has anyone tested if it is 5v and not a mislabeled 12v?

Hello Dear ,this adapter is DC5V ,not 12V .Best regards

How many W2812B strips can I connect together with this?

All depends on how many LEDs/what brightness/which color for each LED. At 5V, each LED draws about 50mA, when set to its full brightness.

is this the correct power supply for btf-lighting ws2813 16.4ft 60leds/m individually addressable rgb led flexible strip light 16.4ft 300leds?

DC5V6A 30W is OK for WS2813 16.4FT 300LED LED Strip . But we recommend you light up some chasing color lighting effects .Light up 1 color（red or green or blue) 0.1W/LED . Light up 2 colors (red+green) 0.2W/LED , Light up 3 colors (red+green+blue=mixed white) 0.3W/LED .Please don't light up mixed white . Any other question , please contact us support@btf-lighting.com Best regards BTF-LIGHTING

Does the 5v10a power supply maintain 5V constant even at 80% (8A) output or does it drop below 4.7V?

I don't know for sure. However, if your standard split system 200 Amp service fails, you have a lot bigger problems than fluctuating voltage converted by this power brick. The only way your question could be answered would be to test it in person. But you could only do that if you purposely dropped the source voltage by 20%. You could do that, but I think it would be a waste of time. You would need some type of voltage regulation equipment, and the test would take a lot of time to set up. The bottom line is, most American (utility provided) residential power systems provide consistent voltage/current outputs to homes that are not going to fluctuate 20% (so that you are left with 80% output).

missing adapter *edited*

The whole reason I ordered this one is I didn't have to splice and solder. The adapter was missing. EDIT- I ended up just splicing it and it actually worked better wo the adapter plus customer service reached out to me. I'm running this power supply at 7 amps running 5 m strand of WS2812 LEDs with wLED and it seems to work fine. SECOND EDIT 7/21/23 I ordered a second one to power A second set of lights, and this thing whistles a little bit. it's not extremely loud but you could hear it if you're next to it so I checked the first one I bought and that one makes a slightly different whistle noise and not as loud but it's still there. The first one I had has been plugged in for over a week and it's not hot, the outer case doesn't get above 77° f, so I don't think there's anything wrong with them but I just think it's odd that they whistle like that. maybe all power supplies do I don't know. I'm not changing my rating because they seem to work fine, I've had no problem powering the LEDs at all different amperage settings.

It powers them and that's all I can ask for!

I bought this to go along with my controller and BFT led's. It powers them and that's all I can ask for! It's pretty small considering, but It doesn't get warm at all. Install is easy, just plug it in! Great value.

Power need more power!

It worked great for my first set of 16.4ft of WS2812B led strip lights. It continued to work well for my second set now 32.8ft. However, when I connected a 3rd set only about 2-3fr would light up. I hooked up to the first set to test the strip and all of the lights came on. I'm not an electrician but seems I needto find more power.

Quality power brick

This power brick works great for my latest LED project which requires about 9.5 amps at 5v. It has a solid build quality and a decent length cable going to the barrel plug.I highly recommend this product.

Know Basic Electricity Before Using

Have two 10As for two different 200 LED strip setups and one 5A for a 60 LED setup - all planned properly.You obviously shouldn't use the supplied female barrel jack unless you're pulling MAYBE 1Amp (if that?). Know what minimal wire AWG you need, where, and be mindful of power injection placement. Even consider inline fuses.If you don't, yeah, you're gonna have a bad and mighty hot (not bright) day.

Works as expected.

So far it powers my lights and runs cool. It's heavier than expected and seems nicely made.
