Always On ModeBattery features an Always On mode activated with the power button. In Always On mode, the outputs will not shut off even if your device is drawing low or no power. Battery recovers into Always On mode when charged after a full discharge.

Power consumption in Always On mode is approximately 0.11W when connected to the USB port and 0.22W when connected to the high voltage (12, 16, 19, 24V) output.

What is USB-C Power Delivery?

From the Voltaic engineers...

USB-C Power Delivery: An Intro
USB-PD, or USB-C Power Delivery, is a new protocol specification that allows for faster and more flexible charging. It was developed concurrently with USB Type-C (USB-C) which is the physical connection, and it is a subset of the new USB 3.1 standards. What this means is that:

1. The USB-C connector is reversible, so you won't have to struggle with flipping the plug until it fits – similar to how the iPhone's lightning connector works
2. Devices no longer need a separate USB and power jack, as older computers often have
3. Devices can charge and discharge through the same port, meaning power direction is no longer fixed
4. And most importantly, devices charge much faster! Without USB-PD, the fastest rate for USB-C would be 15W, but with PD it can go up to 100W

.

How does USB-C Power Delivery Work?
The basic gist of how it works is that two USB-PD enabled devices negotiate a power contract, or a handshake, when they're plugged into each other. They discuss how much power the source can support, as well as how much power the device being charged can handle. The standard for USB-C devices without PD is 5V/3A, but the voltage is configurable depending on the device and can go as high as 20V/5A (with an EMCA cable). Then they settle on a compatible rate which both the supply and device support and the charging (or discharging) begins.

It's important to note that not all USB-C ports support USB-PD, nor will all USB-C devices charge with all USB-C chargers. Take a look at PCWorld's post ⁵ written three years ago to see someone's compatibility test; the key example here is that HP's Spectre X2 will only charge from its own charger. However, take a look at their sequel ⁶, and you can see that USB-C has since become a near-universal standard.

Compatibility

Smartphones:
Charges all USB Devices including all Apple, Android, Google, and Blackberry smartphones.
Tablets:
Charges all known tablets using the manufacturer's USB charging cable.
Digital Cameras:
Charges both DSLRs and point-and-shoot cameras that charge from USB. For DSLRs, an optional camera charger cradle that matches your camera battery (see Adapter Section ⁷) is required. Read our tutorial on solar camera charging ⁸.
Microcontrollers:
Compatible with most microcontrollers including Arduino and Raspberry Pi.
Laptops:
Charges most consumer grade laptops (15” or smaller) from one of our Standard ⁹ or Optional ¹⁰ Laptop Adapters.Note: Gaming laptops are not compatible with the V88 due to high power requirements that exceed the maximum output of the the battery.
USB-C Laptops: Compatible with all laptops that charge from USB Type C. Charge directly from the USB-C PD Output using a USB-C to USB-C laptop cable ¹¹ (not included).
Acer: Standard “E” or Standard “L” Adapter
Apple: For pre-Thunderbolt MacBooks, optional MagSafe 1 ¹² or Optional MagSafe 2 ¹³ Adapter. Read our guide to charging MacBooks for more information.
ASUS: Standard “C” Adapter or Optional 4.0 x 1.35 mm ¹⁴ Adapter
Dell: Standard DELL Adapter or Optional Dell 4.5 x 2.8 x 0.6 mm ¹⁵ Adapter
HP: Optional HP 7.4 x 5.0 x 0.6 mm ¹⁶ Adapter or Optional HP 4.5 x 2.8 x 0.6 mm ¹⁷ Adapter
Lenovo: Standard Lenovo Square Adapter, Standard “G” Adapter, Standard “K” Adapter, or Optional Lenovo Slim Tip Adapter ¹⁸
Microsoft: Optional Surface Pro / Book ¹⁹ Adapter or Optional Surface 2 ²⁰ Adapter
Samsung:Standard “H” Adapter or Standard “C” Adapter
Toshiba: Standard “G” Adapter, Standard “C” Adapter, or Optional “B” Adapter ²¹
For additional information, visit our Laptop Adapter Guide ²².
AA / AAA Chargers:
If your device (headlamp, flashlight, radio, etc.) uses rechargeable AA / AAA batteries, confirm the device can safely charge from a 2A power supply before charging from the V88's USB port. To ensure safe charging to your AA / AAA batteries, consider using our USB AA / AAA Charger ²³.
Medical Devices:
Not compatible with medical devices, including CPAP machines.
