of solar AA battery chargers varies from product to product.
Some of these products are able to charge almost any standard battery,
while others are limited to only AA batteries. Each device contains a
solar panel which generates energy to charge the batteries, although
the panels themselves also vary significantly.
Some of the panels are
quite thin and flexible and can be either folded or rolled up, while
other products contain panels that are basically smaller versions of
traditional solar panels. The thinner solar panels are normally in the
products which are designed only to charge AA batteries, as these
batteries require much less energy to charge than larger batteries such
as C or D. The solar universal battery chargers which are capable of
charging larger batteries at least have a much larger panel than simple
solar AA battery chargers.
Powerfilm Solar AA Battery
Solar Panel Charger
One of the best
battery chargers one the market today is manufactured by Powerfilm.
Powerfilm produces a large line of foldable, thin film solar chargers
for a variety of devices. They are one of the leading manufacturers of
thin film chargers, and are renowned for the efficiency of their thin
film solar panels.
uses one of these same foldable, thin film solar panels, which is sewn
directly into the fabric of the charger. This charger is extremely
lightweight: in fact, it weighs less than the 4 AA batteries it can
charge. It can be fastened to a backpack to use on the move, or fixed
to any other surface to ensure it doesn’t blow away.
The manufacturers claim
that in full sunlight, this product is capable of providing a full
charge to two AA batteries in 3 1/3 hours or four AA batteries in 6 2/3
hours. However, this seems to be a worst case scenario, as most
batteries can receive a full charge in less than two hours. One of the
biggest advantages of this charger is that it has a much larger solar panel
than other products while still remaining incredibly portable due to
the solar panel being able to fold.
In fact, when folded up,
this product is small enough to fit in most any jacket or pants pocket.
This charger usually costs between $60 and $90, which makes it one of
the more expensive products available, however it is also one of the most reliable and
efficient chargers on the market as well and comes with
two Sanyo rechargeable batteries.
UltraLast Green Solar 2
If you’re looking
cheaper solar AA battery charger, then the UltraLast
might be the perfect product for you. This
charger is normally
available for under $20, which makes it one of the cheaper chargers on
the market. This price also includes two rechargeable batteries, as
well as USB and mini USB attachments so you can also charge other
devices with it.
However, you should be
aware that you will get what you pay for. The UltraLast Green is a
cheap option when compared to other chargers like the PowerFilm, but it
also charges batteries much slower than the more expensive models. This
charger is only capable of charging two AA batteries at a time, and you
can expect it to take between eight and thirty hours of direct sunlight
to provide a full charge.
This is mainly due to the
fact that this product has a much smaller solar panel, which closely
resembles a miniature version of a standard solar panel. There are also
many other similar chargers on the market, such as the Kodak
KS100-C+2 Solar Charger,
but the UltraLast is one of the best products in this
The only thing to beware
of when buying any of the smaller, cheaper chargers is that they can
take a very long time to charge even two batteries, so don’t expect
them to work miracles. This charger might be much cheaper than the
PowerFilm, but you can charge up to four times as many batteries in the
same time with the more expensive models.
Solar Universal Battery Charger
If you’re looking
reliable solar charger that is capable of charging more than just AA
batteries, then you should have a look at the Goldmaster
battery charger. This product can charge four D, C, AA, or AAA
batteries at one time, which makes it much more versatile than the AA
That said, one thing you
should be sure to take note of is the fact that you must charge four
batteries at a time and they must be one type of battery, i.e. four AA
or four C batteries. This charger also comes with adaptors to connect
and charge almost any other handheld electronic device. One of the few
drawbacks to this product is that the charging capabilities are still
somewhat limited due to the standard solar panel.
Although this panel is
much larger and therefore stronger than in the smaller AA chargers, it
is still no match for the larger, foldable thin panels in the Powerfilm
products. The only other negative is that there is no light or meter to
tell you when the batteries are charging or how much charge they have,
so you must take the batteries out and test them to see if they are
fully charged or not. However, this product still costs less than $30,
which makes it quite a good, versatile charger for the price.
