Quick Answer
For charging ham radios, the best solar-powered options include portable solar panels with DC output, such as the Goal Zero Nomad 7 or Renogy 100W solar panel, paired with a compatible battery and USB output. These setups can charge handheld ham radios like the Baofeng UV-5R or Yaesu FT-60R. Look for a power bank with a high capacity and multiple USB ports.
Choosing a Solar Panel
When selecting a solar panel for charging ham radios, consider the device’s power requirements. A typical handheld ham radio draws around 5-7 watts of power. A 7-watt solar panel like the Goal Zero Nomad 7 can keep a small battery charged during a day of use. For more power-hungry radios or longer operating periods, a higher wattage panel like the Renogy 100W is a better option.
Battery Selection and Charging Techniques
For a reliable ham radio charging setup, a deep cycle battery with a high capacity is essential. A 12V, 7Ah or 12V, 12Ah battery like the Battle Born 12V, 12Ah is suitable for most handheld radios. When charging a battery, use a 10-20% charge to 80-90% charge cycle to prolong its lifespan. This technique prevents overcharging and maintains the battery’s health.
Power Bank and Charging Accessories
A power bank like the Anker PowerCore 20000 with multiple USB ports can charge multiple devices at once. This is especially useful when operating with a team. Look for a power bank with a high capacity and a reliable charging circuit to ensure safe and efficient charging. Some power banks may also include built-in battery monitoring and overcharge protection.
