A battery operated bug zapper? Where do I sign up?Many (not all) flying pests are attracted to inferred light (IR) and wrapping a IR source with a high voltage or otherwise deadly (to insects anyway) grid is something that home and patio gizmo makers have been doing for decades.The problems with the afore mentioned devices is two fold, they are usually large+heavy and require 120VAC to operate. While they are able to provide almost limitless 'frying power' to 'zap' flying pests replacement bulbs are ether or both very expensive and nary impossible to source/find.Enterprising users could pair one of the devices up with a ~400W inverter and deep cycle battery for bug zapping duties away from 'mains' 120VAC however the size+weight+cost of such a solution might be considered a bit silly at best. (I'll admit to doing this in the past.) :)In 2023 there ought to be a better solution and indeed there is! The device market has many rechargable battery powered devices that use low power+long lasting LED's for the portable and semi portable market.The 'Solar Bug Zapper' (being reviewed here) is one such device.The #1 question might be about the 'use pattern'. When and for how long would someone use such a device?The market is filled with examples of effective solar powered walkway lights. During the day they are charged by whatever available sun they get and at dusk/night they automatically turn on to illuminate the users walkway for a few or more hours (often times until the sun comes up the next day).While I imagine that in a 'perfect world' a 'solar bug zapper' would be used in much if not the same way the problem is that the bug zappers have to not only energize ether electrodes or 'grids' and zap bugs but do this while also supplying pest attracting IR light.Given that the SUN is orders of magnitude brighter than this (or most if not all other) device it ought to be most effective when not competing with the sun and/or placed in partial shade or simply used in the evenings/mornings after sunset or before sun rise.Since the light emitted is intended to attract pests, it might work best placed away from humans and between humans and possible sources of flying pests (like foliage or water/lakes/streams).While with a fully charged battery this device will power the multi wavelength IR LED's and high voltage grid for ~7HRS (without zapping any bugs – which logically ought to use more energy and deplete the battery quicker) operating it with full exposure to the sun only extends its run time by ~30min. (~7.5hrs of run time operating in full sun vs ~7hrs operating in dark room)This by itself really brings to question just HOW solar powered the device is or if it really could be considered 'solar powered' at all. Given the above results I'll be USBC charging my device overnight for campground use. To be fair if given enough sun light hours (days/weeks?) you could fully recharge it using only the solar panel on the top.The device will shut itself off when the battery is depleted.Next to the USBC charge port is ether 2 LED's or a BI-COLOR LED that lights RED when the device is charging via solar or USBC port and lights BLUE when the device is fully charged.I've taken a number of images of both the device in question and of my testing/review setups.Given that I'd decided that the 'solar charging' feature was fairly useless I turned my attention to the USBC charging and wondered if the USBC vs 'regular USB' or 'uUSB' was gaining us anything. To check this out I made use of two different USBC 'fast chargers' that are able to provide up to 45W of USBC power/charging and a USBC testing device.While 'standard USB' power is generally considered 5W I was able to measure ~9W of charging power going to the 'Solar Bug Zapper'. Surely not 'fast charging' however better than the 'microUSB' or 'uUSB' cords/adapters might provide.I tried two different USBC 'fast charging' devices as well as two different USBC cords that are known to provide USBC fast charging to other devices.I did not however time how long it takes to go from a fully depleted to fully charged (BLUE LED) state as I'll likely just plug it in for recharging overnight. I'll assume that like most items it may take a hand full of hours to recharge.Conclusion? While not as bright and powerful as home/patio units that run on 120VAC the device works and ~7hrs of run time ought to cover most peoples evenings/nights use and would be reusable if charged overnight or during the day with USBC.Disclaimer: I'm a retired Electronics industry professional.
