Yes, all EXCITRUS power banks can be taken on board airplanes.
According to ITAT requirement, all external batteries with a capacity lower than 100 watt hours can legally and safely be taken on board airplanes. To calculate an external battery's capacity in watt hours: (Battery mAh Capacity X 3.7/3.6)/1000. Here are the relevant requirements quoted from federal transportation security rules: Effective January 1, 2008: Passengers may carry consumer-sized lithium ion batteries (a.k.a. rechargeable lithium, lithium polymer, LIPO, secondary lithium) with no more than 8 grams of equivalent lithium content or 100 watt hours (wh) per battery. This size covers AA, AAA, 9-volt, cell phone, PDA, camera, camcorder, Gameboy, and standard laptop computer batteries. Passengers can also bring two (2) larger lithium ion batteries (more than 8 grams, up to 25 grams of equivalent lithium content per battery) in their carry-on. This size covers larger extended-life laptop batteries. Most consumer lithium ion batteries are below this size.
However, this issue of compatibility is about to be a thing of the past with the introduction of the USB Power Delivery Specification. USB Power Delivery (or PD, for short) is a single charging standard that can be used all across USB devices. Normally, each device charged by USB will have their own separate adapter, but not anymore. One universal USB PD will be able to power a wide variety of different devices.
The biggest advantage is that USB Power Delivery has increased standard power levels to up to 100W. This means your device will be able to charge much faster than before. Also, this will work for most devices and will be great for laptop users, Nintendo Switch users.
Another great feature of USB PD is Power delivery is a two-way street: One of the most exciting developments in recent USB technology is two-way charging. This means that, for example, your tablet could be used to power a portable hard drive via the charge port. This functionality unlocks bold new possibilities for consumers and manufacturers alike.
Power delivery doesn’t discriminate between devices. PD is backward compatible with devices designed for other USB standards, like 2.0, 3.0, and type-C. It intelligently delivers an appropriate amount of power based on the architecture of the device to which it is connected. Ensure devices are not overcharged and will only provide the necessary amount of juice needed. While most smart phones won’t be able to take advantage of the added power, many other devices and computers will be able to.
Gallium Nitride (GaN) is a semiconductor compound that is commonly used in Light Emitting Diodes (LEDs) and high-powered transistors that operate at high temperatures. The material can also be used in the production of semiconductor power devices, lasers, photonics, and radiofrequency (RF) components. It will also be integrated into sensor technology in the future. GaN is capable of displacing silicon semiconductors in power conversion RF and many analog applications.
GaN is an extremely hard binary III/V material that contains a Wurtzite crystal structure. The mechanically reliable wide bandgap compound contains high heat capacity and thermal conductivity. When it’s in its purest form, it can resist cracks and can be placed in a thin film on sapphire or silicon carbide, regardless of their lattice constants mismatch. GaN can also be doped with two types of elements, silicon or oxygen to n-type and with magnesium to p-type, but both silicon and magnesium atoms alter how GaN crystals grow. The compounds have the tendency to have a high dislocation density. GaN’s wide bandgap behavior is associated with certain changes in the electronic band structure, chemical bond regions, and charge occupation.
Some of the benefits in the GaN compound that can be used in devices generally include:
Lower energy costs: Less energy is expended as heat, which results in materials that are less costly and systems that can be scaled down in size. This is mainly due to the fact that GaN semiconductors are more efficient than silicon.
Power density is higher: Higher switching frequencies than silicon in addition to operational temperatures contribute to smaller heat sinks, lower cooling requirements, liquid-cooling to air cooling conversion, elimination of fans and a cut back on magnetics.
Less costly system: Even though GaN semiconductors are more expensive than silicon, the cost reduction is a result of smaller size/costs of other components such as filters, cooling, passive inductive and capacitive circuit elements.
Higher switching frequencies: Since GaN devices have higher switching frequencies, smaller inductors and capacitors can be used in power circuits. Both the inductance and capacitance are scaled down to match the frequency, where a 10x frequency increase produces a 10x decrease in the capacitance and inductance. As a result, the weight, cost, and volume are all significantly decreased. High frequency also has the potential to create less noise in motor drive applications.
Your new Excitrus power bank has been pre-charged to a low battery level due to transportation policies.
In order to have best charging experience, it is recommended to recharge the power bank fully before using it for the first time.
For the first recharging of your Excitrus power bank, please use a traditional USB-A charger, such as Quick Charge (QC) charger or common 5V charger and the provided USB-A to USB-C cable to fully recharge the power bank. (The USB-C end of the cable goes into the power bank’s USB-C port). After this initial charge, a USB-C Power Delivery (PD) charger will provide the quickest recharge time. However, a USB-A charger can always be used.
