14 best adapter with ac powers

An AC adapter, also known as a power adapter, is a device that converts AC power from an electrical outlet into a lower voltage DC power suitable for powering electronic devices. AC adapters are commonly used for various electronics, including laptops, smartphones, tablets, and other portable devices. They come in different shapes and sizes to accommodate different devices and power requirements.

AC adapters are essential for charging rechargeable batteries in electronic devices. When connected to a power source, the AC adapter provides the necessary power to charge the device's battery, ensuring it remains operational when not connected to a power outlet.

These adapters typically consist of a plug that connects to the electrical outlet and a cable with a connector that plugs into the device. Some adapters have interchangeable tips or connectors, allowing them to be compatible with multiple devices. The voltage and current output of the adapter must match the requirements of the device being powered to prevent damage.

When choosing an AC adapter, it's crucial to match the voltage, current, and connector type with the requirements of the device.Using an incompatible adapter can damage the device or the adapter itself. Additionally, some adapters come with additional features such as built-in surge protection or energy efficiency to enhance the charging process and protect the connected devices.

In summary, AC adapters play a vital role in powering and charging electronic devices, ensuring they remain functional and portable. Proper compatibility and usage are essential to prevent any damage to the devices and adapters.

User questions & answers

Question: How do i know if my tv has a powered usb port? if your tv has a usb port does that mean it’s a powered one
Answer: The USB port on your TV will provide power. But you won’t kbow until you try it with the fire stick to know whether or not it has SUFFICIENT power.
Question: Does this work with Echo Auto
Answer: Hi! This is made to work with the Amazon Fire TV 4K.
Question: Other than the shape, what is the difference between this and the fatter-looking one for fire tv stick
Answer: The stick model has a 500mah battery, this model has a bigger 2000mah battery.
Question: Is this necessary? i have a fire stick 4k that i use a generic micro usb cable to power directly from the tv. what does this product do
Answer: I bought this based upon the Reviewer from Dec. 29th 2019's feedback and discovered everything they said is wrong. It does not keep the Fire TV Stick powered when the USB Port on the TV is turned off. When I purchased this unit myself I charged it via a standard USB Charger Block as the instructions said that any USB charging source could be used and after hours of charging decided to move it to the TV and I powered up everything and watched TV for another few hours and decided to test the unit by turning off the TV for a few minutes and noticed that the Blue dots on the device went out immediately and after 3 min. turned the TV back on and the Fire TV 4K Stick did a cold boot! The battery inside this device doesn't keep the Fire TV 4K Stick powered at all when the USB port is turned off. I don't see any reason to own this device as I have a USB 3.0 port on my Samsung TV and it seems to power the Fire TV 4K Stick just fine! I play 4K Ultra Content all of the time and have not seen any issues previously so maybe they are talking about very old TV sets that only had USB 2.0 ports? Otherwise, save your money.

User questions & answers

Question: Will this power my alesis forge drum kit? it need 9v dc in (500ma
Answer: The unit has a variable voltage output and one of the settings is for 9vdc. The maximum current is stated as 3 amps so 500ma should not be a problem. The only question would be about the plug end on the charging cable. It comes with 8 different plug ends to adapt to most any standard charging jack. I haven't had a problem using this charger with a number of devices using many different plug in jacks.
Question: Does one of the tips allow connection to a distribution block
Answer: NO! It doesn't.
Question: I understand voltage can be changed by rotation. what about ampere? what does 3a max mean? it'l automatically adjust ampere depending on device
Answer: Yes, you are right. The output current is automatically adjust ampere depending on device. If your device only needs 0.1 amp. This AC adapter only delivers to 0.1 amp to your device. Max. support 3 amps.
Question: My device shows "+"on the left and "-" on the right, which seems like "inner positive, outer negative". Is that right
Answer: If the + sign is on the right, then the device has positive polarity. If there is a – sign on the right, then it has negative polarity. A positive polarity means that the center (also known as the tip) of the output plug is positive (+) and the barrel (ring) of the output plug is negative (−). That would seem to correspond with your "inner positive, outer negative" question. The symbol for positive polarity looks something like this: O----C----+; only there would be a negative sign inside the solid circle on the left, a dot in the middle of the open circle (the "C"), and a solid circle around the plus sign on the right. A negative polarity would be the reverse, like so: +----C----O.
Question: is it two prong or three prong? can't see it in the picture
Answer: It's actually made to be plugged into a grounded wall socket, replacing the 2 3-pronged outlets with its 6 available grounded outlets. It can even replace the outlet cover and be screwed into place. I've got a bunch of these and love them.
Question: What are the actual dimensions of this unit
Answer: against the wall, mine is about 4 inches wide, 4 3/4 inches tall, and about 1 3/4 inches deep
Question: Will this work with half-switched outlets (where one outlet is always live and one is switched), or do all the outlets get power from only one outlet
Answer: All power for this device comes from the TOP outlet of your receptacle -- so if that is switched then all outlets on this device will be switched (or if your bottom outlet is switched then all outlets on this device will NOT be switched).
Question: Can this actually completely replace the existing outlet wall plate, or does it only plug in/screw on TOP of the wall plate
Answer: This can replace the existing wall plate -- that's how I am using it.

