The first power bank looks really nice, but I will take it a bit easy with ordering more stuff for review. I already have a lot of items on the way and in queue.
These power banks are definitely on the expensive side, I must admit I would like one. I am not going to buy one this month and probably not next month either, I have way to much “junk” in queue and I have used a bit much money recently (Bench DMM’s and other test equipment are not cheap).
But when my current queue is running low I may return to that list again and maybe order one of them.
That looks exactly like the Prufen Smart Cable from last year’s KickStarter project. There is a slightly updated version of it with auto-timer off (I think that’s the main difference of the revised version released this year). I think it’s available only in Singapore or ordered online from there (I believe the creator is a Singaporean).
I have that item. It’s not a QC2.0/3.0 converter, I think they term it as “QC2.0/3.0 trigger”.
If connected to a USB charger/adapter that only outputs 5v, then placing the trigger between the USB meter, it will only register the same 5v.
It only “triggers” QC2 or QC3 modes if the charger/adapter supports QC2/3. I tried it on a Mi PLM05ZM (Mi 20000mAh v2 power bank) and also a TronSmart W3PTA (so far those are my current chargers that support QC2/3). The left button on the picture changes between QC2 (5-9-12v) and QC3 (5-20v continuous?) mode. While the middle and right button is for “up” and “down” (if QC2, that triggers 5v -> 9v -> 12v; if QC3, I think it steps the voltage up/down). Since I only have 12v QuickCharge support for my 2 QC chargers, I haven’t tested the trigger for 20v (QC3 has 20v, but very few support it at the moment).
I saw a video by Mr. DodgeReviews of a QC2/3 converter which seems to actually convert the voltage from 5v to 9v to 12v (even when used with a regular USB charger that outputs only 5v), but it’s another item…
I think he means my (very eary) vid on the Juwei J7-I, same thing that HKJ has reviewed.

About €50 in ebay including shipping, no match on google shopping.

Way too high a price for such limited functionality.
I could spend that kind of money on a YZXStudio or ZKEtech meter that offers a lot more for the money, but not on this.
The Prufen Smart Cable (my guess is it was licensed to “intos.de” above) price as indicated here: http://prufen.com/shop/ is US$19.90 + $6.90 shipping (flat rate for most countries I think).
