These devices generally work to augment a battery that just doesnt have enough umph to start by itself. In some cases, you even need to sit these on the battery for a while to transfer some charge so they can help. I would think you would need a pretty small engine (tractor/etc) to start it solo without a battery. While I can’t say from experience, I would think starting a car would be difficult to impossible solo. YMMV
Plus, you need a Pb-acid battery to essentially regulate the system voltage that the car sees. A different chemistry battery can have too high a voltage andd fry the electronics, and running off the alternator alone is generally a Bad Idea.
Exactly. The one I linked has a SLA high-drain battery. It’s a whole lot heavier that the lithium units. Like everything, it all depends on how you plan to use it.
Maybe not the greatest, but will certainly work in emergency.
What I’d really like to know is if this GooLoo could jump start the 6.4 V8 engine in my car, but short of severely discharging the battery in the car (which I don’t want to do), I don’t know how I could test that.
When the car’s battery died last year (I think it had a bad cell), I could not get the car jump started by hooking up jumper cables to my other car. Finally a guy with a flatbed showed up, and he had a jump starter similar to that Clore one linked above. It started the engine right up.
You could disconnect both battery cable, and connect jumper starter directly to car, think you may have to push boost button if it has one, some starters wont work unless there is some power in the flattened battery.
Wowtac A5 Flashlight in both Natural White and Cool White available with 20% off coupon gets you a 26650 Flashlight that hold 1800 lumens for 90 minutes for $39.96 ( at least according to ZeroAir reviews).
I think the most recent summary is this: AmazonBasics appears to have changed their supplier over the years (some now made in China) so it’s hit or miss while Eneloop is consistently good (albeit expensive). YMMV
The only lights I have that use AAA are a doxen the $1.00 ones from Walmart with 9 LEDs and 2 obtained in Korea with 27 LEDS that all use 3 x AAA..In all these cheapies I put Kirkland alkalines from Costco(64 pack).
My BT mice and a couple of remotes employ AAA that also get fed alkalines.
I have 7 lights that use AA and 3 of those take 4 each.They get fed Envelope Pro,Sanyo XX or white Eneplops
