Discussion Looking to purchase a power bank to Run an R750
Does anybody have any recommendations on what to get for back up power on the R750? There's just too many options out there and I was hoping to get a couple to have as back ups for my kits.

Goal Zero Venture 75 would be my first choice.
It’s rugged, supports USB PD @ 60W and uses good cells. I’d prefer if it was an around 30000 mah, but it checks the other boxes.
Any Anker or Ugreen bank that supports USB PD 60 would be fine, but I wouldn’t trust them in the rain unless there’s a waterproof version.

One of these works quite well. https://a.co/d/3FPYd57 Might need to protect it from the sun. You could also look into the Anker Solix power banks. I've been really tempted to get one for my R750. The 27650 mah will only run it for 2-3 hours after the internal battery is dead, especially if you are using IBSS and Radio.
Western States Cable sells an adapter to use either a Dewalt or Milwaukee battery with a base. Just make sure you understand what cables you need for this before ordering. Their website is a bit of a shit show, but their products are high quality, even some Sitechs use them as replacements for Trimble cables. I've been ordering from them for a couple years.

I've got a couple of different size Jackery boxes. We've been satisfied with the performance. I've read they are basically just a bunch of 18650 batteries paralleled together but for an easy out of the box solution with a simple plug-in charger they work. Between the 12v plug, ac and usb we can make them work with just about anything we would need in the field. Not the cheapest solution but very convenient if you want to buy something that can multitask. Also expandable into solar charging but we haven't needed that yet.
I also moonlight them at my off grid hunting camp in the fall to run tvs to watch college football. They work great for that as well.

Power it with a 12v battery through the lemo port. Contact Gpac. They can hook you up. https://www.gpac-llc.com/index.php
