There are some precautions you need to take when using a solar lamp to ensure that there are no unforeseen issues. Firstly, you should verify the runtime of a solar lamp when it is fully charged. This is even more vital if you will be using it in emergencies. Some lamps will only run for a limited time even after charging for an entire day. So you shouldn't use such lamps if you need a lamp that will stay on all night. Portability is another important thing. Some lamps aren't designed to be packed down or moved from one location to the other. Hence, you should take some time to verify the size, weight, and compactness of any camping lamp you will be investing in. Every single ounce should be considered when packing your camping gear. A large or heavy lamp will be difficult to transport.
