Their photos all seem to be hiding the connector between the unit and the power tip. Is that standard or proprietary?
I assume it's proprietary (are there even standards for this kind of connector?). The charger body has two fixed pins inside a circular collar with two tabs on it that the tip is placed over then rotated 45 degrees to lock.

Gosh that's odd; Ravpower has a blog post about UL certification's importance ( https://blog.ravpower.com/2018/04/usb-charger-safety-certifi... ) but you're right, their RP-PC104 45W GaN USB-C wall charger and its manual don't list UL certification information ( https://cdn.shopify.com/s/files/1/0257/5656/5579/files/RP-PC... , https://www.ravpower.com/products/rp-pc104-45w-pd-wall-charg... ).
Re: The next generation of wall chargers
#143There's a pretty good site, https://www.chargerlab.com/ (see also: https://twitter.com/chargerlab ) that's dedicated to reviewing charging peripherals.
I started off the year with an Innergie 60C, which has worked great for everything I've thrown at it and is tiny (55mL volume, 88g, 60W USB-C PD). It was on-sale recently, but even at full price has been worth it for me. (Although the newer RavPower PD Pioneer 61W is a good alternative that's almost as small and 1/3 the price.)
I'm looking forward to adding the upcoming Sanho HyperJuice 100W charger (about twice the size, but a bunch more ports) https://www.kickstarter.com/projects/hypershop/hyperjuice-wo...
Instead of the Anker PD1 18W, for a small charger, I use the Anker PIQ 30W - it's very slim, which actually makes it much easier to carry around. Also, the IMO folding plugs (and extra juice) are definitely worth the extra volume.
Recently, for my Mavic Pro 2, I just got a cheap Cablcc USB-C to Plug Receptacle Charger cable and a RCGEEK car charger that seems to work well as a nice 2-in-1 (it only saves a tiny bit of volume and weight over the wall charging but it also provides car charging).
Also, although I'm unsure of how often I'll need it, I got a 100Wh Zendure Super Tank power bank (which provides USB-C PD 100W charging), since it was discounted heavily for Black Friday (it was only $100 on sale vs $200+ for other similar options).
Also, I travel internationally a lot, and the MOGICS Donut has been my go-to combination power strip and adapter - it's the best/most compact device I've found (and has 2 USB-A chargers built in to handly legacy devices). https://www.mogics.com/3824-2

#145I'm still shocked at how poorly most plugs are designed for fitting in various outlets and power strips.
that's mostly because American domestic outlets are the worst in the world.

I have the RAVPower 61W GaN USB-C charger for my backpack. No UL, but no noise and no issues. It's currently five stars on Amazon, for whatever that's worth. https://www.amazon.com/dp/B07TC53ZYD/

I’ve had the slim 45W RavPower one since June and it’s great. It’s almost startling how small it is. I much prefer it in the bag for coffee shop trips, etc. I use it with my 15” MBP and I haven’t seen any power issues with plenty of Chrome tabs and InDesign/Photoshop running. I usually have the extension cord on the 87W one at home—it’s so nice not to have to lug that whole assembly or look for the smaller attachment…

I saw someone do this with the plug to a laser printer once. The toner literally exploded in his face when he plugged it in.
That’s why you check that the printer can even support 240V before you do this
