Title: Power bank circuit that let the magic smoke out
Post by: Danielradcliff on March 27, 2021, 03:02:30 am

This power bank circuit was working fine until all of a sudden It irrupt it in sparks and fire  and smoke
This power bank circuit board is from Amazon in the US I’m Sending it back to Amazon to get a new  power bank circuit board  hopefully This is a one time occurrence. Here’s a link to the power bank circuit board on Amazon see what you think about it everyone do you think it Technology doggy or decent  https://www.amazon.com/dp/B08MXM75V1/ref=cm_sw_em_r_mt_dp_EAWAAV71F287ND39RG14?_encoding=UTF8&psc=1 (https://www.amazon.com/dp/B08MXM75V1/ref=cm_sw_em_r_mt_dp_EAWAAV71F287ND39RG14?_encoding=UTF8&psc=1)

There's a datasheet for the SW6106 PMIC that let the magic smoke out here: https://www.waveshare.com/w/upload/e/ed/SW6106_Datasheet_Release_DS008_v1.0.pdf (https://www.waveshare.com/w/upload/e/ed/SW6106_Datasheet_Release_DS008_v1.0.pdf)

You can check if component values match the reference design and if your usage was pushing it too close to its rated limits.

Note:
When Using More Than 2 Output Ports at the Same Time, The Fast Charge is Triggered By Mistake, All are 5V Output

Not sure what they mean by "triggered by mistake" whether all the outputs are limited to 5v when more than one port is drawing power.
