Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices with a 30-pin charge port, a connector can be used to charge with the Lightning Connector. The Plugs Must Be The Same In order for a charger to be used on a different device, it’s important that the plug of the charger (the “head”) fit securely into the charging port of the device. Micro USBs are the same across the board as far as charging heads, while laptop chargers are often specific to both make and model. However, the plug fitting securely is only one part of the equation. How Voltage and Amperage Matter Somewhere on the power brick of the charger you will find a label with the charger’s voltage (V) and amperage (A). For laptop chargers, this charging brick is often halfway down the charger and typically looks exactly like it sounds – a brick. For other types of chargers, like a smartphone charger, this information is usually found at the base of the charger, where it would meet the wall. For the device you are trying to charge, the voltage and amperage required will be found on the battery that came with the device or on the manufacturer’s website.
