For bank bank capacity , we have a formal to count Power bank capacity calculation method. After the power bank is fully charged, connect the meter (data first reset) with theappliance, then discharge to the stop output. Method 1: power bank capacity = measurement mAh * the output voltage+ battery voltage ÷ efficiency. Method 2: power bank capacity = measurement mWh ÷ battery voltage + efficiency. normally power bank output voltage is about 5V, internal battery voltageis about 3.7V,efficiency about 85-90%
I Googled DCV's and came up with Directional Control Valve for Hydraulics, but somehow I don't think that is what you are referring too. I am assuming that you mean if you put 5 volts in the variable DC controller, will you be able to get 20-30 volts out?. Not unless it is a boost converter, and the DC controller I showed (the RD6024) is not a boost controller, it is a buck converter. A buck converter only puts out what is put in, and allows you to go down to 0 volts, but not go above the voltage you input. I hope I understood what you meant by DCV's... The DCV's is what is throwing me off a bit, as I have never heard it put that way before. If you put 5 volts into a DC converter, and want 20-30 volts out, you would need a Boost converter, or a Buck-Boost converter to do that. The Riden converters are Buck only converters. Also, the DPS5020 that I did a video about is also a Buck only converter, so if you put 5 volts in, you will only get 0-5 volts out.

Thank you for your comment and bread-down - much appreciated. 👍

interesting video
Thanks Joe. I am glad it was interesting. I enjoy capacity testing batteries, so just testing to see what people want to see. 🤔👍
5000mAh/1000*3.7V/5V*0.85 = 3.145Ah expected value for dc/dc efficiency 85%, so most of them fair enough.
Thanks for the info - much appreciated. 👍
you are right
Steven, a few weeks ago you showed a variable DC controller. Does it increase the DCVs out? Ok, if I put 5DCVs in, will it turn up to 20-30DCVs.... ?
Thanks Buzz, could you break that down a bit?, I am not sure what you are asking.... 🤔
Are you talking about the RD6024 Power Supply?
