GINTOOYUNDC Y Splitter Cable 1 Male to 2 Female,5.5mm x 2.1mm DC Power Extension Adapter Cable,for CCTV Surveillance Cameras,Surveillance Routers,DVR,and More（2PCS

did exactly what i needed it to do.

I really like the snug fit to other devices, good to keep the connections from opening up. Don't know about the internal construction, but they are flexible and seem fine so far.

Saved my Christmas tree lights with 2 off these!Excellent quality!

Just a little thin wire.

Pros: 2 packs and good qualityCon: It could be a bit thicker for better signal, power/noise ratio

These don't seem like terrible cables as long as you read the specifications and noticed 24 gauge wire. While that may work for your application, some products using 5.5mm barrel connectors consume more current than 24 gauge wire is good for. 3 amps rapidly magic-smoked these for me, so they're only good for a fraction of that.

It works for its intended purpose.

These cables failed within a few days of very moderate use.

Good quality

Same as the description.

One of the few Y adapters where you have 2 female going into a male. Use it to connect 2 solar panels in parallel into a charge controller. So I am using it as a joiner rather than a splitter. Functional and as described. However, the wiring might be a little thin for high current applications and gets a little warm, nothing crazy dangerous around 10A, but definitely warm to touch. If you sending more than say >12A (6A per Y's split), you may want to reconsider.

One of the two did not work on one side of the split.Kind of hard to complain given it's like $10 for two. But if it's critical, buy more than you need.

I bought this 4 months ago and only testing it now.I purchased two of these Y-splitters.Both are not wired correctly as the ground is on the center pin of one endand then switches to the outer pin.I likely received the reject pile.Test this immediately as they only offer a 30 day refund.
