Kastar 2-Pack Battery and LTD2 USB Charger Replacement for Samsung

In this review the Kastar 2-Pack Battery and LTD2 USB Charger is evaluated for photographers who need reliable spare power for the Samsung NX1 and compatible cameras. The bottom line: this kit is for shooters who want a compact, dual-bay charging solution and two 2000mAh replacement cells so they can shoot longer without hunting for a proprietary charger. The reviewer found the combination of Lithium-Ion 7.4V, 2000mAh batteries and a USB-powered charger that accepts Micro-USB or Type-C inputs to be a practical, portable solution for travel and field work.

Key Features

• Dual battery pack: Two 2000mAh Li-ion batteries provide spare power so users can swap cells and extend shooting time without long waits between charging.
• Dual-bay charger: The LTD2 charger accepts two batteries at once and can switch the plate to fit the specified Samsung battery models, saving time for users who charge multiple cells.
• USB input versatility: Multiple charging options with Micro-USB and Type-C inputs let photographers use common power banks or wall adapters rated 5V 2-3A for convenient recharging on the go.
• Smart LED indicators: Intelligent LED display shows charging status and relative battery capacity so photographers can see when each battery is ready without guessing.
• Practical output: Charger delivers 8.4V at 800mA per bay, a reliable charge rate for the listed Samsung batteries while balancing charge speed and battery health.

Who It's For

This kit is aimed at owners of the Samsung NX1 Smart Wi-Fi 4K Digital Camera and anyone who uses the compatible ED-BP1900 / BP-1900 battery models and wants a compact spare battery solution. Travelers, event shooters, and vloggers who need a small, USB-powered charger and two ready batteries will appreciate the portability and the ability to top up from common USB power sources.

Photographers who require manufacturer service, OEM warranty parts, or dramatically faster professional charging may want to consider original-brand chargers or higher-power desktop chargers instead. This kit is best as a convenient, value-minded replacement and travel backup rather than a studio charger replacement.

Pros & Cons
