The high-quality lithium ion batteries used in portable solar power stations will not explode or catch fire under normal conditions. However, there are some cases where they can be damaged due to improper use or storage. We recommend that you follow these instructions to avoid damaging your portable solar power station:
1) Keep all devices dry; do not expose them to rain or water; this includes dustproofing and waterproofing
2) Do not store devices in extremely cold (below 0°C) or hot (above 40°C) environments; if storing for more than 1 month please charge it before putting away
3) Do not store devices on concrete floors; it is better to store them on soft surfaces like carpeted floors or bedding such as mattresses
