Samsung 30T
The Samsung 30Ts are the best 21700s for high-wattage vaping. While not the longest lasting of the bunch (quite the contrary), if you are in the market for powerful 21700s you should get some 30Ts. Up to recently the only cells that could reliably go up to 100 watts, 30Ts are also ideal for 21700-compatible mech mods.
