I lost the dc adapter to my irulu expro x11. Unable to find the specific one. Would an adapter for the x1 or one that has several little plugs for it work?

There's 3 specs you need to match. First, there's the size of the plug. Next, there's the voltage. Then, there's the current. The voltage should be listed on the expro, along with the current required. The voltage should match, but the current for the adapter is the minimum you'll need. From the IRULU site, the charger is 5Volts DC and supplies 2 amps, so if your other charger supplies 2 Amps at 5 volts DC, it should work, if the tip fits. More than 2 amps will work. Less might not, or will charge it slower. The USB cable can also charge it, but usually takes a long time, and can not supply enough current for continuous operation, so the battery will drain in use. It can take half a day or more to charge it through USB on some models. The multi tip adapter can work if there is a tip that fits, but make sure you select the proper voltage, 5 volts, and watch the polarity, as the outer ring can usually be set for either positive or negative voltage. iRULU eXpro X1Plus 10 1 inch quad core tablet Android 5 1 Lollipop support...

Hi, i need to know the exact power plug so i dont have to run the pedal on battery power.i know i need a 9v power supply but i dont know the size of the jack that goes into pedal..many thanxs..

Unfortunately, battery jacks and plugs similar to the type you're describing do not have any real standardization - unlike the outlets and plugs in homes and businesses have.

You best bet is to either bring the plug / jack to a shop to match it or contact the instrument's manufacturer to obtain the connector specs for physical dimensions

Be sure to obtain the power requirements in either watts or amps so that you can obtain a power source capable of delivering what you need without overheating during longer periods of use. Adding 25% to 50% more amps or watts to the minimum required should provide years of trouble free service. Example: 9VDC at 50 watts should be supplied by a 9VDC 62 watts or even 75 watts; or in the case of a rating of 9VDC at 6 amps should be supplied by a 9VDC at 7.5 amps or even 9 amps. With DC powered devices, make sure you observe proper polarity! Good luck!

Model lc 8460btx power supply how to convert to dc for car amp

There's a few options. I would say the quickest would be to buy a "Inverter" this will take 12-15VDC to 110VAC. Walmart sells these Inverters. I would say buy the highest wattage Inverter you can afford. I would say a 500W Inverter at a minimum.

I have a Maxtor external driver and the AC adapter is not working. I need a new AC adapter and local stores do not have it. How can you help?

There are "generic" power supplies that might meet your needs.

This is a response I gave to another user who had a different external HDD and needed a power supply.

The hard drive unit itself should be able to supply you with the required DC input voltage (hopefully there is some kind of label on the enclosure).

You could try one of these or something similar. It comes with 6 interchangeable heads and has adjustable DC voltage. This is just one of many available.

I cannot guarantee any of these supplied heads will fit your particular drive (same with the dc voltage). Some local retailers
often have these types of adapters and you might be able to determine what size you need by looking at one. Most of the

Externall HDD need 12VDC and 18+ watts of power.

Here is an online site also.

I have used DC units similar to these in the past when I have lost a power supply.

Hopefully with a minimum of effort you can get a working solution.

How can I operate my LG 26LE5300 LED LCD TV in my motorhome the most direct way possible (i.e....without an inverter)? This low power (40-50 watts) TV has an external brick to convert 120 AC to it's...

1) You need to look at the output current rating (AMP) of this AC to 24dc adapter, this 24vdc adapter is a regulated switching power supply that will maintain 24vdc output up the maximum current rating and also has shutdown circuits if the over current draw is detect and also if the output voltage goes up beyond 24vdc to protect the load (TV).

2) To use 12vdc to 24vdc DC-DC booster, it should have the following spec:

A) The output current rating should be at least 20% higher than the load requires to give its head room.
B) It must have regulated output that will maintain the 24vdc when the input (12vdc) will vary from 10vdc ~16vdc or higher since your batteries will not maintain exact 12vdc all the time.
C) It must have good protection circuits that will protect it self from reverse polarity connections, shorted output protection, over voltage output protection.
D) It should provide AC ripple spec on the 24vdc output, it should be in the milli-volt range (you will always get AC ripple riding on top of DC when you rectify the AC into DC).

These are the minimum requirement for your DC to DC booster, which you need to protect your TV and your motor home from burning down.
I hope I explain it OK to you.

Please leave rating if it helps.

Basic troubleshooting guide here:
Failed TV and Monitors:
Learn about bad caps:
Capacitors kit: he can make you a set of caps.
Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
Please leave rating if it helps.

I'm trying to determine which AC/DC adapter to use with this device. Apparently the VDC should be 5-9V, is there a minimum/maximum current that you are aware of?

500ma (1/2 amp) should be fine.. It's imaterial if amp rating on power supply is higher, as the device will only use what it needs. A higher amp supply will simply run cooler as it not being demanded to run at capacity.

Need power supply spec's for this WD25001032 hard

If you can procure it you need a "Wattac" AC adapter
model: BAO362ZI-8-A01 (made in China)

Otherwise you need a 12 volt 2 Amp. power pack with positive on centre contact & 2mm pin hole.

We need a power supply for the A170E101-how do I order or do you have retail outlets for this Thank you...

You need to look at the back of the monitor for the voltage (DC) and current (in Amp) requirement. You have to get the right voltage, but the rating current of the power supply can be higher but not lower, i.e 12vdc 5amp power supply can be used in place of the 12vdc 4amp supply.
Then you need to find out what type of DC plug is needed, most monitor uses what they call barrel type, most common are 5.5mm OD x 2.5mm ID, or 5.5mm OD x 2.1mm ID.
