iJiZuo OTG Micro to USB Adapter (4 Pack), Mini USB Male to USB 2.0 Female OTG Adapter Converter, for Tablet, Smartphone and Other USB Devices - Silver

These are really helpful when you're trying to connect a device to a raspberry pi zero as they only have the micro USB sockets and most devices require a full-size USB. Although they are quite wide, they do fit and as long as you don't have a wide power cable (as in a thick micro USB) then they fit perfectly. Another important point is that the full size USB is firmly fixed in and doesn't fall out.

1 isn't working. The rest are loose. They do work and as long as you don't make any movement they'll keep connect. With the slightest bit of movement they'll disconnect. Useless unless you are attaching to a phone that won't be moved. So no good for file transfers or much else really.Save your money.

Was searching through my cables and realised I need adaptors to join some of my items from charger to and didn't have the right adaptors for use in my car, good items and do the job perfectly.

I hadn't realised that all 4 were the same, I thought they were assorted for different phone sockets so no good for mine

PACK OF FOUR - ALL SAME, NONE WORK. PURCHASED ONE ELSEWHERE, WORKED PERFECTLY.

Did not fit. Supplier did not offer any help.

All good
