Anyone familiar with these? Any thoughts on safety?
Haven't use one of those. I am however familiar with a similar product.
The ones we have seen and used have a fusable link in the cables. This link is there to protect the batteries, and only seams to last a couple of jumps. Then you have to replace the cables.
Lithium batteries can be very dangerous. Also they do not like the cold.
Shorai batteries are a good example. The built in breaker can leave you stranded, or just simply a cold morning.
I think they are a great idea. The technology is just not quite there yet.
From the video, looks like this unit uses Lithium Iron Phosphate technology which is much safer than lithium polymer. Supposedly, no thermal run away problems. They do have reduced capacity when cold. I impulse bought a cheap one at Wally World a few days ago for $30, was $40 before Christmas. The NAPA one looks much nicer. It is 12000mah so, it should charge a cell phone 4 or 5 times.
Made for napa by schumacher same as there red fuel sl1 I had the sl1 that I kept in the bike and I let someone borrow it and haven't seen them or it since ,it doesn't have the inline fuseable link like some other jump starters in the extreme cold it wouldn't jump a bike unless you warmed it but would still charge my phone and laptop there are some reviews on amazon ,that's where mine came from
I'm looking at one of these for my trip this summer. I have too many devices to charge. Phone, iPod, heated grips and heated vest. Not to mention the new lights I'm installing. I'll put in a new battery before I leave(mine is over 4 yrs old) but I don't want to overload it.
Oops. Heated gear in July??? I may have divulged my destination 8)
Not sure what your heated gear pulls. But the bike should be able to run a good set of LED lights and charge devices with no problem.
BTW, I Bet I can guess where you be going.
