I have carried my Slime pump for fifteen years on long distance rides. I decided to try it For the first time last week and it doesn’t go!Carried my Slime pump for years without having to use it, then when I needed it the internal wires were broken, they were left free to flap around and soldered copper wires don't like that.
Replaced it with a budget priced Coleman , internal wires either tied or bedded in silicone so no flapping. Worth checking on any pump purchase!
Works fine, came with the same connector as the pigtails for my battery charger so easy to use without any dismantling ,
I have had a Noco Genius power pack for about five years, still works perfectly and it is part of my everyday tool kit,
Will start everything it has been connected to , and has provisions for USB charging too.
I run HD tubes , last two nail punctures I had could be fixed with a pressure pack sealant, some specifically mention tubed tires on the can.
Don't get many punctures, quality tires , ditto HD tubes keep the pressure up and replace them at 80% worn and you will avoid most.
And don't ride anywhere near the county dump either, if you can avoid it!
I found this excellent for exactly the same reasons except the battery never needs charging or goes flat..except if mine is.
