“The Nomad 28 Plus features an auto restart that’s smarter than anything else on the market. With the ability to track power flow history, it knows the difference between a device that has reached a fully charged state and one that disconnects due to environmental causes, i.e. lack of sunlight, shadow, solar eclipse, etc. When the latter is detected, it automatically reconnects the charging device, no extra work on your part is needed.

The Nomad 28 Plus is splash-proof and there are practical cut-outs at the corners. On the back of the Nomad 7 Plus is a storage compartment with zipper, in which the device can be safely stored when charged.

Question: Is it possible to charge any device directly with a solar panel when the weather is changeable?
Answer:
“Small USB devices, such as cameras and MP3 players, require 1-2.5 W of constant power to charge.
Our solar modules can easily deliver this amount of energy, even if the conditions are not optimal. Smartphones
and tablets have a higher energy requirement. Usually around 5 W of constant energy. A solar panel with a
nominal value of 7 W produces only 5 W in perfect sun conditions, and since smartphones are very sensitive
to their power requirements, charging can be stopped if the constant power supply is interrupted, eg. when a
cloud is in front of the sun.”
For optimal operation, we recommend using a Goal Zero power bank as a buffer instead of directly charging from the solar panel your device for the following reasons:
“Heat and batteries are not compatible. Precision electronics should not heat up. When charging directly
from the solar panel, make sure that the device with its battery is in the shadow of the solar panel.The shadow of the inclined module is a good place. Do not store the devices next to the modules while charging. The heat would reduce the life of the battery.”
“If clouds pass or the weather changes, the charging process of your device can be interrupted.
In such cases, it often happens that the phones or GPS devices reject the charge. This means that your devcice
is connected but not charging. Goal Zero powerbanks ensure a constant charge regardless of the weather
conditions. The chargers / battery chargers from Goal Zero are well-charged with Goal Zero solar modules
regardless of the conditions – they never reject a charging attempt.”
“You may not want to sit in the sun if you want to use your phone while charging. Using a Goal Zero battery
allows you to be anywhere”
“You may use your phone or GPS device during the day and charge it at night. The solarpanel will not work at
night, but the Goal Zero Powerbank will work anytime.”
