What type of (car) charger should I buy?

[Robert]

I don't see any chargers for sale advertising compatibility with Pump Express. They are all either QC or USB-PD. Are either or both of these compatible with Pump Express? Do I just have to match volts and amps? How do I know if the Cosmo can negotiate the volts and amps it wants with the charger?

So my question is, ewhat type of charger should I buy (yes, I can use the stock charger, but I also want a car charger, and probably a multiport-charger....)? This is my first device with USB>2 charging, so I haven't had to learn about this yet, and what I read is confusing.

Thanks!

Since you already asked the same thing in another thread, I replied to that there: www.oesf.org/index.php?act=findpost&pid=293588. Basically, as Pump Express + is as common as hens teeth, and not compatible with either QC or USB-PD, any 5V ~2A USB charger of reasonable quality is the next best.

Thanks very much for the detailed answer at that link.  (I posted a new topic because I was afraid the question would be regarded as off-topic in that other thread.  If that was a breach of forum etiquette, I apologize.)
