The reliable power supply for telescopes and cameras with many extras!
The Dynamo Pro Power Tank has two sockets which accept a normal cigarette lighter plug. So this portable battery provides a reliable supply when 12 volts is required outdoors. Two USB ports mean additional devices, that you would normally connect to a laptop, can also be operated. The Power Tank can be easy recharged at home using the power cord supplied. It comes with various adapters included for this task, so that it will always work abroad. An LED shows the charging status of the battery.
The Power Tank also has a couple more features that go beyond purely astronomical use - it can also be used as a very powerful torch, there is a radio included, and there is a red flashing light mode that would be useful for securing an accident scene, for example. It is worth having the Power Tank handy in your car at all times and not just for when you are going observing.
Our expert comment:
Please consider the following advice to improve the lifetime of your battery:
- Never discharge your battery completely. Turn off your mount before. So you can protect your mount from overvoltage.
- Do not store the battery, when it is empty.
- Do not charge the battery too long. Turn off your charging station as soon as the battery is fully loaded.
