Flashlights I've encountered (EDC size, single-18650) with genuine XM-L2 and micro-USB rechargeable port, include:
1) Convoy S9 = XM-L2, micro-USB (1.4A ~ 500+ lumens), several tints available
2) Eagle Eye X2R = XM-L2, micro-USB (1.6-2.1A ~ 550-760 lumens), cool-white & neutral-white available
(seems like the old batch had max 550 lumens while newer batch has now upgraded to 670 or 760 lumens -- differing documentations from different sources)
(the EE X2R looks almost exactly like a Convoy S2+ with the addition of a micro-USB port)
3) On The Road U18 = XM-L2, micro-USB (2.6A ~ 900? lumens), available in cool-white and warm-white tints
(*added note: it seems like for the OTR U18, the cool-white version uses XP-L V6, whereas the warm-white version uses XM-L2 U3-5C)
(bonus note: The EE X2R uses a No PWM driver, the Convoy S9 driver has PWM, the OTR U18 supposedly also has No PWM)
There are other lights with micro-USB charge ports, but these may be a bit longer in size:
4) Sofirn SP30A (XP-L HD, 1000 lumens), this flashlight is longer than other EDC-size
5) ZanFlare F1 (XP-L HD, 1240 lumens) = available in cool-white & neutral-white
6) Wuben L50 (XP-L2, 1200 lumens) = (very) cool-white
7) Fitorch P20R (XP-L HD, 1000 lumens) [the documentation indicates XP-L2, but actual LED is XP-L HD) = cool-white
Of course there are others, but those are what I've checked out (reviews, etc)
