Ecoflow Alternator Charger

[Boyink]

I have an Ecoflow Delta 2 that we've been using for a while now. I recently scored a deal on an Ecoflow Alternator Charger (Ecoflow's DC-DC charger).

I searched here and didn't find much about these - is anyone using one? It'll be a little bit until I'll be installing it - but overall just wondering if I should also upgrade the alternator (assuming a 105A stocker on my Chevy Suburban).

You want to keep total amps, alternator load, below 60% or so. So 62A on yours.
I have extensively tested my Tacoma with all loads added one by one and alone.
Engine uses 8.3A idle, 10A at 2000 rpm driving.
Hibeams, wipers, full air-conditioning, turn signal, gives 42A.
Power brakes adds 10A for 10 sec or so, then 4A for brakelights alone.

So in bad weather, night, you have 20A to use, maybe 25A. So 270 to 330W.

In day good weather, your car will be about 20A if you turn off unneeded loads like daytime headlights. Then you can get 40A at 13.5v or so, about 500W, from your alternator.

Don't try to get or expect 800W, that is bogus Ecoflow marketing. You can run it fine at lower settings. Get a bigger alternator if available... none is for my Toyota, 130A max with tow package.

Cool, thanks. Yea - lots of alternator upgrade options for the Chevy V8s. Sweet spot seems to be ~ 240A for around $300. Can get more (A) for more ($) but not sure I'd really need it.

Nice thing about the Suburban is that the alternator swap is a 10 minute job (at least it was on my 1500.) I think I only needed one tool (13mm? socket.) I'm pretty fumble-fingered so if I can do that swap in 15 minutes, literally anybody can.

I have read that some of the higher-amp alternators use a differently-sized pulley, so a different serpentine belt is required as well.
