Can I trickle charge my hybrid?

I own a Kia Niro PHEV and about to be out of the country for about seven weeks. I have bought an AA 4.8W solar-powered trickle charger. It includes the ability to use the EOBD socket as wellas normal battery clams and 12v cigar plug.

However, before risking damage to my car I have tried to investigate it's possible use. I had assumed the starter battery would be the standard 12v lead acid unit but I believe the battery is an AGM battery to cater for the intelligent stop/go function. I have two questions. Firstly.am I safe to use this on an AGM battery and secondly, am I safe to use the EOBD socket? The dealer says OK but should connect directly to the battery terminals. Normally I would remove the live connection but don't really want to risk that as it will upset the car.

Your Kia Niro has its starter battery located underneath the rear seat, so connecting directly to it is probably not a realistic option. AGM batteries require a different charge cycle to conventional lead-acid batteries although this is less of an issue when using a trickle charger. Although the dealer has said it is safe to use the OBD port, the ideal option would be to use a smart charger that has a specific program for trickle charging an AGM battery for complete peace of mind.
