Helium for mac jayden6/13/2023 ![]() The temperature at which the liquid–gas phase change occurs. The temperature at which the solid–liquid phase change occurs. The arrangements of electrons above the last (closed shell) noble gas. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The atomic number of each element increases by one, reading from left to right.Įlements are organised into blocks by the orbital type in which the outer electrons are found. Members of a group typically have similar properties and electron configurations in their outer shell.Ī horizontal row in the periodic table. I prefer this approach, as I find the Helium’s cutouts make using the controls a bit of a hassle.A vertical column in the periodic table. While the Helium (like the Juice Pack Air for the iPhone 4 and 4S) uses cutouts around the iPhone’s buttons and controls, the new Juice Pack Air (like the old Juice Pack Plus) instead employs button overlays: Tiny buttons built into the case cover the volume and Sleep/Wake buttons, and a pass-through switch activates the phone’s Ring/Silent switch. Where the Juice Pack Air differs notably from the Helium is with the way it deals with the iPhone’s side-mounted controls. (The company says that charging the final 20 percent of the iPhone’s battery requires more power than increasing the phone’s battery by 20 percent at lower starting levels.) Unlike the Helium, the Juice Pack Air features pass-through button overlays for the iPhone 5’s switches and controls. To maximize battery life even more, the company suggests turning the case off again once your iPhone passes the 80 percent charged mark again. Mophie recommends turning on the case only after your iPhone’s built-in battery drops below 20 percent. The case powers your iPhone only when you flip the switch to on. Press the button, and the LEDs light up to indicate how full the battery is. On the back of the base sits a button, four LEDs, and a switch. And as with the Helium, the Air’s design leaves your iPhone’s headphone jack deeply recessed-while thin plugs like the one on Apple’s stock EarPods will fit through the case’s opening, the larger plugs on some third-party headphones will require the use of the included adapter. The base of the Juice Pack Air is very similar to that of the Helium: The Micro-USB port at the bottom (which can charge both the case and an iPhone 5 inside the case) is surrounded by a metal plate, suggesting that perhaps one day Mophie might release a contact charger for its cases. That’s two to three more hours than the Helium offers. Mophie says that the Air’s battery should add up to an additional eight hours of talk time eight hours of 3G or LTE Internet use or ten hours of Wi-Fi internet use. The biggest size difference is that the Air is just over 0.1 inches wider, and even there the difference is barely noticeable.īut with that slightly bigger size comes serious battery power. Still, while Mophie praised the Juice Pack Helium for that case’s slim profile, the Air isn’t much larger. As those measurements should indicate, the case does add a noticeable amount of bulk to the iPhone 5: A Juice Pack Air-clad iPhone 5 is nearly 0.7 inch taller than, and twice as thick as, the bare iPhone. The Juice Pack Air weighs 2.7 ounces and measures roughly 5.5 inches tall, 2.6 inches wide, and 0.6 inches thick. ![]() Two tiny pins in the lower portion of the case connect it to the battery housed in the larger piece. The smaller piece plugs into your iPhone 5’s Lightning port, while the longer piece covers the rest of your iPhone. Like the Helium, the new Juice Pack Air is split into two pieces.
