I've been thinking about getting a lamp with a battery for a long time because I'm often fishing and you don't know what's going to happen this winter, even if I'm anything but a prepper, but the way the BNA recommends preparing at the moment can do it but no harm. The light can be switched from pure white to orange and is dimmable, which I find very pleasant because it is quite glaring at the highest level, the light color of white is pleasant on the eyes and you can use it very well. The sound quality from the loudspeaker is surprising good and also at full volume, which is not exactly quiet and discreet, the Bluetooth connection works without any problems with my xiaomi redmi note 9 pro and I think all other cell phones, tablets etc. shouldn't cause any problems either. The built-in power bank charges my cell phone with about 2A, which is more than enough to get a little power on the device in an emergency. I only measured the light duration subjectively, but I left it dimmed to half that one night and after 12 hours the lamp was still lit, which is definitely longer than my old Osram neon lamp, which was operated with 4 D cells and unfortunately died a few months ago water was not a good combination that shouldn't be a problem with the new one since it is very well protected with rubber caps etc. Clip and clear purchase recommendation even if the price is a little deterrent at first.
