Many solar energisers are low in power and/or utilise solar panels which are inadequate to keep the battery charged. We have designed the Fire Drake energisers to operate at popular power levels, suitable for a range of applications, with panels carefully matched to replace the energy used while operating. Available in 0.15, 0.25 or 0.5 output joule models, with 2.5, 5 or 10-watt solar panels. A battery charger is also included to ensure the battery is charged during the winter months and when the energiser is not in use.
