Smartphone Charger RAVpower 30W Dual USB Turbo Wall Charger (Should provide QC3@9V/12V, but only provides 5 V on both ports) I put the Pinecil through its paces, and and although the device is fully open source, give it a teardown for good measure. Spoiler: it’s my new favorite. If you want the designs of the cores themselves, many are proprietary, but many are open or licensable. https://riscv.org/exchange/?_sft_exchange_category=core If you want the source to the cores like C906 or C910, companies like Alibaba publish those under open licenses, like https://abopen.com/news/alibabas-t-head-releases-c906-c910-risc-v-cores-under-a-permissive-licence/ and you can find synthesizable RTL at https://github.com/T-head-Semi/openc910 as one example. Sure, if there are two PD65 20V chargers that are similar in price, and one is GaN, this is generally a good choice.

Zendure Power bank like this one does not work. It does not appear to be USB-C PD 3.0 compliant. Only the USB-A port seems to work at lower QC voltage. It does not deliver USB-C 20V-5amps or USB-C 20V -3amps. Tentative support: EPR 140W/28V PD3.1 chargers + EPR cables are theoretically supported in hardware and IronOS firmware. It is really making ‘it’ work better if the ‘it’ was awful to the point of rebuild from nearly the ground up, with just a little of the the ‘it’ left in… Magnetic USB-C cables with removeable connectors are not recommended, and are not USB-IF compliant.

Phone chargers are too weak, most are only 12V 1.5 amps which is too low and prevent proper Pinecil operation.

If you have a Pinecil V1, there isn’t much reason to upgrade to V2. The extra power (88W) is nice to have, but how often do we really need it? On the other hand if you are looking for a soldering iron, then Pinecil V2 is an ideal starter iron. We get a low cost iron, with high-end features.

Will Pinecil work with regular USB-C PD 65w 20V-3.25A chargers also? Yes, as long as it supports PD (power delivery protocol). A short press next to the soldering iron icon starts the tip heating, and the temperature is displayed on the screen. I timed its heat-up from ambient to 320 °C at about nine seconds, which is not as fast as some high-end irons, but certainly no slouch. from a 20V capable USB-C PD charger or power from DC barrel charger that is the appropriate specifications. The screen displays the voltage from the charger. most PC & laptop ports don't work as they are only 5V which is good enough for simple Firmware updates but not to provide the constant higher power a "resistance" type of soldering Iron needs to maintain heat.Every maker has their preferred soldering iron tip, and the Pinecil V2 comes with a decent conical short tip that will do the job. It isn’t the most precise tip, but it is able to solder through hole components, and the GPIO of a Raspberry Pi. If you are truly “in the field” with no access to an outlet, you can power Pinecil V2 from a USB C powerbank, as long as it can produce the necessary voltage. You can also use LiPo batteries in 3 / 4 or 5S configurations, or in a pinch an 18-20V Lithium Ion tool battery can be used.
