Suoaki, a Japanese company, has released a semi-portable battery pack rated at 200,000 mAh or 720 Wh. With this battery, it should be capable of charging a laptop for 11 times or a Nintendo Switch for 36 times. This kind of battery pack could be needed for those who need to travel a long distance on car, work somewhere away from the power grid, somewhere with an intermittent power supply, or just ensure that there is some extra power at home or in a remote cottage where one might want to spend the coronavirus quarantine.

The Suoaki S670 is rated at 720 Wh (200,000 mAh), which is why it is a complete overkill. You can't travel on a plane with it, because the legal limit for a battery on an aircraft is 100 Wh, but for those who need charging when travelling by car, or working from an isolated location, this is meant to be a tool to use. To put the 720 Wh capacity into perspective, this is enough to charge a modern laptop for 11 – 13 times, or an iPad Pro for 15 times, or a Nintendo Switch for 36 times. As an added bonus, the battery has two LEDs (sorry, no RGB).

The Suoaki S670 device has four AC outlets, two DC power connectors, two USB 5V/3A Type-A connectors, two USB QC 3.0-compatible ports, one USB 15V/3A Type-C connector that supports a 45 W Power Delivery, and one cigar socket (13V/10A). The battery pack can output up to 500 W of power to multiple devices at once. As for charging, the S670 can use a car charging socket (which takes seven to eight hours) or an AC adapter (which takes five to six hours). As for dimensions and weight, the unit measures 170mm×350mm×235mm and weighs 7.85 kilograms.

Number of charges, according to the manufacturer.

The high-capacity battery pack integrates multiple batteries, it has a microcontroller unit (MCU) and a battery management system (BMS) to support overcharge, overload, overheat/uderheat, overvoltage, and short circuit protection.

The Suoaki S670 720 Wh battery pack is available now in Japan. The unit is available for ¥79,880.

    I assume this is for very special scenarios. I don't know where others live but I live in an area with sunlight. There's cheaper solutions for smaller battery packs that come with large 100W foldable solar panels that connect up to them. A buddy bought one for around $400.

    If you have the option of living in an area that gets sunlight (i.e. Earth), look into that.

    Something similar to the Yeti Goal Zero

    Obviously shop around, the prices vary greatly based off sale.

    For comparison, a typical Tesla Model 3 battery stores 80,500Wh.
    80.5 KWh / (.72 kwh * 108 hrs) ~= 120,750 hours of 13.7 years of Nintendo Switch time, rounding down.

    "one USB 15V/3A Type-C connector that supports a 45 W Power Delivery"

    How is this not able to output at least 20V/3A? Would've actually expected all the way up to 20V/5A, but as long as it's 20V, it can charge most USB-C laptops. 15V is really a disappointment.

    Not only that. Still a lot of laptop nowadays still not support USB C charging. Charging using AC outlet will result a lot of power loss because you'll convert DC-AC-DC. Its cylindrical DC connector output is 12V, 10A 🤦‍♂️. Most laptop require 19.5V, 2-3A.

    I hope the developers of this over sized Battery knew of the FAA 100 Wh battery limit as to the size of Lithium Ion Battery that you can bring onto Aircraft.

    They do.
    This is actually a pretty good company that makes good products. I bought their Truck Jump Starter, which is just under the flight limit. It's pretty portable, so it doubles as my portable power-bank. It has a small display which shows 1%-99% battery capacity, compass, has a light and torch.

    This seems more like a "work from the beach" tool.

    Goal Zero has a whole "Yeti" lineup of Li-ion battery packs, from 200 up to 3000 Wh.

    For a grand you can get an EGO Nexus PowerStation and run a good chunk of your home in silence, with swappable battery packs that can be charged off-hours using solar or other means. Price is just totally uncompetitive. It already includes two 7.5Ah (56V!) packs in the kit which is already over 100Wh more than this thing.
