Kastar 2-Pack Battery and LTD2 USB Charger Compatible with Arlo

In this review the Kastar 2-Pack Battery and LTD2 USB Charger is presented as a practical replacement for owners of Arlo Ultra and compatible cameras who need reliable spare power and a flexible charging solution. The reviewer finds the package valuable for users who rotate batteries regularly because it pairs two 4800mAh lithium-ion batteries with a dual USB charger that can handle two cells at once, and it offers both Micro-USB and Type-C inputs. Overall, the main reason to buy is the convenience of simultaneous charging and the ability to swap charging plates for different battery types.

Key Features

• High capacity batteries: Each lithium-ion battery provides 4800mAh at 3.85V to extend camera run time between swaps.
• Dual battery charging: The LTD2 charger can charge two batteries at the same time so you can keep spares ready without waiting for a single slot.
• Changeable plate: The charger plate can be swapped to accept different compatible battery shapes, increasing flexibility for mixed camera setups.
• USB power input: The charger accepts Micro-USB and Type-C input and runs from a 5V 2-3A source, so it works with common phone chargers and power banks.
• Clear LED indicators: Intelligent LED display shows charging status and gives a quick idea of battery capacity while charging.
• Portable design: The charger is light and easy to carry, making it convenient for field use and seasonal deployments.

Who It's For

The Kastar kit is best for Arlo Ultra, Ultra Plus and other listed Arlo camera owners who maintain on-site battery swaps and want a compact way to recharge multiple batteries. It suits hobbyists, installers, and homeowners who use battery-powered security cameras and value having two charged spares ready to prolong monitoring without downtime.

Those who should look elsewhere include users who prefer smart dock charging integrated into the camera system or need OEM-branded batteries for warranty reasons. If you rely exclusively on wired power or solar panels for continuous camera operation, extra removable batteries may be unnecessary.
