What is Birdcord?
A Birdcord is a voltage converter cable that converts the voltage of a USB outlet to fit your audio device. There are four different versions: 6V, 9V, 12V and 18V.
Can the Birdcord power my device?
Birdcords can power most guitar pedals and many other DC devices like keyboards, battery amplifiers, loop stations and more. More specifically it depends on the supply voltage (V) of your device, the current draw (mA), the plug dimension (i.e. 5.5×2.1mm) and the polarity (center positive or center negative). I usually get these specifications from forums, operating manuals, the power list, or by measuring. Get in touch if you have any questions (firstname.lastname@example.org).
Supply Voltage: The supply voltage (V) of your device and the Birdcord output voltage (V) must be identical. (Slight differences are okay: It’s possible to power 5.7V devices with a 6V Birdcord)
Current Draw: The permanent current draw of your device shouldn’t exceed 80% of the maximum current draw of the Birdcord. Current is measured in Milliampere (mA). Instead of current draw manufacturers often rate the power consumption (W or mW) of their device. You can divide the mW-rating by the supply voltage (V) to get back to the mA-rating (mA=mW/V).
Plug Dimension: The plug dimensions of all four Birdcords is DC 5.5×2.1mm. It’s the most common plug dimension. If your device has a different plug (jack) dimension I probably offer the correct adapter.
Polarity: The polarity rating tells you if the positive (+) or negative (-) electrical pole is in the center or on the sleeve of the DC plug or jack. The Birdcord’s polarity has to match the polarity of your device. In case it doesn’t, you can easily change it with a polarity inverter.
What separates the Birdcord series from other voltage converters?
Birdcords are designed for audio applications (noise-free!) and for the use with USB power banks. This means that they avoid the power bank from shutting down at high startup currents of big devices (portable amps, keyboards, big digital pedals) as well as avoiding the low-current shutdown of power banks for smaller devices (like analog guitar pedals). The use of high-quality components ensures longevity and market-leading output power.
Which USB power bank should I get?
For best results choose a USB power bank with an output current of at least 2A. Even better would be 2.1A or higher. I have good experiences with power banks from Anker, but other manufacturers will work too.
How long can my device be powered from one charge?
TIME [h] = POWERBANK CAPACITY [mAh] * 3.7 * 0.8 / (CURRENT DRAW [mA] * SUPPLY VOLTAGE [V])
Example: The Boss RC-1 loop pedal draws approximately 100mA of current at a supply voltage of 9V. My power bank has a capacity of 10.000mAh.
=> TIME = 10.000 * 3.7 * 0.8 / (100 * 9) = 33 hours
Can I use a USB power bank with two outputs to use two Birdcords at the same time?
Yes, with reservations. Usually, it works perfectly fine. Technically, you are creating a ground loop by doing this and this could cause noise, but usually, it just works. By using a 5-way daisy chain adapter or a 2-way dc splitter you can power more devices from only one Birdcord.
By using a second power bank you can create an isolated power supply, in case you need it.
Can I use a USB extension cable between Birdcord and USB outlet?
No, don’t do this! It puts a huge impedance between the USB outlet and the Birdcord. This will eventually damage the Birdcord. It’s better to use an extension on the output side of the Birdcord. A 5-way daisy chain adapter or a 2-way dc splitter can act as a suitable extension.
Can I use a USB meter between Birdcord and USB outlet to measure the current draw?
No, don’t do this! It puts a huge impedance between the USB outlet and the Birdcord. This will eventually damage the Birdcord. Besides, the current you are measuring in this spot is not the same as on the Birdcord output due to different voltages.
Can I use the Birdcord outside?
Yes, in combination with a USB power bank the Birdcord allows you to use your audio devices anywhere you like. Keep in mind though, that direct sunlight on a hot day can lead to overheating of the Birdcord and the power bank, especially when you draw a lot of current.
Do you ship to my country?
Yes, I ship worldwide. Find more information here.
Have you already shipped my order?
Currently, I ship orders twice a week. You will receive a confirmation email on the day of shipment.
Can I get a tracking number for my order?
In most countries I offer priority shipping without tracking number, to keep the shipping cost low. Your order will arrive in your mailbox just like a letter. In some countries, I offer registered priority shipping with a tracking number. In case your order says “Registered Priority” you can contact me for your tracking number.
Where is Songbird FX based?
