Here are some common devices and their watt-hour requirements:
Device Power from PPS
Smartphone (8~10Wh) 30+ Recharges
Tablet (25~42Wh) 7+ Recharges
Laptop (50Wh) 5+Hrs
Desktop Computer (100W) 2~3 Hrs
Mini Fridge (30~60W) 4~10Hrs
32” LCD TV (98~156W) 2~4Hrs
Vacuum Cleaner (200~300W) 1~2Hrs
Blender/Processor (200~300W) 1~2Hrs
So when you’re deciding on what to power from your PPS, do some research into your device’s
wattage consumption.
Second, you will need to check the capacity for the individual output ports. For example, the AC
port is monitored by an inverter that allows for 300W of continuous power. This means if your
device is a pulling more than 300W for an extended period of time, the PPS’s inverter will shut off.
Finally, once you know your device is compatible, you’ll want to determine how long you’ll be able
to power your gear from the PPS. Here’s a quick lesson as below.
8. Troubleshooting
If your devices are not recharging from your PPS, follow these steps:
1. Make sure the Master POWER button is turned on.
2. Ensure the Output Port has been turned on. The green LED light on the power button should be
lit up.
3. Check the Battery Display. If it is at 20% or below, charge your PPS.
4. Verify your device is suitable for use with the PPS. All of the PPS output ports have their own
max power capacity. Check the PPS’s Tech Specs to ensure your device is compatible.
If you are still experiencing trouble with your PPS after checking and troubleshooting as below
form, please call our Customer Service Center.
There is 400Wh battery built inside. But when the device draws big power near 300W, the discharge
capacity rate is about 90%. Also, there will be energy loss when battery's DC power transferred to AC
power and different loads also influence the transfer efficiency.
Why the transfer efficiency is only 90% when drawing big from battery?
1) Lengthen battery cycle life
2) Make sure long term storage won't cause battery damage after using
Certainly, low power consumption will drain more energy.
The computational formula of theoretical discharge capacity as below.
discharge capacity = nominal capacity x depth of discharge x transfer efficiency = 400Wh x 0.9 x 0.86
=309.6Wh.
NOTE: the real discharge capacity may be a little different with the ideal value.
NOTE: The AC output power value in LCD maybe not very accurate,specially when power consumption
is low.
