I lost the cable of a baby bliss trimmer. They have proprietary plugs that are about the same price as the trimmer. Moved away from them when ASAP...

Coincidentally, I just got a knock-off Soda Stream from Phillips. It's over $150 cheaper and works 2x-3x times better. I wanted to build something similar for a homemade soda bar concept, and discovered how truly cheap it can be to make soda and carbonated water at home. I was shocked at what a simple concept it is, and how much of a profit these sodas water companies make. Phillips even charging $50 for their system is a total rip-off.

Truthfully, I think the increase in quality in the Phillips machine is due to fewer parts is an "exception that proves the rule" as these in-bottle carbonators seem to work better with fewer parts. It's just a pressure hose connected to a co2 tank. Literally, all of $6 if you were to build one yourself from parts on Amazon (or $3 if you got he Alibaba route)

I truly believe that the fewer parts the better in any DIY or commercial product due to the less chance of a failure in a part if there are fewer parts. This works fantastically for the "lower quality" producing companies, like Phillips.

My inventive and engineering entrepreneur friends and I call this "fewer parts the better" concept, a "Murphy's law compensator" as the fewer parts there are, the fewer parts that can statistically "go wrong"

Also very environmentally unfriendly. Shame on you, Philips!

From what I can tell, the non-USB OneBlades charge at 4.3V, not 5V.

It's probably a small enough difference that a 5V charger would work fine for the 4.3V shaver, but it wouldn't work the other way around.

Any change in the dc input/amps? Because that’s the only reason I would give any credence to it.

Please update the post with the facts from the data sheet OP

Remington also have different plugs for different models.

After realizing both shavers and cordless toothbrush chargers are going this route, I gave in and installed these in the bathroom

I saw a phone company make a trimmer, they used to do the same but now they are using USB c

I have the cheapest Philips shaver. It is pretty mid. It came with its own charger. On the shaver's side it looks like a standard ungrounded 220V female connection. But it actually is some propriety DC thingy. Very annoying. Why not just use USB-C?

Yep. It's not too easy to find usb-c shavers yet though :/

My travel trimmer takes a AA battery and I just keep a little USB charger for that.
