My Journey 1000 arrived in time to be exposed to low temperatures (highs in the upper 20s and lows in the teens), In the week leading up to Christmas 2022, my area of the Northwest a few days of low temperatures and wind chill — which neither I nor my Journey 1000 were out in. This flashlight has yet to be recharged since it arrived. Now, the only question is when using a 20 watt silicon charger or a 30 watt GaN (gallium nitride) charger is how much less charging time when using these chargers. Observe and learn, I guess. I really like how bright this flashlight is on low and high settings.
