Can I safely use a portable jump starter on my Rav4 Prime? If so, anything special I should look for or look out for?
Do portable jump starters work on Rav4 Primes?

Not sure if the Primes engine bay is similar to the hybrid but if so, do not connect the negative clamp anywhere near the ECU. The issue with most jump packs is the cables are too short to reach the factory ground point on the passenger side of the engine.
Also, note that the positive jump point blade is metal on one side, plastic on the other. Some jump packs only have power on the wire side of the positive clamp, meaning the wire side needs to be connected to the metal blade side of the jump port.
One way, although more difficult, to mitigate both issues mentioned is to use the manual hatch release inside the car and jump directly to the battery.

your hybrid requires small trickle of current to power electronics and lights only. your traction battery will provide the power to spin the engine. I had a jump starter that would not provide trickle current meaning in order to activate it was looking for a huge current draw to spin the engine. fortunately a friend had 'type s' jump starter from Costco that worked and I carry it with me since then.
as in, access the battery terminals in the trunk? I haven't looked carefully at that setup, can they be clamped onto?
what is type S? google isn't readily helping me out here.
Yes, I plan on connecting directly to the battery in the trunk to avoid ECU damage. The battery is small so I see no reason why the clamps on most jump packs would not work. Certainly worth a trial run though.
yeah, I'm just wondering about how accessible the terminals are and if there will be any obstructions. I haven't removed the panels to look at the battery back there to confirm exactly what it looks like.
You may want to check the water level (add distilled water if needed) of the battery and grease the terminals while you are there. I believe all primes and J Vinn Hybrids have flooded batteries. My plan is to extend the life of the expensive 12 volt aux battery as much as possible.
flooded like they put too much water in the battery? I've never checked a battery water level. google says there is an indicator that "glows" on the top of the battery? how have I missed this all of my life???
So the battery in my Impreza has no indication of water level. It also indicates it's not serviceable. Is the prime battery serviceable?
No flooded meaning that it uses water and electrolytes which evaporate or something to that effect over time. Others can chime in with the technical answer but a "flooded" battery may need to be topped off over time with distilled water.
Some batteries are Maintenace free where no water can be added. Some types of batteries do not use water, they use other substances such as a gell.
Others will confirm but I think the Prime uses a flooded battery which is serviceable. Some state that it rarely needs water but still a good thing to check every once in a while. For me, in hot Florida, I check every year. I also check for corrosion while I am there and apply grease if needed.
Ah, thanks. If you happen to look please let us know 🍻

Right, but what does it mean in practical terms?
Interesting, I will need to try and measure my AntiGravity XP-10HD's current output and see what I can find out or email Antigravity.
@CoffeeBear I think @Eldorado19h is stating that some jump packs will not work on a Toyota 12 volt hybrid battery because there is not enough current draw demand from the car in order to activate the jump pack's output circuit?
For example, if one plugs in a small LED light bulb into a 15 Amp outlet, the LED bulb will draw about .05 Amp of current while on the same 15 amp maximum outlet (circuit), a 1000 watt light bulb will draw 8.6 Amps.
okay but does type S just refer to a current rating? what does it mean?
I believe S type is a brand of Jump Pack that worked for @Eldorado19h while another brand did not work.
At first glance, I suspect that either bad contact was made with the original jump pack or the positive clamp's wire side was connected to the plastic side of the jump port, but I have been wrong in the past. I just emailed my Jump Pack manufacturer for their take on this.
ah! when I saw it in the amazon listing I missed that it was the brand. I thought it was some kind of rating system for jump packs
could have really worked on me. "gotta get a type S or this won't work!"
They're the same.
And I can confirm that portable battery chargers work as expected. When I had the blown in-line fuse in the DC-to-DC assembly back in December and the Prime died on the road, I was able to use my portable charger connected to the battery in the trunk to keep the 12V system running long enough for me to get the car safely home. So that was an emergency situation but I'm assuming it would have worked in a normal "dead battery, charge it" situation too.
