Another factor in the math is how much power is being converted going from the Goal
Zero Yeti battery to the device you are powering/charging. In some situations when
running a 12V device directly off the 12V port, there will be no conversion and so no
additional losses. An example of this, is the LAL 350 running off of the 12V port. In
using the USB ports to charge a phone, you add a layer of conversion (12V battery in the
Goal Zero Yeti is being converted to a 5V USB output), which introduces around 10% of
losses. When using the inverter, there are two layers of conversion (12V to high voltage,
DC to AC). The least efficient way of using the battery in the Goal Zero Yeti is to use an
AC-DC adapter off the AC ports, as is the case if you use a phone wall charger to charge
your phone, as it adds yet another layer of conversion in the wall adapter.
So when you’re deciding on what to power from your new Goal Zero Power Station, do
some research into your device’s watt consumption. For more quick tips and learning
