That was exhausting to type.
If only there was a thread that explained in fully on the best way to wax a chain.

is also the interface that Shimano's Di2 programming software needs to communicate with the battery and Di2 components like shifters and derailleurs.
So it isn't unreasonable to charge the battery in the same way. However, not all PCs have USB ports capable of delivering a stable current, especially laptops, and this (or an inferior 120V AC to 5.5 V DC wall wart) is a common cause of incomplete or failed charging.

can be okay with charging my di2?

If Shimano is going to release a USB-capable charging product, it needs to work safely with ALL USB ports, laptop or other. FULL STOP. It's also not that hard to do just a little more expensive.
As far as how the lower current can cause a fire, I'm speculating, but it likely goes back to a crappy charger design. The dc-dc convertor in their charger is probably becoming unstable at low current levels and dissipates all the incoming power as heat rather than passing it into the di2 battery.

+1 for the crappy charger design though.

Anyway, this makes me glad I chose SRAM AXS as I've been charging the SRAM batteries from my desktop pc.

Shimano is also generally more expensive, but man, Ultegra and DA are pieces of art.

I can believe Shimano build quality is above SRAM, but I'm very happy with SRAM Force. It was faultless for me last season and I much prefer it to the Shimano 105 R7000 on my other bike - mainly due to the electronic shifting and paddle interface. I haven't ridden the latest Di2 groupsets, but they do look good.

With SRAM, you remove the batteries and take them to the charger, yes? Is it the same with Shimano, or do you have to bring the charger to the bike?
