What kind of charger or what is this unit actually?
« on: October 19, 2019, 07:12:54 pm »
Hi!
I found this device on the net
https://powermaxconverters.com/product/pmbc-12-volt/

cos I wish to have a heavy duty car electric power supply to have a stable
power source to the car until programming the car ecu's.

My question is:
1. is this actually a regular battery charger with more power then a standard one?
2. it says it can continuously handel 100A (some model, other 55A etc.), what that means?
For me that means does I can connect 1.4KW over several hours to the unit, through that thin sheet metal clamps on the picture.
From my perspective that is not possible with that clamps and maybe the cables are also a weak point.
3. can this unit actually delivery high current, lets say 100A for a small amount of time like in some
situation where are peak voltages and currents are reached? Or what?

What you say about the description of the units on the link and a real world situation with this unit?

Thanks.

Just an overpriced power supply. If you want something on a budget and are willing to do a bit of hacking, mod some ATX PSUs.


You can also look at inverter/charger units of the kind used for RVs and other small off grid systems.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

There are some warning signs for this product:
1.  No certifications listed
2.  Warning not to leave this device connected and unattended.
3. Made in China sticker; not that made in China by itself indicates poor quality, but added to the above items it should be another warning that this may not be the device you want to trust fully.

At least they have a real address and real phone numbers; call them up and ask to speak with an engineer and see what develops.  Ask what the certifications are and why they don’t have it UL listed.  If all you get is marketing talk and no substance, just skip over this one.

My personal favorite battery chargers are the Blue Sea Systems marine certified for use in boats.
