I am glad it works with my PD Battery packs. I’m glad the batteries seem identical in performance to the BLX-1 OEM units. I will order a second set as well. I can charge batteries from a port in my car while traveling, or from my PD and non-PD battery packs I use to charge phones and cameras directly, as well as from most standard USB ports supplying 10amps or less. The USB C ports used to charge and operate a camera or computer at the same time will not power this charger. It is designed to work off lower power supplies. Most PD Powerbanks have both high and low power supplies. It takes about 4 hours to recharge BLX-1 battery that has been drained. The Kastar batteries perform identically to the OEM batteries as far as I can tell. The OM-1 camera sees them the same way it sees OEM batteries and reports all the same details. It is as if the battery firmware was identical, but I cannot be certain. I get the same times and usage from either thus far. Time will tell if they are as durable.
