I'm just getting into the hobby of RC Planes and FPV drones so wanted to start by getting a good quality battery charger. I've just received delivery of the ISDT K4. Reviews of early samples were generally positive with a couple of caveats - it was described as being good at it's main purpose of charging batteries but some people complained it didn't offer the option of connecting to your iphone/ipad using ISDT's iLink App or allow charging over USB. I can confirm that my charger came with the latest firmware pre-installed and it does connect to my iphone and allow charging over the USB-C port so the latest update must have fixed those issues. Build quality looks very good - my only negative is that I would have liked an on/off switch rather than just pulling out the lead. I'm in the UK so did need to purchase a C5 power cable separately.
