Portable power?

Took me a while to find this

To calculate how long a battery will last isn’t quite as simple as your calculation (despite what a lot of websites say when describing mAh) although the figures you’ve used should actually work

I’m not sure if they still work it out the same way but it used to be a 20 hour discharge to calculate the capacity so any loads larger than 1A on your 20,000mAh battery and the discharge will be quicker than you think but same could be said in reverse, if you are pulling 100mA it might last a lot longer than expected

The camera requires and will only use 1.0 amps. Supplying 2.4 or 4.0 amps has no ill effect on the camera because it will only use what it needs, 1.0 amps.


I’ve measured the camera’s power consumption. It draws about 310mA in ‘Day’ mode, and 430mA when the night-mode IR LEDs are turned on.

Turning the camera ‘off’ has no appreciable impact on power consumption (which is to say that ‘off’ is not really off).

The USB power unit that comes with the Wyze V2 is rated at 1 amp. Wyze chose to provide a 1A unit since (a) it’s a common, inexpensive commodity design and (b) you can daisy chain the power wiring and drive two cameras from a single power unit.

The OP’s 20000 mAh Anker battery pack will power a V2 camera for over 60 hours in Day mode. If the camera is configured to activate the LEDs at night, the run-time will be reduced.


Better check your math. somewhat over 60 hours - not 60 days.

This is perfect thanks for everyone’s information! I checked on my other Wyze v2 cam using its supplied power adapter and the camera is warm as well. I wonder how Blink cameras can provide a long operation on 2 AA batteries. (Information below)

I don’t really need the Wyze cam to be actively recording I just need events to record. I can’t use the IR for night because of the glass on the peep hole and also the fact it will be pressed up against the tiny hole.

[Blink Indoor and XT cameras can last for up to 2 Years* on a single pair of non-rechargeable AA Lithium batteries. This is defined as 40,000 seconds of Motion Clips and Live View. This is the average use for the majority of Blink camera systems.

A new set of non-rechargeable AA lithium batteries should last for a total of 40,000 seconds of motion-activated video recordings and/or live video. We define standard or typical use as approximately 10, 5-second video events per day]

60 hours in day mode is what he stated.

Yes - 60 hours. (20000/310)

Geez, must be too early in the day for me to mis-read it that badly!

I meant at most 1.0 amps. Certainly it will easily use less if that’s all it requires.

Not initially. He fixed it.

Is there a way to turn off continuous recording and only have it record events?

In the app (Android) for each camera, go to settings, Advanced Settings, Local Storage.
You can select Record events only or Continuous recording.
I assume the iOS app is similar.

Won’t make any real difference to power consumption as the camera is still constantly on & processing

To have a low power camera that only activates on motion it needs to have a pir

Per the Wyze FAQ:

What are the power requirements and power consumption of the WyzeCam? Can it be used with a power bank?

The WyzeCam uses 5V 1A DC power through a micro USB port. Each WyzeCam comes with a 6-foot micro USB cable and 110V wall outlet plug to plug into a wall outlet. You can also use a power bank or 240V power converter to power your WyzeCam.

The power consumption is between 2-4 watts, depending on whether night vision is turned on.

How long will a 10000mAH or 20000mAH power bank power the WyzeCam?
A 10000mAh power bank will power the WyzeCam for ~16 hours. A 20000mAh power bank will power the WyzeCam for ~33 hours

Has anyone used a solar charger with a usb power bank to power a Wyze cam?

You can look around through some of these threads. There are several success stories about solar powered cams, but not sure about the solar plus a power bank combo idea. :slightly_smiling_face:


There’s a post on this forum somewhere describing the use of a Raspberry Pi power controller for such a setup. The controller manages the charging of a battery (from solar panel) and generates a regulated 5VDC supply with which to power the camera. It’s a nice solution. I can’t immediately find the post, but Ms. Google should be able to locate it.

Maybe not this one particularly but couldn’t something like this work? There are others that have a roll out attached solar panel.

In general the power banks with attached solar panels do not charge very quickly via solar. For the first one you linked to the seller states it charges at max 120mA, so even during full sun it would be losing charge to a Wyze Cam drawing 400mA.

The second one purports to charge at up to 2A, but in reality that will be much lower with a fixed location and angle. It may allow the power pack to last multiple days, but eventually the constant power draw of the camera will overtake the short bursts of power provided by solar during the day.

If you want to try it and report back it would be an interesting experiment to see how long it lasts. I’m always playing with off the shelf equipment to see how it compares with custom built systems, but I haven’t tested a fold out solar charger yet :thinking:. The key with a truly standalone solar system is to have enough battery capacity to last through several dark days, while having the solar capacity to fully recharge that battery in a single day once the sun comes out again.
