More Details
Main highlights
- 【HIGH CAPACITY WITH LONG RUNNING TIME】With a capacity of 7500mAh / 96Wh, iVolt Xtra gives your Thinkware dash cam 66% more power than iVolt mini and a long running time of up to 27 hours* while in Parking Mode. In Energy Saving Mode, the dash cam can be operational for up to 960 hours (40 days)* so that your dash cam doesn’t miss an incident while parked for long durations.
- 【FAST CHARGING】Despite having a higher capacity than iVolt mini, iVolt Xtra can be fully charged in as little as 50 mins thanks to the Fast Charging feature. The battery can also be fully charged in 90 minutes in regular charging mode without affecting the lifespan of the battery. The external battery recharges while you are driving and powers your dash cam when the car’s ignition is off.
- 【DISCLAIMER】Hardwiring Cable is a required accessory to install the iVolt Xtra External Battery. Sold separately.
- 【COMPATIBLE WITH ELECTRIC VEHICLES】iVolt Xtra External Battery can be safely hardwired into both electric and gasoline cars. However, it is not possible to hardwire BAB-95 in some electric vehicles like Teslas because they do not have a traditional fuse box.
- 【BATTERY AND HEAT PROTECTION】The battery is made from Lithium Iron Phosphate (LiFePo4), which is safer and more stable than lithium-ion, and has a lifespan that is 3 times longer than that of lithium-ion and nickel-based batteries. Thanks to PCM (Protection Circuit Module), the battery helps protect against unexpected situations like overcharge, over-discharge, sudden input voltage change, and low voltage.
