The bottom line: this kit is for shooters who require multiple spare batteries and a compact charger that reports charge status and remaining capacity. It replaces single batteries with a set of four 7.4V 2900mAh cells and includes an LCD AC charger with a foldable flat pin, making it a practical, space-conscious option for extended shoots and travel.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eBattery Type:\u003c\/strong\u003e The included lithium-ion batteries are 7.4V and 2900mAh, providing long runtime between swaps for DSLR shooting sessions.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e4-Pack Convenience:\u003c\/strong\u003e Four identical batteries mean fewer interruptions on location and a simple charging rotation to keep a camera ready.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eLCD AC Charger:\u003c\/strong\u003e The charger shows charging status and battery capacity on an LCD so users can verify state of charge before heading out.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUniversal AC Input:\u003c\/strong\u003e With 100~240V 50~60Hz input the charger can be used internationally with no separate transformer for travel.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCompact Storage:\u003c\/strong\u003e A foldable flat pin on the charger reduces bulk for packing into a camera bag or carry-on case.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is best for photographers using compatible Pentax cameras such as the 645D, 645Z, K-1, K-3, K-5 series and earlier models who want multiple spare batteries and a single, informative charger to manage them. Wedding shooters, landscape photographers on multi-day trips, and anyone who prefers having replacement power on hand will appreciate the 4-pack approach.\u003c\/p\u003e\n\u003cp\u003eIt is less suitable for users who only need one spare battery or who require original-brand batteries for warranty reasons. If you need a charger that accepts very different battery sizes or a multi-slot rapid charger for simultaneous charging of more than one cell, this single-slot AC charger may not meet that specific need.\u003c\/p\u003e\n\u003ch2\u003ePros \u0026amp; Cons\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePros\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eMultiple batteries in one kit reduce downtime and provide practical redundancy during long shoots.\u003c\/li\u003e\n \u003cli\u003eClear LCD on the charger makes it easy to check charging progress and capacity without guessing.\u003c\/li\u003e\n \u003cli\u003eWorldwide AC input and a foldable pin make the charger travel-friendly and compact to store.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCons\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eThe kit uses a single-slot AC charger, so charging four batteries requires consecutive charging sessions rather than simultaneous charging.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n \u003ctr\u003e\n\u003ctd\u003eBattery Type\u003c\/td\u003e\n\u003ctd\u003eLithium-Ion\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eBattery Voltage\u003c\/td\u003e\n\u003ctd\u003e7.4V\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eBattery Capacity\u003c\/td\u003e\n\u003ctd\u003e2900mAh\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eCharger Input\u003c\/td\u003e\n\u003ctd\u003eAC 100~240V 50~60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eCharger Output\u003c\/td\u003e\n\u003ctd\u003eDC 8.4V 800mA\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003ePackage Contents\u003c\/td\u003e\n\u003ctd\u003e4-Pack Batteries and 1 LCD AC Charger Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eOur Verdict\u003c\/h2\u003e\n\u003cp\u003eThe Kastar 4-Pack D-Li90 kit is a cost-effective way to keep compatible Pentax cameras powered during extended outings, providing robust 2900mAh capacity and a charger that displays status and capacity.