User questions & answers

Question: Has anyone tried this with the R5 yet? Price is appealing but not sure I want to risk it with such an expensive camera
Answer: That not a question, but I'll turn it into one and try and answer that question that I just wrote. "Why do I get a humming noise when I plug my planet waves adaptor into a mini twin fender amp?"First off, does your mini twin work with a nine volt battery? Check that. If not, then the amp's broken. If yes, continue. I just checked, and the mini twin seems to be center negative, like the adaptor. Still, check to see if your mini-twin power in is expecting a center negative power supply.Perhaps the power supply input jack on the mini twin is broken?Perhaps you've gotten three bad power supplies. Have you checked them with a multimeter?Good Luck.
Question: The battery pictured is not the lp-e6 battery which has two contacts close together on the same side of the battery center line. what gives
Answer: They've updated the product at least once now, it seems. I have three I've bought from Amazon with 2013 copyright logos on the bottom, that have "Regulated" printed above the large "ADAPTOR" verbiage, have a 300mA rating, and are a larger cube shape and are much heavier. The revised version drops the 'regulated' verbiage on the box front, has a 2018 copyright, has a 500mA rating, is a rectangular shape like in the current Amazon photo as of 2020, and is MUCH lighter in weight. Both have the exact same model number PW-CT-9V, and UPC code 0 19954 95097 2.
Question: Does this work with the eos 80d
Answer: It is not attached when shipped. I must be screwed in place, So, unscrew it and remove. The screw even has a flip up wire making like a wing-nut to make this easier.
Question: What does "fully decoded smart chip" mean
Answer: Yes

User questions & answers

Question: Will this work for a kid's power wheel four wheeler charger? The four wheeler required 12v 1000ma charger
Answer: Hi There. This depends on the polarity of your original charger, this one is Positive polarity(+) only. About two year ago, one of our customer purchased our 12W adapter for "Mercedes Benz 12 volt ride on toy car", later found it did not work. After several emails with this customer, we re-sent the negative polarity one and solved this problem. So please check the device polarity, it's very important.
Question: Can you return this
Answer: Yes, you can return this item within 30-days.
Question: Will this work for computer speakers? I know it says bt speakers, but I don't even know what that means
Answer: Hi There, The bt speaker is for Blue Tooth speaker. Generally speaking, if your computer speaker is under or equal to 12V 1A Output load, it would work. It's important for us to check the device DC Output, which you can usually find the specification near the charging port.
Question: Is the center tip positive or negative
Answer: Center Positive(+) only.

User questions & answers

Question: which adapter do I need for 110 v ac to 12v dc 2.5 a
Answer: Range Compatible: 9V ( 100mA - 1500mA ) .
Question: compatible power adapter for MDS4001 blood pressure monitor
Answer: No, because the Digitech RP500 requires 9V AC, and this unit supplies 9V DC. It also will not work for effects requiring a Boss type 9V DC adapter, as the polarity is the opposite of what those effects require (i.e, barrel positive, center negative).
Question: What is the tip polarity or how do you change the tip polarity
Answer: This power adapter cannot be used in Australia.
Question: Will this work with an auvio 3.5" portable hdtv, model (catalog
Answer: Yes, since Amazon offers free return on this item I decided to try (OEM too expensive). I have the PT-2040 and it works perfectly. No more batteries. :)
