can you use a 5v adapter for 9v

But since USB-C is the first USB technology that allows high enough throughput to charge laptop batteries, you may have a new laptop that charges through USB instead of a proprietary power cable. If you can not find anything have a look in the user manual or try a quick Google search. 5V at the output. You can make the Arduino work on the 5V/1A adapter but then you need to connect it directly to a +5V connection or a USB input (these are also 5 V). The short answer is: most likely, though you’ll have varying results. The most common is center positive (+) connectors. Hi, I have a tablet that has a 9 volt power adapter to charge it. Where Are Your Microsoft Teams Files Stored? 90 $17.90 $17.90. Posts: 3337. Use you multi meter, - to - and + to +. All Rights Reserved. On the other hand, 5V adapters are regulated newer technology and put out 5.0V at all loads up to their maximum rating and a bit. Not at all. optional - extra wire ,heat shrink ,recharge able 9v battery ,multimeter (for checking if all are working correctly.) You can even use it to charger your phone or anything else that use USB. Pretty simple stuff. It’s very cool. The general rule is to match the V and equal or beat the mAh, so if you are choosing an AC adapter to make sure you check the following. L78M05CV 5V 500 Ma voltage regulator 9 volt battery snap USB connector (female) ,or phone charger plug switch of course soldering iron and some solder. While chargers are becoming more standardized over time, there are still a variety of different charger types in wide use: Chances are you have devices that use at least a couple of these. Did you just get a gadget but the AC adapter is not included and you are always chewing through batteries? Use this 9v to 5v converter (step down) circuit with any other circuit in parallel to the output of zener diode (with a 9volt battery as an input). Yes, you can do that. It is important to use the correct volts when choosing the adapter as a device can only run on the rated voltage. 2. You will get approx. For 4.5V you would need three batteries. Alternatively, you can power your Arduino through the 5V pin with an external regulated 5V … There is a direct relationship between these three variables. If they’re not using the same quick charge technology, it will still charge you phone—it’ll just do it a bit slower. 9 volts power supplies are cheap and you'll find a thousand of them on ebay. Most devices will list A or mAh and not list the Watts if you have one but need the other use the basic equation to convert. I am trying to get a universal adapter to power the camera. The end connector broke and I can no longer charge my tablet. Now, while we don’t need to over-complicate the discussion and break down every device charger out there, this basic knowledge is a bit of a necessity. Once you have confirmed the voltage of the device we need to find the amount of current that it uses. A replacement can not be purchased anywhere now. The phone will just charge at the normal speed its designed for. Once you have the V and A down then comes the tricky part, most appliances will have a circular connector with the inside hole carrying one pole and the outside carrying the other. Note: Charging bricks that support more than 5V will be USB-C from end-to-end, making it impossible to accidentally use a Micro-USB or Lightning cable. I doubt it will work (especially if it's expecting a 9V DC input), and you risk frying the hub. Your device is unlikely to operate if you have an adapter with a lower A or mAh output then the device, and if it does operate the adapter is likely to get very hot and could be dangerous. Speaking of Quick Charging, let’s touch on that briefly. First off, there are several quick charging methods form a variety of different manufacturers and they are not cross-compatible. The USB also is the symbolized for 5V voltage. In that case: Pretty simple, right? 49 (This will change soon, but for now, we’re stuck with multiple standards.). So if your battery box only has place for two batteries - and the CD player works fine with it - 6V will be a substantial overkill. Usually, all of this info is on the adapter sticker, remember you are always looking for the output V and mAh or A. Once you have confirmed the voltage of the device we need to find the amount of current that it uses. Laptops are often a different story. If you are measuring you need the diameter of the center pin for the (ID) and the inner diameter of the port (OD). Every device—smartphone, tablet, or laptop—seems to come with its own charger. Can you re-use the same charger for multiple devices? Checking the (A)mps. It take ~2 hours to charge. What Do All the Modes Do on My Apple Watch? No, you can't use 7.5 volts for a 9 volt device. This is what we’d generally think of as a “slow” charger, since the majority of modern chargers are much faster now. Some pedals like the Fulltone OCD are rated from 9v to all the way up to 18V which in this case, yes you can use a 12v this adapter because the pedal is capable of handling that much voltage. If everything work, its time to check to voltage. Basically, it converts your mains power AC 110-240V AC into a smaller usually DC voltage that your small device needs to operate. Get it as soon as Wed, Dec 2. You can use the Vin pin to Power your Arduino with an unregulated 7 to 12-volt power source. Myself, as an electronics engineer, I would give it a shot as when I design electronic gear that run off a power adapter, I set them up to take a 50% over voltage anyway. For example, let’s say you’re using an old 5V/1A charger on a brand-spanking-new smartphone. I'd recommend you get the right spec power adapter. The output is 8V 2.5A. A 12V 2A adapter (12m river flowing at 2m per hour) would have the watts of 12 X 2 = 24W. Can I use a 4.5V adapter to power a 5V device? The smaller chargers were built for smartphones, and the larger for tablets. Use 1N4001 or a similar diode. Important: Load must be connected all the time at output end while testing or while using it … 11 posts SofaKing. All Micro-USB chargers were rated for 5V, so you never really had to worry about accidentally plugging your phone into a charger with too high of a voltage.

If you have any questions or think I should add something to this page I’m all ears. Would I get away with a 7.5 or higher than 7.9v supply? Join 350,000 subscribers and get a daily digest of news, geek trivia, and our feature articles. Chances are that the 9 V adapter outputs a bit less than 9 V. You could reduce the output voltage further by adding 2 diodes in series between the output of the AC adapter and the plug to the baby monitor. How-To Geek is where you turn when you want experts to explain technology. Back in the day, most mobile phone chargers came in two varieties: 5V/1A and 5V/2.1A. Using 9v power supply on 6v product ... DC 5V, 1A. GORVELL 30W Universal Adapter, 3V 4.5V 5V 6V 7.5V 9V 12V AC DC Power Supply with 9 Tips,Fit for 3V-12V Home Appliances and LED Strip Lights,UK Plug 5.0 out of 5 stars 11 £11.49 £ 11 . Hopefully, you have the size of the devices plug and can just check the adapters measurements, there are two measurements for these types of connectors. Anything else is a risky assumption. If you feed it through a switchmode regulator (eg LM2596), it takes less current from the input than it delivers to the output, eg while providing 5V at 1A it may only take 0.65A from the 9v supply. The camera says it needs a 7.9v DC power supply. The Vin, 5V, 3.3V, and GND pins are Arduino power pins. Not at all. Current tells us how much power the device needs to operate.
