USB 5V 2.1A adapter for crowdfunded Lockitron


I had connected my crowdfunded lockitron to a USB 5V 2.1A adapter, it worked well for few months. Last month, it suddenly could not work, I removed the USB adapter and put batteries back to lockitron, it worked normally again.

I tried to check my USB adapter with voltmeter, it normally gave me 5V and 2.1A. Why my lockitron worked with USB adapter for few month, but suddenly cannot work now? Do you think I need a more powerful DC power source?

Thanks a lot!


@hkjosephng that’s probably powerful enough. Unfortunately there is an unresolved bug with the crowdfunded Lockitron whereby the memory corrupts and you need to pull and replace a battery in order for the unit to update.
