I've even started carrying a USB extension lead for the 50% of hotels where the closest power socket to the bed is somewhere across the hallway. Grrr!

Travel gadgets is a bit of a hobby of mine to be honest - I swear I have spent so much money on cables and chargers that I could have bought some new gadgets instead, but I just can't resist if there's something new that's 3-in-1, foldable, retractable etc. And it's really satisfying when I find something that works for me, out of five attempts or so that gather dust on a shelf somewhere!

I'm just glad I was able to permanently say goodbye to the beast of a Dell power brick for my old laptop from two generations ago, and can finally travel with just the Mu. That in itself must have saved me a few years of back pain...
Is that a 'Mu One' ???

I have a fair amount of experience with USB type C power delivery both as a consumer and a hardware product designer.

The short take is that USB Type C is a nightmare. The connectors, particularly the receptacles, are themselves terribly fragile both physically and electrically compared to USB A and even micro B. This means that the devices themselves become sacrificial rather than the cables, a much more expensive proposition.

Repairing the receptacles at component level is not easy because half the pads are hidden beneath the connector itself: you need the right skills and equipment to repair them. In the event of an electrical failure, youíre typically faced with a complete board replacement.

For the latest Apple MacBook, with a single receptacle for everything, thatís a £500 repair from your Apple Store. Replacement parts for a component level repair arenít available outside Apple except from donor boards. Keep in mind that the SSDs are soldered onto the board, so remember to scrub it before it goes for repair, they keep your old board and hand you back a wiped machine.

Furthermore, not all USB type C cables are made equal. They may look the same, some even may appear to be electrically the same if you buzz them out. But not all are suitable for Power Delivery, particularly at higher currents.

Most cables that support PD wonít support USB Super Speed, DisplayPort or Thunderbolt.

A PD cable that works at 35, 45 or 65W often wonít work at 85 or 100W: consumers must carefully check the item description before purchase.

Regarding PD chargers, itís not uncommon for a 45W charger to appear to work with a 65W laptop. However be aware that not only will charge time be slowed, it is likely that the machineís performance may be throttled as a result.

The attempt to make a universal standard is noble. Where USB Type C falls down is that much of the standard is optional, and consumers cannot be expected to understand the numerous nuances, or know the right questions to ask. I dread to think how many apparently suitable cables and chargers are purchased by unsuspecting purchasers, which turn out to be landfill and a frustrating user experience.
Stez, Flying Yazata and jerub like this.

Interesting

Presumably this makes something of a case for those magnetic connectors that can be bought, where a small gromit thing remains attached to the device and magnetically snaps onto the cable when presented to it.....

The depreciation of MagSafe on Apple laptops was a retrograde step in my view.

I agree. At what price progress?

It is indeed! I've been a fan of the Mu's for a while - I just hate the bulkiness of the UK power plug. Truth to be told I still end up lugging around travel adapters and sacks of cables, but it does fill me with great satisfaction when the UK plug collapses down

Seemingly hard to get hold of at present though....

I've been a long-term kickstarter backer so I think I got first dibs. Works exactly like advertised so worth keeping an eye out for if/when they do get into stock for general consumption.
