The Uniden UPP80S solar power bank is a geek gift. It is certainly one of the more useful power banks.
The Uniden UPP80s is an 8000mAh battery with a monocrystalline
20 micro-panel solar charger, two USB-A ports (5V/2.1A total), a micro-USB port
(also for charging), a 2x LED flashlight, compass and IP54 water/dust
It is precisely what Tom Hank’s needed in Cast Away – mind
you, mobile phones were not around so much in 2001.
Let’s go into use cases first – a solar power bank.
Well with 2.1A and 8000mAh you could connect it to a
security camera – perhaps a better idea than just a solar panel recharger (shootout
because the power bank stores excess
energy for a rainy day.
Or you don’t want to run a USB cable from your GPS or Dash
cam to an inconveniently positioned utility socket. Just leave this on the
Every uni-student should have one too.
Every camper, hiker or fisherman
could use this too – 8000mAh will top-up a flagship smartphone at least twice, and it charges itself as well. It has a carabiner
clip to go on the backpack.
It may be good to have around for blackouts to keep a phone or another USB device going.
We exhausted the battery (two Galaxy Note9 charges to be
precise). Mind you at 5V/2.1A a Galaxy recharge took about 7 hours.
We set it up on an east/west facing table which received
sunlight for most of the day (say 7 AM to 7 PM
– 12 hours. We were a little alarmed at first when it only had under 50% charge
by the end of day one!
At the end of day two – sorry not full either but three LEDs
(out of four) were solid. When we checked at the end of day three – all was
fine. We estimate about 24 hours all up.
We estimate that the solar panel produces about 5V/.3A
We then read the manual
Charging via solar panel is an alternative method of USB
charging. The solar charging time depends on the intensity of the sunlight,
which varies at times. We recommend the USB charging as the primary source of
