Just 27 grams including it's in built battery, up to 17 hours run time. I bought one for my Camino trip and it was perfect. So light and I could recharge it via USB. Actually all devices I took were USB rechargeable and none used disposable AA or AAAs. I was so happy, I ordered another when I got back. Nicely bright on full.
Yes more expensive than a 3 x AAA powered one from Anaconda but those are about 127g with batts. I was happy to pay more and save 100 grams from my kit. A bit like genuine nitecore tube lights cost a bit but are way better than the clones. I have seen similar looking units to the FH100 but the specs are nowhere near as good. This is light (pardon the pun) and brilliant. Oh yes and I'm not affiliated in any way with xiaomi or beebest - just like I'm not affiliated with naturehike. Just love great camping gear I can get for cheap from China. Catch have them for $44.91
