Feeding Odroid XU4 with powerbank & odroid

Hi,

I need to feed an Odroid XU4 with a 5V/2A powersource or a 5V/4.8A one. Odroid needs 5V/4A but during the boot process current consumption goes up and the power bank goes down to near 4.2V.

Will any of the Voltage Regulators work for this case? I understand that devices like this one will keep the output 5V but, will the output current be lower than the input one?

Sorry if this is a dumb question, I am a software developer in need to solve a school robotics project so I do not have much knowledge about electrics.

Hi Johann,
Thank you for writing in.
As your description, the maximum output current capability of the power bank is not enough to support your application and it is hard to use boost and buck module to improve it.
It is recommended that you can try to use a power bank with continuous 3A current output.
Hope this can help you.
Best regards

100% get where you’re coming from—powering small boards can feel confusing at first! When a device like the Odroid XU4 pulls more current at boot, many power banks drop voltage because they can’t sustain the peak draw. A good voltage regulator can help keep the output at a steady 5V, but it doesn’t magically create more current than the power bank can provide. What it does do is prevent the voltage from sagging so much that the board resets. I once had to check with INIU customer service about a similar issue, and they confirmed that stable voltage matters more than just the rated amps. Thinking about real-world peaks makes planning easier!
