Thank you all for superb answers. There's a lot to digest now in every direction - from looking into another flashlight in line with your suggestion, to looking into improving my charging capabilities. It got me to buying solar charging device (Big Blue solar charger, 28W) which also will potentially charge the phone as well. Of course it has its limitations, but it's a good alternative to charge what you already have. Also I will still look into your AA lights suggestions. Some of them are really great, need to dive into that choice and choose wisely. Thanks again! T
