Perfect if you’re charging up light up sneakers

I bought these for a self-supported multi-day road bike ride. There's not a lot of space for a bunch of chargers when you're living out of a trunk bag and a top tube bag. At the same time, you want to keep a bunch of things charged without having to babysit them and swap a single charger after reach day's ride; a pair of tail lights, a pair of headlights, a bike computer, a phone, etc. Doesn't take much juice, so sharing a single port in a USB power plug between four lights for an overnight charge is fine. Two of these, one USB-C cable for my phone, and a 3-port plug let me start each morning with everything fully charged while taking much less space than if I'd needed to bring 9 ports worth of USB power plugs and as many cables.It's worth noting that a split cable like this isn't going to work for multiple devices that need to negotiate the higher power levels USB can support, since the power supply doesn't expect multiple devices with different power needs on a single port. So you're only going to get 5v, and however many amps the port can supply will be shared by all the connected devices. Some devices might not charge at all, and many will charge slower than they could. But for overnight charging of mostly devices that don't take advantage of higher power USB modes anyway, these are great.

I used it 2 times and the 2nd time 3 out of 4 worked.

if you have cabinet pucks its annoying to have them die at different times but even more annoying to find cables to charge them all this is the simplest solution. It feels a bit flimsy but its working perfectly a month later.

Works the way it is supposed to.
