Connected: compatible with the free BlackVue Battery Manager app.


Simple or Hardwired Installation

Power Magic Ultra Battery supports two charging modes.

Simple installation:
Just plug the battery into the cigarette lighter socket of your vehicle.
Charging current: 5A – Charging time: approx. 80 minutes.

Hardwired installation: 
For fastest charging speed, connect the battery to the fuse panel.
Charging current: 9A – Charging time: approx. 40 minutes.

12V/24V compatibility and USB power outlet

12V and 24V compatibility means you can use the Ultra Battery in most individual and commercial vehicles.

With the 5V (max 2A) USB outlet, power your Wi-Fi hotspot for your Cloud dashcam or any accessory.

You can even add more than one expansion in sequence.



Is this battery different from a regular power bank?

Yes indeed! The Ultra Battery is made of Lithium Iron Phosphate cells (LiFePO4). Power banks designed as backup batteries for phones and portable electronic devices are usually of the Lithium-ion (Li-ion) or Lithium-polymer (LiPo) type. Those high-density batteries are not suitable for use in a closed parked vehicle (where temperature can reach high–and low–levels) as they risk causing fire or explosion. LiFePO4 batteries can sustain more extreme temperatures, more charge cycles and are also more environment-friendly.

I have this 10,000 mAh power bank that is much smaller than this 6,000 mAh battery. What gives? 

mAh can be misleading if we don’t consider voltage. Tip: think in terms of Watt-hours (Wh). Of course the type of battery should be taken into consideration: high power density batteries have higher capacity for a given volume. In other words, at same capacity, a Li-ion or LiPo battery will always be smaller than a LiFePO4 battery. Still, you should keep in mind that consumer electronics and car accessories assume different voltage values. The milliamp rating of power banks is usually based on a voltage of 3.7V. This means for a 10,000 mAh battery, the total capacity is 10,000mAh x 3.7V / 1,000 = 37Wh. By way of comparison, the Power Magic Ultra Battery has a capacity of 6,000mAh at 12.8V, which translates into 76.8Wh.

Can I use Power Magic Ultra Battery in a commercial truck (24V)?

Yes. B-124X is compatible with 12V and 24V systems unlike its predecessor B-124 (Both named Power Magic Ultra Battery). This site only sells the B-124X. If you have a doubt about which model you have, check the connectors at the back: only B-124X features a USB port.

Can I bring the Power Magic Ultra Battery on a plane?

Yes, in carry-on luggage, in theory. But since batteries can be sensitive items to bring on an airplane, check with your local operator to be on the safe side. According to the IATA (International Air Transport Association) spare batteries under 100Wh can be carried on a plane in a carry-on luggage–NOT in checked luggage–like most lithium batteries, without requiring the operator’s approval.
