Exactly! Shameless plug: we do a repairable design for e-bike battery which uses no glue ( https://gouach.com )

Not bad, I thought the folding prongs on this Apple adapter made it a fairly shameless plug itself :)

haha :)

Hopefully Apple releases a UK version of this adapter soon. The design looks very similar to my beloved Apple UK 20W charger [1]. I’d buy a 40-60W version in a heartbeat! [1] https://www.amazon.co.uk/Apple-20W-USB-C-Power-Adapter/dp/B0...

Don’t buy Apple products from Amazon. Especially power or cables. The counterfeiting is out of control, and they have no plans to fix it

They are getting rid of comingling which should reduce some of the counterfeiting problems: https://www.geekwire.com/2025/after-years-of-backlash-amazon...

Really nice, and in the future those cells could be upcycled or repaired. The design is also quite dense. To be clear, I have designed high-density electronics myself which were repairable - it's tough but doable.

Exactly! It's known that recycling pristine cells that haven't been glued/welded etc makes it much easier and efficient to recover lithium, so that's also a win for recycling

Please do not save money by using unlisted electrical equipment. Spend the extra $20 for a product that is tested and listed by UL/CE/ETL, it’s not worth burning a building down over $20. You couldn’t pay me enough money to plug this into a building’s electrical distribution system, it’s drawing ~3A at 120V (60W at 5V plus inefficiency) and in a very small form factor, I sure hope the engineering and QA of that $5 ch…

OP is in the UK where every circuit has a GFCI, making it pretty much impossible to get an electrical shock due to isolation failure (in a typical year, not a single person dies from electrocution in UK homes). Fire is more of a concern, but this is indeed internally fused and the IC has both overcurrent and overheat protection - both of which are effectively 'free', so there are no cost savings to not include them.

Gotcha, there are still locations where non-GFCI receptacles are allowed in residential homes in the US, they’re required in basements, garages, exteriors, and within a certain distance of a sink/plumbing tap but not in bedrooms or general ‘living space’. AFCIs are required in most areas but don’t protect against ground faults, which aren’t as concerning with a device that is injection molded plastic anyways.

The triple built-in protections alleviate the rest of my concerns, my apologies for overreacting but I’ve seen people plug some scary things into receptacles.

This is very cool, I might actually get one to charge my laptop. That being said... I can't be the only person who consciously avoids fast-charging my phone. My whole apartment is full of wireless charging pads intentionally plugged into weak chargers (wireless charging avoids putting wear on the USB port). 60 watts can't possibly be healthy for a battery small enough to fit into a phone.

Wireless charging is undoing all the gains of low charging speed because it's so much higher temp.

My phone doesn't get hot at all with wireless charging using a low watt power source though.

Also I am using magsafe which due to the magnet alignment leads to a high efficiency transfer at least.

I wish they'd discount their 35W dual port chargers or that I could find a similar 3rd party charger. My main criteria are (1) dual USB-C ports to charge multiple devices in one location, (2) compact enough to not block the other receptacle, and (3) ports face down/to the side so can fit between the wall and furniture. Unfortunately most chargers fail at least one of these.

Depending on your location and exact geometry needs the IKEA SJÖSS might do it.

The IKEA SJÖSS has ports on the front face rather than down or side.

Why wearing out more? I’d been planning on pulling out an old charger to slow charge overnight.

I suppose the previous comment was likely saying more compared to not charging overnight, and fast charging in the morning. I would also have guessed the slow charging was better, but that is an uninformed opinion. I'd be quite interested in what people think. An extra dilemma - often if I'm around the house or the office all day, I'll just plug in my phone every time I see it reach about 70%, and unplug when it reac…

To be clear, I also don’t think it really matters. :)

That said, my assumption is that most people want to charge overnight precisely because they do not want to have to remember to do a fast charge in the morning. Maybe that’s just me tho. Assuming you want to charge overnight, I totally agree that spending less time between 80% and 100% is good, and software that either prevents this or limits it is good. But whether you have such a device or not, for overnight charging a lower power charger seems prudent.

This isn't exactly what you're looking for, but it may fit the use case. I've recently been replacing some of the wiring in my house as part of a renovation, and I discovered that Leviton sells outlets with PD USB-C built in now! Not talking about the useless 2A USB-A "built-in" chargers of yore, now they actually have proper PD up to 60W! They do also sell non-PD, so it requires some careful checking of the model nu…

This is good to know!

I might use these in my basement remodel since I can easily install deeper boxes. A right angle connector cable would also solve the issue of the port direction.

Regarding ChargerLAB's products: I have an HP Zbook G1a laptop that uses 140W USB PD charging. However, except for the HP charger, I have not found a charger or cable pair that works. After a while they start cycling charging on and off. Under heavy load that happens almost immediately. Under light loads it might take hours. Is there a ChargerLAB product that can explain what exactly is going on between the computer…

I have this laptop and this is so frustrating. I am hoping that they can fix this with a firmware update.

They’re doing a handshake with the adapter to see it’s not an HP charger, Dell does this too on its docks

I don't think that's it because I have seen some reports of this behavior online with the official charger.
