Trying to fix a flat or adjust the air pressure on fat bike tires with your standard hand pump is a tedious endeavor. Instead, use Lezyne's fat-bike specific Micro Floor Drive XL that maxes out at 35 PSI but pushes a much larger volume of air than standard hand pumps. Lezyne's Micro Floor Drive pumps are a godsend to many mountain and road bike riders as their integrated flexible hoses and flip-down foot pegs make for an extremely stable and ergonomic inflation position. The XL includes a thread-on chuck with an ABS air bleed valve and a CNC-machined aluminum barrel for light weight and excellent durability.
35 PSI max pressure. Compatible with Presta and Schrader valves. 303 mm length. 367 g claimed weight.

Easy to use and moves almost as much air volume as a floor pump but still fits easily into my hydration pack. Thread on head means you don't have to worry about breaking the valve on the tire and you can inflate a 29x2.35 in about 20 strokes. This pump is made for the new plus and fat tires but also works great on standard MTB tires.
This little thing makes quick work of pumping up fat bike tires. The threaded chuck locks on securely and the high volume gets me from 2 psi to 10 psi in no time. The only negative I can think of is the foot peg doesn't do much. Oh well. Would buy again.
After trying several mni pumps requiring 5-10 minutes to minimum inflation I got this pump. 20 pumps took 29x2.35 from 20 to 30 psi. Not light, but only a few ozs. more than 2 16 gram cartridges and inflator. Works great to 35 psi. even for fat bike tires. Unlucky, get second flat and cartridges spent, pump still ready. Even better than low volume frame pump.
