Optimate 2400mA USB Charger & 3-LED Battery Monitor

The portable & compact SAE to USB 2400mA charger for safe and fast charging of any USB device, including your phone, camera or GPS.

• Connects to battery lead with industry standard SAE 2-pin connector – Seals perfectly when mated with OptiMate SAE!
• Charges 1x USB device with up to 2400mA current available (or get optional O-110 USB splitter and charge 2 devices). – Charge current adapts to connected device for safe recharging.
• Creates weatherproof seal against inserted USB cable, or ‘rideproof’ cap seals when not in use – Worry free phone, camera or GPS charging in any weather!
• Built in protection turns off USB charging & prevents your parked vehicle’s LFP (LiFePO4) or AGM (Pb)battery from draining – Starts back up when vehicle engine fires up.
• Monitors and displays parked vehicle’s battery status – indicates battery is ‘start ready’ at the blink of an LED!
