Good point Flp! Could save some lives!
Do not ever depend on emergency lighting or communications equipment that cannot be directly recharged from a source other than the local power grid unless the equipment can also utilize disposable batteries!
Most small rechargeable batteries have a relatively limited capacity compared to inexpensive alkaline cells. Without power to recharge them, they quickly become useless. If their charger must be connected to a source of 110/220 - 60~ VAC, options for recharging will not exist without additional supplemental equipment which may not be readily available during emergencies. Remember, the power grid may be down for days.
The above is particularly true of Induction Charging as used in the present Capstone products.
If you wish to support CAPC by buying Capstone Lighting products, by all means, do so. Used as a night light and/or temporary flashlight or headlight they should be adequate for the purpose.
For the (hopefully never) severe disaster, back these up with replaceable battery powered LED flashlights or better still LED headlamps containing both red and white LED's. Using red LED's at night preserves night vision and are much more effective than white ones.
