 8v for 0.5a load (in tech speak I think its how well regulated the transformer is). Whether you're looking for a replacement or to power your next project, Parts Express has the voltage, capacity, and tip configuration you need. Backblaze is the solution I use and recommend.
This happens if the adapters VDC is lower than the devices input voltage even when their current ratings are the same. No! Output: 12V (DC symbol) Max 1.8VA. The USB also is the symbolized for 5V voltage.

So, the wrong adapter did not actually ruin my device, but the wrong adapter itself is now dead. charger It is essential to differentiate the symbols for both types of connectors when learning how to choose the right AC adapter for your device. They don;t cost a lot on Ebay. What these outlooks dont take into account is the various protections and versatility of adapters and devices. 80w vs 80.4W is 0.4W difference.
Just set it to 10V and ensure you have the Polarity set correctly. Cheers. There would be too much guess work in most cases (for my liking). Just make sure you did your polarity test correct in the first place. My issue is well everyone in my family, phones shorting out but I dont think its from a power supply being to hi. adapter dc ac 48v prosafe 100nas netgear cord charger power APC is a well known brand. i dont know exatly what happened ro the device? It also says use only the T-T006 DC power adapter. I have a zillion power supplies too and I dont know what to do with them. I have a question and I really dont care if I sound dumb.
I have a meter so I tested your theories and this is what I found. Bought a new charger and it appears the pin is wrong size. Thank you for this article, and for all the comments! The back and side of the radio clearly say, Power Source: 7.5V 400mA AC/DC Adapter
was very low. The compressor takes 4 AA batteries and runs on a 6V A.C. adapter with a polarity of inner ring(+), outer ring(-). Match to laptop. What is the difference between an EM and Non EM adapter? I use a white paint marker (available at Walmart, Menards etc.) The adapter wires are solid black and the other is black with white strip. Battery: +10.8V 5200mAh, 56W Im shopping around on Amazon and so much items spec make absolutely no sense or are overkill.
Yes. Only states 9v DC. 1 Volt over (is probably fine). I just got an RCA 11 Maven2 Pro tablet.
Pre-qualify for up to $5,000 with no impact to your credit score.^.
Please enter values between $11 and $531. I never had to measured the the size of the connectors post, (on the male end), but Im glad this artificial brought up the issue.
Output: 12.5Vdc, 410mA. This has happened with two different boosters and a third that was another brand/unit altogether. Class 2 transformer. Well fit the mind for a layman like me. I think probably every cord that would work as far as the proper connector would carry at least 1.0 amp. A multimeter is very inexpensive and can confirm a lot of infomation that otherwise is entrusted to be accurate from potentially low QC factories. Conversely, an adapter may be rated at 5A, but can withstand currents up to 8A. You may have just extended the life of my Hoover stick vacuum (the charger is no longer available).
However, this is a big gamble. Amperage is, technically, not the rate of flow, it is the volume, or amount, of current flow. The adapter I need has an output of 24V and 12W, but the only similar adapter I can find is one that has an output of 29V and 12W. With a little skill, you could swap the wires around. The exception would be if I was replacing a cord that belonged to something that used a lot of power eg. And resistance relates to the size of the pipe. Yes, this is fine.
Do I want center positive?I am setting my adapter output on 9V (this is to charge the flashlight battery).
The adaptor can only give out 19volts but your device requires 29 volts. The advantage to this setup is that it moves the most expensive power supply components away from the rest of the DC electrical system to minimize the cost of replacement. Thank you! I have questionwhat if adapter provides an output both different i mean voltage and current??? Input: 120V~60Hz I bet the original adaptor got hot as the Zagg was utilising the full 1 amp. I have a record player that I bought in the US. Output 2 = (5V2.1A) The most important details for you and your delicate electronics are the voltage and the current.
Im overwhelmed by all these comments. Too much power generates excess heat, which is the bane of sensitive electronics. But i dont have its charger. Elaine just needs to be sure that the Voltage and polarity on her universal adapter matches that of her device and she will be fine. But, a Samsung product, The Galaxy Note 3, received a 5.3V and 2A of electricity, which received 10.6W (watt) of power.
AC alternating current, so the voltage is reversing into the plug anyway. I do have a few 4V power supplies in a box somewhere. I make a label on my DYMO label maker and wrap it around the cord for each device, paint markers that are colored work on many black things including socks.
.
You could buy the 65 watt adapter and *probably* be fine it produces nearly as much power as the original, and your device probably doesnt draw its maximum current most of the time. Output: 12 Vdc, 5 Amp. (Excellent article, btw I tip my hat to you, Mr. Busch. Depending on the region, AC input can be 110/120V or 220/240V. If you plug a 19v adaptor in, you could blow out the electronics.
