It is is my truck right now but no, I never did get around to using it as a charger or anything. Quite happy with the purchase however - I detect alone in some places where the peace of mind is worth every penny.

I had other sources to charge from and never got around to it. I would not buy it just for that - as phrunt noted it is designed to do lots of starts, but not so much for charging capability. That’s like a bonus feature for me.

Still showing 100% charge after 8 months though I am sure it can use a little topping off.

Just a caution,  a battery that has lost a lot of its capacity can still show 100% charge regardless of its chemistry. The battery indicators are voltage based, a sure way to test is to load the batteries up ie. start a vehicle with a flat battery. Just a warning, nothing worse then finding it is so in an emergency. This is why with our old tech wet lead acid batteries a SG of the electrolyte is recommended over no load voltage reading, unfortunately I know of no way of testing a lithium battery except under load and doubt there is a method.

I always have a 1k watt genny, battery charger, and an extension cord with me even if more than two vehicles are with me. There has been a time or two both vehicle's have let the batteries get too low and a portable battery pack just doesn't have the guts to get a diesel going when it's cold out. 

I'm more worried about things like in the picture. I was fortunate to have another truck there, but I would have been just fine riding 50 miles into town and back on a four wheeler for parts in early January in N. Nevada with highs around 30° . Be prepared if you are a ways out and be able to save yourself, help may or may not come in time.

Good yarn Jim. Thanks for telling. Was well worth it.?Gotta love jet boats. Did you ever consider running your dredge off the jet boat pump unit? Been done here in NZ. Purpose built jet boat & dredge all in one. Cheers

Good luck out there

I've seen that done JW, but I had no need, my five inch was quite adequate for what I was doing. Soon after this I sold the boat and built an airboat.

One point, if you have a Diesel engine, Genius has a jump started made just for them and for different  Diesel engine displacements that take in account engine size.

One other thing on the topic, a very inexpensive Solar panel from Battery Tender can help keep your batter/s charged during the daytime. I have one and it works very well.

Hey Steve I have one of those and also have 2 others called the Halo that I keep in a couple other vehicles-They all work great and you can get more than a few jumps before needing to be recharged.They are alot more compact than a car battery theyll fit in your glove box-Good choice for sure ? Mike C...?

I carry one around on my quad at all times, its saved me at least once when the quad gel cell battery was on the way out. I’ve  also used it to top up my phone in fringe areas where the phone battery dies really quickly and a couple of times have used the torch on it when I was out after dark.
