I have looked at the two RD meters:

Interesting charger.
Can you test the new GaN charger from Anker? Supports PD up to 30W and itâs minuscule.

There are alternatives from Ravpower and Aukey to new GaN chargers, too.
Oh my :facepalm: God! I recently assembled two of these power banks (with cells soldered) and just noticed the circuit comes stock configured for 4.35V cells! 
I have a spare circuit board lying around, measured 4.33V open circuit voltage, confirmed. 
Just adviced my two owner friends of this issue, gonna have to carefully open those boxes. They've run just one cycle to 4.35V and they're built with resilient 35E cells, fortunately.
Who's the #@%@$ who decided such stock output voltage configuration? The majority of 18650 cells in the market are 4.2Vmax cells, even if we only take into account energy cells.

So you can donate some predefined amounts to the projects in the above page to get the product with a more or less equivalent discount. Example: $89 contribution to get the product at 40% of the $149 retail price ($148,60 total). The $99 contribution gets you a worse deal (34% of retail price or $149,66).
It's sooo cheap!

Looks good on paper. 
I have searched this forum for FLOVEME Chargers, seems none of them have been tested yet. Looks good on paper, very economical, and Iâve only gotten one USB cable from them and it seems decent quality. But I donât have the testing expertise or equipment you do!
Am curious how well this will test.
Seems to be made by JIAYU ELECTRONICS. No reviews found anywhere online on this manufacturer.
I have ordered one.
I came across this on EBay and wondered if people here might be interested:
Itâs a Li-Ion to USB booster board thatâs supposed to have QC2.0 / QC3.0 built in. Might have potential for DIY powerbank projects in conjunction with a TP4056 board and a decent cell or twoâŚ
Iâve ordered a sample, but I donât have the equipment for an HKJ-grade review. Iâm basically going to plug a QC2.0 / QC3.0 trigger board into it along with a variable load module and see if the magic smoke comes out while I monitor it with a multimeter 
Works fine up to 4,5V.
Maybe I shouldâve done a review for itâŚ
Thanks, just knowing that it works is already helpful 
I bought a ZMI (supposedly the OEM for Xiaomi) 65W HA832 charger that is working well for me to charge both my Lenovo Yoga at 45W and my iPhone but am curious as to how it works under test conditions.
I will ask Nitecore about it.

No need to test the 4th one.
Already have it, tested its capacity, its protocols, etc.
Want to know anything about it?
