Quad SATA kit power supply recommendations

#1

Hi All,

Trying out my version 1.1 sata hat and having a lot of fun with it, got it set up with 4 Crutial M4 SSDs which it seems to be able to handle pretty well. The only issue is that with the “high power” chargers i bought in preparation, including one with QC and PD, i am seeing that the power light on the Pi flickers and goes out alot of the time and when i check i can see it is throwing undervoltage warnings. at the moment i have found running a second usb c to deliver power to the pi (in addition to the usb c powering the hat) works around this issue but means i cant run it with the case screwed on (without drilling a new hole). i also see some issues when i start up the pi with just the hat supply plugged in where it struggles to recognise the disks until the pi supply is attached and the service is restarted.

Has anyone got any tried and tested charger suggestions that can do the whole thing with just the hat input? bonus points for UK amazon links!

Can you tell me the model and power of your power supply?

So i have tried with 2 chargers:
Currently it boots but undervolts when i use this Anker 60W charger
USB C Wall Charger, Anker Premium 60W 5-Port Desktop Charger with One 30W Power Delivery Port for MacBook Air 2018, iPad Pro 2018, and 4 PowerIQ Ports https://www.amazon.co.uk/dp/B072K5SFHG/ref=cm_sw_r_cp_apap_fzxnmxg7BQQhr

I also bought this charger to power it (as it advertises 40W) but found that the disk lights kept flickering in and out and the hat wasnt able to recognise them:
Official Huawei SuperCharge USB-C… https://www.amazon.co.uk/dp/B07MCY64JD?ref=ppx_pop_mob_ap_share

So i am currently running the whole setup using 2 usb cables coming from the anker power supply, one for the hat and one for the pi

Doesn’t your kit include a charger?

The so-called SuperCharge of Huawei may not be supported, it adopts its own charging protocol.

30W should be enough. But the conversion from 20V to 5V is very inefficient.

Choose regular PD or QC charger with power over 18W, preferably including 9V3A or 12V3A.

I thought Anker only had 20V*1.5A, but it seems that there are also 15V*2A and 9V*3A. It may be that the automatic selection of 20V*1.5A leads to low conversion efficiency.

I will search the box for a charger, i didn’t see one first time round but worth a shot

And in case i dont find one i was looking at this as a potential alternative:
PuiZhak Universal PD Quick Charge 65W 45W USB-C Charger With 1.8M Cable Compatible FOR Acer Swift 7, Spin 7, Switch Alpha 12, Aspire R13, Lenovo ThinkPad X1 Carbon, Yoga 920 720 & All USB-C Devices https://www.amazon.co.uk/dp/B07HMQ4HH3/ref=cm_sw_r_cp_apa_i_ptUrEbS75PXBC

It looks good. I also tried to find you a charger, but I didn’t find anything we tested on it.

Ill test it and report back!

Also cheers for looking
