content: Hello!I am designing a new powerbank with special features like passthrough mode, bidirectional port with adjustable output voltage and current up to 120W, solar charging...So i created a short survey to better learn about buyer preferences and habits to improve my product.Survey link:https://tally.so/r/npMzQZThanks a lot for solving this survey and helping me out. 👍 If you have any questions or opinions please post them in the comments.

content: What does age and gender have to do with designing a battery pack? Secondly, with so much to choose from already on the market, what would makes yours any different?

content: you must be new to evil ass sales shit if you are asking about what age and gender has to do with marketingThe level of design on these power bank things is often deciding on what form factor to stick several china or other low cost modules together in.

content: My favourite power bank has :- 99.9 Wh in a 4s2p configuration- USB-C up to and including 100W output- USB-C input to charge at up to 40W- 2 x USB-A that do the fancy samsung fast charge stuff I never use or 5V @ >= 2.4AMy biggest gripe is even with top quality cells from a reputable dealer they slowly go out of balance over a couple of years. So some form of charge balancing would be nice. Or perhaps a BMS that isn't leaking current while monitoring.I'm not doing some bullshit survey, particularly where the first questions are demographics.

content: I like USB batteries that wake or turn on when the load is switched on. They are hard to find.

content: Quote from: BradC on May 11, 2025, 04:25:45 amThanks for the reply.Yeah these features are pretty close to what i needed in a powerbank when i was determining specifications besides the adjustable port for powering laptops and soldering irons for example.I was also concerned about the cells eventually going out of balance so i used a BMS with active balancing.Just to be clear the survey is completely anonymous.The age and gender in the survey is just to determine what age group prefers what features and habits in powerbank usage, to better position in the marketing.

content: Please perform a survey, evaluation, and criticism of existing battery power banks on the market. Report their benefits and limitations.This must be done in order to compare your product against.If you do not perform such an evaluation, your product proposal cannot be considered serious.

You haven't even nailed down the product specs and already you're thinking about marketing? Talk about putting the cart before the horse.
