For example, I regularly plug a Micro USB cable into an iPhone charger and charge with that. Cheap, non phone chargers however, may not be regulated, and that could damage your phone. In short: Any cable or charger from an old phone is fine to use if its Micro USB (same connector).
Untreated surface water in rivers, streams, lakes, and ponds is not safe to drink unless it is treated to remove bacteria, viruses, and parasites.
If you are unsure your pond treatment system is capable. of removing the blue-green algae and the toxins from. your drinking water, you should consider using an. alternative drinking water source or use bottled water. during times of increased algal growth.
