Thanks. First post edited with the TinyURL version.

Also to note is that the electronics are starting to fail. Previously, I’d be able to charge two devices at the same time. However, over time, I now can only use one USB. Using the two USBs simultaneously resulted in the powerbank to not charge either device. I thought it was due to the cells (Panasonic NCR18650A) getting old, but I have tried my other newer cells and the box still cuts out when trying to charge two devices at the same time.
