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). 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. Once you have confirmed the voltage of the device we need to find the amount of current that it uses. Even if it did work at first, the hub is likely to overheat pretty quick. Another thing to note: Most digital devices today that run off 5V feed that rail directly into a voltage regulator which drops it to 3.3V or lower. If we look at the river we could calculate how much water is flowing into the river per hour. That means just because your device supports some form of “quick charge” technology and your buddy’s charger does too, you can’t automatically guarantee you’ll get a faster charge. So thats it! I do, however, have a 5 volt power adapter with an identical end.

If you have any questions or think I should add something to this page I’m all ears. That answer is…well, maybe. If you go into a shop you can compare and test the connector size, or if you are technically minded you can measure the size of the port and pin yourself. I would not chance it but it might work. Giving a pedal more voltage to play with (18v instead of 9v) will typically provide a larger range of headroom before the guitar’s signal starts to clip. 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). 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. Important: Load must be connected all the time at output end while testing or while using it … There is a direct relationship between these three variables. It may even worse when the converter is unregulated. With larger device batteries, new charging technology like Qualcomm’s Quick Charge, and formats like USB-C that allow for better charging throughput, chargers are more complex than ever. If everything work, its time to check to voltage. A 9v 600mA adapter will deliver 9v at up to 600mA. 1. 11 posts SofaKing. To understand charger compatibility, you first need to understand how they work—at least on a rudimentary level. I am trying to get a universal adapter to power the camera. Those devices need the input voltage to be a little higher than the target voltage, so maybe 3.6-3.9V at a minimum. If you are not sure on the pin type or are looking to use it for a few devices then make it easy with a universal adapter, they allow you to have different voltages, polarities, and connectors. – Bimpelrekkie Dec 3 '15 at 7:49.
