I just bought the knock a few days ago Thanks for the review

I just got the light as a free tool from home depot. I'm very happy with it. Thanks for the vid!

One important note, the real Milwaukee M12 Power Source (48-59-1201) has QC spoofing meaning the USB port can output 9V @ rated 1.6A. I've actually tested this and found it does indeed do 9.xxx V at a real 1.6xxx A reliably, meaning almost 15W charging on a phone that has QC charge compatibility (or any of the cross-compatible protocols). This means it can charge a lot of phones with a decent degree of "quick charging" which is more important for modern phones than the 5V output. Most USB A ports on these type of devices never give the rated current anyway (sometimes nowhere even near--I have some power bars that have ports rated for "3.4A" that can barely break 1A of actual output), so the 5V not being 2.1A isn't really a huge deal (5V @ 2A is still only about 10W). Though QC spoofing is easy, I've rarely seen many A ports on similar devices that have this. I don't believe the Rover light has this either--it's 5V output only. That said the M12 Power Source is *way* too expensive on its own--it's like $80 CAD over here when you can get one within a heated jacket package, with a 2A battery and of course the jacket, for around $200 CAD. There's no reason the power source on its own should be more than $40...but that's Milwaukee for 'ya! A USB-C port with PD would be most ideal of course, but for most power tool "power sources" we'll probably have to wait for the newer gen products for those. Some inverters have them though... The M18 Top Off inverter has the same QC-capable A port plus a 45W PD-capable C port. Ryobi's 40V inverter has a C port with PD as does their unobtanium new-version ONE+ inverter (this was advertised like over a year ago, still haven't seen it actually for sale).

I was going to ask if the knockoff did balance charging, but based on the missing pins it obviously doesn’t! I would be very hesitant to use a non-balance charging charger with any regularity. Maybe for infrequent emergencies? I was thinking it would be a nifty thing to keep in my car in case I needed to use a tool for longer than usual. But that charging rate is so slow and the lack of balance charging means I will skip it for now. Thanks for the great teardown!

🤙🏼thank you I did

I would not get the cheap one to charge but as a cheap power bank i think it is alot better for the price.

By chance did you get any temperature readings on the knock off one? I’ve heard the knock off charges get super hot or catch on fire

Could you compare the barrel jack output on the knockoff vs milwaukee. Does the knockoff have undervoltage protection?

If you own a Milwaukee or Dewalt heated jacket since you have the adapters can you tell me if there compatible in each other? The Dewalt power stack battery allegedly has a significant better run time I’d like to try one in my Milwaukee jacket to test it.

Campers might use the adapter for charging an M12 battery in the car. The fake adapter is dangerous because it does not prevent over-discharging. Lithium cells discharged below the minimum safe level and can vent or explode. Stay away from anything that discharges cells below the minimum safe level. It is not worth the risk.

YOU GET WHAT YOU PAY FOR

The knock off may burn your device/$1000 Iphone because the electronics is not as good as the M12.
