Kastar 3-Pack Ei-D-Li1 Battery and AC Wall Charger - Extended Power

In this review the Kastar 3-Pack Ei-D-Li1 Battery and AC Wall Charger is presented for photographers and field techs who need reliable spare power for older Pentax cameras and certain Trimble, HP and Molicel devices. The single biggest reason to buy is straightforward: three 7.4V 2600mAh lithium-ion batteries plus a compact foldable AC charger give long runtime and simple recharging so users can keep shooting or working without hunting for replacements. The review focuses on compatibility, run time, and the convenience of the included charger.

Key Features

• High capacity battery: Each 2600mAh lithium-ion cell offers extended runtime compared with typical OEM capacities, reducing interruptions during long shoots or field work.
• Compatible with multiple models: The pack lists compatibility with Pentax D-Li1 series and numerous Trimble, HP and Molicel models, making it a practical spare for mixed-equipment toolkits.
• Included AC charger: The charger has a foldable flat pin for compact storage and an output of DC 8.4V 600mA to recharge batteries at a moderate, battery-friendly rate.
• Wide input voltage: Charger accepts AC 100~240V 50~60Hz so it can be used in regions with different mains voltages without a separate converter.
• Charging indicator: An LED shows red while charging and green when ready, making it easy to check battery status at a glance.

Who It's For

The Kastar 3-Pack is best for photographers, surveyors and field technicians who use older Pentax cameras or compatible Trimble and HP units and need multiple spares to swap in during long sessions. It also suits owners who prefer buying batteries in sets to avoid frequent reorders and those who value a small, travel-friendly charger with a foldable pin.

This pack is not aimed at users who require a car adapter or European plug in the box, since those are not included, or buyers who must match an exact OEM battery label for warranty reasons; such users should look for factory originals or kits that include vehicle charging accessories.
