I tested the maximum power output of the new & improved Hardwire Kit specifically designed for the A139 Pro.
In this post I will attempt to confirm & verify the listed power output specifications of hardwire kits that were sent with the following cameras, see attached photos;
6/14/22 A119 Mini 1
7/23/22 A229
11/29/22 A139 Pro
5/12/23 A119 Mini 2
All three HK4 kits have an identical UPC code of 94044-00061.
The HK3-C that was sent with the A139 Pro has a UPC code of 94044-00048.
All hardwire kits have a listed power output specification of 5V2A MAX.
All hardwire kits have a “Quality Control” date code sticker indicating when it was manufactured.
The indicated dates of manufacturer correspond when I received the cameras.
The HK4 kits I received with the A119 Mini 1 & A229 are constructed using 24AWG gauge wire.
The HK3-C & HK4 kits I received with the A139 Pro & A119 Mini 2 are constructed using “20AWG+24AWG” gauge wire, (see attached photos).
The diameter of the 24AWG gauge wire is 4.11mm.
The diameter of the 20AWG+24AWG gauge wire is 4.31mm.
To obtain the maximum power output of each hardwire kit I’ll be using my;
1.) WANPTEK Power Supply set at 12.60 Volts @ 5 Amps.
2.) DROK USB Load Tester set at 5.00 Volts, and I will crank up the Amperage Load to obtain the max power output.
Both 24AWG kits have an identical maximum power output of 2.3 Amps @ 5.0 Volts = 11.5 Watts
Both 20AWG+24AWG kits have an identical maximum power output of 3.5 Amps @ 5.0 Volts = 17.5 Watts, (an increase of 6 Watts).
The maximum power consumption of the A139 Pro in 3-channel configuration is approximately 11 Watts. Shoutout to
@rcg530 for making these beautiful color coded spreadsheets documenting his power consumption testing, (see attached screenshot).
What does this mean?
1.)
If a consumer already had an existing A139, A139 2-channel, A139 3-channel installed in their car with the “old” hardwire kit, and upgraded the front main camera to the A139 Pro they may experience malfunctions due to power starvation from the old hardwire kit being unable to supply sufficient power to the camera.
Endless boot loop (start up & shut down).
Recording malfunctions
Dropping 2nd & 3rd channels
SD Card data writing malfunction.
2.)
If a new first time buyer purchased an A139 Pro, A139 Pro 2-channel, A139 Pro 3-channel from a retailer other than the Official Viofo website like Amazon, and also purchased a hardwire kit, they may have been shipped the “old” 24AWG hardwire kit.
Q:How does a consumer identify if they have an “old” 24AWG hardwire kit only capable of 11.5 Watts max output, or the “upgraded” 20AWG+24AWG kit capable of 17.5 Watts max output?
A: Check the writing on the hardwire cable, (Type-C connector end).
24AWG = Old
20AWG+24AWG = Upgraded
