Cooked by USB-C charger?

So anyone ever had multiple devices cooked by a USBc charger?

I’m using a Hyperjuice charger with 3 USBc and one USB a and a 100w capacity. It is supposed to have both over voltage. Over current and all that stuff (this is the pass through version that you can plus another 120volt plug into)

I’ve used it for like a year without issue. I’m in Honduras on vacation and tonight I plugged my go pro charger into its USBc and nothing worked. Then I tried my iPad. Nothing. No charging indication but my USBc to lightning charger my ihpone just fine.

Then I tried my MBP 2018. Nothing. No charge. New cable. Nothing.

Troubleshoot. Use my power delivery external battery pack to try to charge the MBP. NOTHING!
iPad to battery pack. Nothing.

So it almost looks like this charger cooked my iPad AND my MBP?!? Should that even be possible? Not one of the USBC ports works now. Just dead to charge.
 
What about the battery pack to GoPro...does that work? Or GoPro to MBP or iPad...are you able to read the memory card? I feel like it could just be a bad cable since your USB-C to Lightning one is working, but what are the chances you have two bad USB-C to USB-C cables?
 
GoPro charger USB A to usb c cable via battery pack no go. Usb A to usb C cable number 2 to GoPro camera no go. So that’s 4 cables. Seems everything that touched this charger won’t charge.
 
If it's an M1 Mac try restarting in safe mode. Otherwise try resetting the SMC. And don't try that charger again but a different one.
 
Here is the amazing part, the HyperJuice cooked the USB-C multimeter I bought on the first plug in. Literally the multimeter worked fine on other chargers, plugged it into the HyperJuice and now the USB-C side of the multimeter won't work either.

 
Sorry to hear that. USB-C is far more riskier than previous generations because of the higher voltages. Just not worth testing a $50 charger using a $500 device. My rule is if the cable or charger fails, toss it.
 
Since even a nice USB-C multimeter won't read the voltage without blowing up I've ordered a USB-C break out cable to use a regular DC multimeter on. I SUSPECT line AC voltage is being output but can't be certain as of yet.....

Super unimpressed. I'm switching to 100% Anker or other high quality/longer in the business company. I'll post video/pictures of the multimeter readings from the break out cable when it comes Tuesday.

They directed my to their legal department where I assume I will be summarily shut down. I hope for them to be honest and fix the damage their device caused but I think the chance is near zero.

Honduras' average wall output is standard at 110V. As per USB-C Hubs, I would never recommend daisy chaining devices to a hub for charging purposes. It just opens the door for all kinds of hell.

I would stick to the one charger per large device rule and smaller to the traditional watch, phone & AirPods 3-in-1 solution.
 
Breakout cable showed the issue. Port 1 USB-C on the Hyperjuice stackable is pulsing DC voltages to over 60v. AKA Hyper is full of crap when they talk about over current and over voltage protection. Pretty sure they went cheap in their design given all the overheat failures and multiple reports of cooked devices on Reddit.

Overvoltage/Overcurrent means nothing in a catastrophic failure. I suspect ESD blew up the power supplies switching regulator or maybe some components (like capacitor, inductor) were under-rated and blew. Unfortunately it did not fail safe, sorry to hear that!
 
There was an article some time back about the risks of using cheap 3rd party chargers - lack of protection with sub par components. Sorry about your losses.
 
Oh no. I have the earlier 100 watt Hyperjuice. Even though it hasn't killed anything yet, I don't think I can trust it based on this thread and others on reddit. I suppose the pass-through could be the root cause which the earlier one I have doesn't have pass-through, but they probably cheaped out or underengineered it.

60V? They want to fry everything then...
