Rechargeable Batteries Solar Charger

The following solar powered battery charger (pictured above) is a practical preparedness item to have for charging typical consumer-size AA & AAA batteries including C & D.

When the power grid goes down, the sun keeps shining. We can harness that energy. And in this case as a rechargeable batteries solar charger:

Solar 11-in-1 Battery Charger


I have two solar battery chargers that look nearly identical to this one (except they’re an older version that don’t have the built-in meter gauge). They are still working perfectly and I have used them countless times in the sun to recharge batteries for devices including:

– Flashlights
– AM/FM/Shortwave portable radio
– Emergency weather-alert radio
– 2 way radios, walkies

I like the fact that it includes a meter-gauge. It provides reassurance to see the meter reading of the energy being charged.

The meter helps optimize the angle of the solar panels facing towards the sun for highest charge rate.

About the C.Crane Universal Solar 11-in-One Battery Charger with Meter

This high powered solar charger charges two Rechargeable Batteries of the same type and size (D, C, AA, AAA). It puts out about 150mA at ~ 5 volts.

The solar panel is incorporated into the hinged cover which can be angled for maximum sun exposure. Its in-built meter shows you the following conditions:

– The strength of the sun
– The strength of the current out-put from the solar panel
– The time required to fully charge the different types of batteries

This battery charger incorporates a built-in blocking diode to prevent reverse flow of electricity from charged batteries during storage.

Solar USB Battery Charger

Another option that includes solar charging ability (pictured above) for USB devices (and AA, AAA batteries) is the following combination:

21 Watt Solar Charger with 2-Port USB

– Fast charging technology maximizes charging speed
– 2 USB port output
– up to 2.0A max per port or 3.0 A max overall (@5V)
– Will work with any USB device within technical specs.

Smart USB-powered Battery Charger for AA AAA

– powered by USB source
– fits AA, AAA size rechargeable batteries
– 40 minutes to charge 1 battery fully
– 2.5 hours to charge 4
– ‘Smart’ battery charging technology

Note: In reality, charge time may take longer depending on sunlight conditions when using solar panel with USB output.


Rechargeable Batteries

Battery chargers like those listed above will charge ‘rechargeable’ batteries(Ni-MH Nickel-Metal-Hydride).

Here are some of the latest technology Ni-MH rechargeable batteries:
