The Objective2 strictly requires an AC‐to‐AC transformer, with minimum 13.50 VAC output (14 VAC+ recommended).
AC/DC adapters are very different from AC/AC adapters. Manufacturers commonly abbreviate and refer to all types simply as "AC Adapters", which gives no indication of their actual output. Most adapters are in fact AC/DC type, which supply DC current. These power adapters are used with typical electronics such as laptops, game consoles, computer peripherals, etc., and are not compatible with the Objective2.
The Objective2 accepts the following power adapter characteristics:
- Type: AC‐to‐AC Transformer (AC/AC, not AC/DC!)
- Voltage: 13.50 VAC minimum, 22.50 VAC maximum
- Current: 200 mA minimum, no maximum
- Plug Size: 2.1 x 5.5mm (Inner Diameter x Outer Diameter)
Choosing a Suitable AC/AC AdapterEdit
The following table is a user compiled list of power adapters suitable for use with the Objective2.
Select an adapter with the correct plug type for your country. Refer to the following resources for help with plug types:
- Power Plugs by Country - Electric Power Around The World
- Comparison of Plugs - AC Power Plugs
If no adapters are listed with your country's plug type, try to select a foreign adapter with the correct Input Voltage and Frequency for your region. Then use a plug converter, such as the Kingsmart UNI001 .
As a last resort, you may need to use a Step-Down transformer in conjunction with one of the commonly available North American power adapters. One example is the Simran SMF-200.
