Review on 🔌 Long Cable T Type 9V Battery Clip Connector - 10 Pack, Hard Shell, Black/Red by Jason Camarillo

I bought these connectors to connect multiple 9V batteries in parallel to get 4x longer battery life. The 9V DC combo voltage is used to power my BOSS micro recorder instead of a power adapter that needs to be plugged into an outlet (not very portable). With this power supply, the BOSS recorder stays on until I manually turn it off. I usually use 2 AA batteries that go into the recorder, but the recorder will turn off automatically if left unattended for a while. And it may take 15 seconds to turn back on for recording, i.e. H. missed most! Today I put together a pack of 4 rechargeable 9V batteries connected in parallel. Just take a look,
