CES 2018: myCharge Debuts 20,000mAh 'All Powerful' Battery Pack That Can Charge Anything

If this had an Apple Watch charger built-in, I'd buy it. I hate having to lug around that cable separately, but I don't want to have to carry multiple battery packs either.

Same boat, I gave up and ditched my 20,000mAh charger for a 5,000mAh battery with apple watch built in. I'm constantly worried about running out of power at an inconvenient time though.

I really think there's a market for a high-capacity battery with built in Apple Watch charging. The highest I've seen is the Belkin with 6700mAh which is overpriced and has bad reviews.

mAh… this unit doesn’t say anything about the capacity. At what voltage? 0.00001mv?

The standard for these is to quote the mAh of the actually battery, which is around 3.6V, and not the output from the ports. so you're looking at 72wh before losses (I'd expect closer to 50)

Of course the manufacturers want to quote nice big numbers, but a lot of people are being mislead because of the voltage issue and because the transfer efficiency is conveniently ignored.

This and screen diagonal. They take a screen, stretch it to make it wider (than it should be) but the same area, and now its diagonal is larger.
 
Haven’t seen anyone mention the real problem. I had one of their current units and it won’t effectively charge a MacBook Pro even though they mention laptops. The USB-C to USB-C cable will sort of give it some juice but it will trickle to death of the laptop is actually being used. When I tried the AC plug with the brick, it would error out. The power bank only does 65w and the Pro needs more :(. This makes it a lot less useful as a laptop charger.
 
Why not put a USB-C PD port on the myCharge Unplugged 8K and make it the best of both worlds? Then I could charge its battery more quickly, fast-charge my device when I need it ASAP, or lay it on top for wireless charging when I have plenty of time?
 
Oh my if any of these explode or burn it's going to be a BIG/dangerous mess. I don't really need one so I personally don't need to worry.

Why in the heck don't they rate these things in watt-hours, which is actually a useful measure of stored energy?

mAh doesn't mean anything without knowing the voltage of the internal battery.

That’s exactly why. Walk around your local Walmart sometime and check out the power packs. They are cheap enough, $10, $15, $20, but NONE of them deliver the capacity that is advertised. They just don’t. It should be illegal and they should be put out of business, but that’s just the way it is. Don’t even think of buying a tiny power pack, it’ll charge an iPhone about 35-40% even though it claims to charge your phone “2x!!!!”

Agreed it should be illegal. Quoting Watt-hours would be a step in the right direction but the problem is also that they quote the nominal energy capacity of the pack, NOT how much of that energy is actually transferable to another device.

Transfer efficiency is as low as 60% on some of these things. It is like buying a pint bottle of milk and pouring it into a glass but finding there is only a bit over half a pint in the glass.

It would be illegal to sell pint bottles that only contained 60% of a pint.

Wow...That big myCharge would look SOOOO much better and elegant on my desk than a tiny little Lightning cable! What an advancement into removing the 3/10th of a second it takes me to plug into my phone! What an amazing time we live in!! So glad we have reached this level of tech in my lifetime!
