The best hardware products of the past decade were more convenient.
AirPods: not better audio. Wireless audio you didn't have to think about.
Instant Pot: not a better pressure cooker. A pressure cooker you couldn't mess up.
I think the pattern: remove friction, not add features

6/ Getting thermal management right in concealed products is one of the things we've been specifically working on. /end

[Bikash Agrawal @agrbikash]

5/ This is why thermal management is one of the three core engineering challenges of wireless charging in non-phone products, and why you can't just "add Qi" to an existing product without rethinking the internals.

[Bikash Agrawal @agrbikash]

4/ For a sealed product — one with a battery inside and no ventilation — that heat has nowhere to go without deliberate thermal management design. Ignore it and you degrade the battery faster. Design it wrong and you create a safety issue.

3/ The efficiency loss becomes heat — not just in the charging pad, but in the device itself. For a phone sitting on a flat pad with airflow around it, this is manageable.

[Bikash Agrawal @agrbikash]

2/ Wired USB charging systems achieve roughly 92–95% efficiency. Qi wireless charging achieves roughly 80–85% efficiency in typical consumer implementations. That gap is real.

[Bikash Agrawal @agrbikash]

The reason wireless charging generates heat- and it matters for product design. A thread.
1/ Wireless charging uses electromagnetic induction to transfer power. Like any energy transfer, it's not 100% efficient- energy is lost in the coils, in the air gap, and in the receiver.

[Bikash Agrawal @agrbikash]

We talked about manufacturing partner dynamics. Got into why consumer electronics companies leave product categories behind. Shared what electromagnetic induction and Faraday have to do with what we are building. Articulated something people already feel.

Five weeks of posting daily-
The posts that get the most engagement are the most honest ones.
The audience isn't looking for a startup highlight reel. They understand the gap is real and watching someone try to close it is interesting. That's the whole promise. Keep it honest.

[Bikash Agrawal @agrbikash]

Founders-what's the metric you pay the most attention to when you have nothing to ship yet?
For me right now it's depth of engagement over breadth of following. Ten people who understand exactly what we're building and why it matters are more valuable than a thousand others.

[Bikash Agrawal @agrbikash]

Conversation I had with a manufacturing partner few weeks back:
Me: Can we get samples done in X weeks?
Partner: Yes
[Three weeks later]
Partner: We found something
This is hardware. Every "yes" comes with a footnote i.e. a problem that reveled after three weeks

[Bikash Agrawal @agrbikash]

The move fast and break things philosophy is actively dangerous in hardware.
Hardware forces patience not because founders are less ambitious, but because the medium doesn't forgive speed the way software does.

[Bikash Agrawal @agrbikash]

In software, a bad push can be reversed. Users are frustrated for an hour; you ship a fix.
In hardware, a bad decision made in week three has consequences in week thirty-six- after tooling, after component orders, after the manufacturing run.

[Bikash Agrawal @agrbikash]

Wireless Charging still hasn't reached most of the things you use daily.
Technology diffuses slowly, then all at once. We're in the "all at once" part for this next wave.

[Bikash Agrawal @agrbikash]

Electromagnetic induction- the physics of wireless charging-was first demonstrate by Michael Faraday in 1831.
The Qi wireless charging standard reached 4 billion consumer devices by 2024.193 years between the discovery and mass consumer adoption.

[Bikash Agrawal @agrbikash]

5/ Which creates a real, structural opportunity: solve the problem once, manufacture at scale, bring the solution to categories that have been waiting without knowing they were waiting. That's the gap. That's the business. /end

[Bikash Agrawal @agrbikash]

Why the consumer electronics industry keeps ignoring entire product categories- a thread on market incentives and the gaps they create.
1/ Large consumer electronics companies optimize for volume and margin. Low margin don't attract R&D budget the way flagship categories do.

[Bikash Agrawal @agrbikash]

4/ That's not consumer preference. It's organizational incentive. Companies invest where the payoff is largest. The $30 product doesn't move the needle.
