Kastar 4-Pack Battery and LTD2 USB Charger Compatible with Arlo A-2

In this review the focus is on practical backup power and a flexible charger for Arlo Go cameras. The Kastar 4-Pack Battery and LTD2 USB Charger is aimed at owners of Arlo A-2 series batteries and Arlo Go models who need extra runtime and a compact charging solution. The single biggest reason to consider this kit is the combination of four 4800mAh lithium-ion batteries with a dual-port charger that can charge two batteries simultaneously and supports both Micro-USB and Type-C input, making it a convenient replacement and travel-friendly option for mobile or outdoor security setups.

Key Features

• High capacity batteries: Each 4800mAh lithium-ion cell delivers extended runtime so cameras run longer between swaps during extended monitoring.
• Dual charging at once: The LTD2 USB charger can charge two batteries simultaneously, cutting downtime when multiple spares are in rotation.
• Interchangeable charging plate: The charger plate can be changed to fit different battery shapes so the kit is adaptable to compatible Arlo battery models.
• Wide input compatibility: Charger accepts Micro-USB and Type-C inputs and ships with a Micro USB cable for flexible charging options on the go.
• Smart LED display: Intelligent LED indicators show charging status and relative battery capacity so you know when a cell is ready.
• Compact, travel-ready: The charger uses a 5V 2-3A input and 15W power profile, keeping the unit small and easy to carry with camera gear.

Who It's For

The kit is best for Arlo Go owners and users of Arlo battery models listed as compatible who need multiple spare batteries for remote, mobile, or outdoor installations where mains power is not always available. It fits well for anyone who swaps batteries frequently and values the ability to charge two at once to maintain continuous camera coverage.

Those who should look elsewhere are users of Arlo camera models not listed in the compatibility notes or people who require OEM-branded batteries for warranty reasons. If you only need a single replacement battery and do not need the charger features, a one-off solution might be simpler.
