Bontager's flash charger is a unique pump and compressor aimed at tubeless tyre users but its combined design is its weakness as well as its strength.
On the plus side, the big tank contains enough air to pop every tubeless or tubeless-ready tyre and rim combo we’ve tried into place as soon as we’ve thrown the big red pressure-dump switch. Even if it hasn’t inflated it fully in one hit, a quick burst of pumping has sealed the deal. While it’s the same price as a budget electric compressor, you can use it at trailheads, in race pits or anywhere else, and though it’s heavy and bulky compared to a conventional pump, the one-piece construction makes it relatively simple to transport.
The low-volume stroke means it takes ages to get the tank up to pressure though. Because there’s no way of separating the pump and tank, if you accidentally discharge the tank by leaving the dump valve open when you release the valve head, you have to recharge the whole system again – even if you just want to top up an already inflated tyre. The plastic hose, head and attachments are disappointing for 150$ too, and more vulnerable to accidental damage than metal fixtures. While spares are available, the combo design means that if there’s a problem with the pump the compressor tank is useless, and vice versa.
A smart idea for tubeless tyre users, but we expect better durability and build quality for 150$
