This DC UPS can provide Uninterrupted Power Supply at Multi User Selected Output Voltages: 12V/15V/16V/18V/19V/20V/24V. It is compatible with many laptops, CPAP machines and many other devices, It is backed up by a High Capacity LiFePO4 Battery (12.8V 20Ah or 256 Watt-hour).

This UPS system is very simple to use, just connect battery AC charger to a 100V ~ 240V Power source, DC converter to a device that runs from 12V to 24V DC power. The system can support uninterrupted DC power up to 90W continues output.

This UPS pack comes with a large capacity LiFePO4 battery (12.8V 20Ah or 256Wh), a DD90X DC converter that can convert battery output voltage to 12V/15V/16V/18V/19V/20V/24V DC power at your selection, compatible with many laptops and CPAP machines, with maximum output up to 90W. A Large AC Charger that can fully charge battery in less than 3 hours and can supply uninterrupted DC power up to 90W continues output.


DD90X DC to DC Converter :

DD90X Power converter can connect to battery with enclosed connection cable to provide regulated output voltage.

Battery Features:

High Capacity: This battery capacity is 256 Watt-hour( 12.8V 20Ah)

Light Weight: This battery only weighs 5.6 pounds.

This battery has two Input / Output connectors. You may use them to charge battery or get power from battery. One end is 5.5 x 2.5mm female connector with positive polarity ( Inside positive, outside negative/ground). Another end has two wires with Anderson Power Pole connector. Red Wire is positive, Black wire is negative/ground.

Lithium Iron Phosphate (LiFePO4)Pros:

Long life span (5-10 years) vs lead acid (1-3 years), depending on depth of discharge and assuming that the cycle limit doesn't kill the battery first Longer cycle life, as LiFePO4 batteries last 1,000 to 3,000 charge and discharge cycles, compared to similarly sized lead-acid batteries, which can range from 200 - 1000 cycles (again, assuming depth of discharge is within recommended limits for both battery types).

LiFePO4 batteries are less susceptible to problems caused by depth of discharge...a LiFePO4 battery can be dropped to 20% of charge without long-term damage. Most lead-acid batteries lose capacity or cycle life if they're discharged more than 50%.

Lighter than lead-acid batteries.

Arguably, LiFePO4 batteries are more environmentally friendly than lead acid.

Very safe - the odds of a "thermal runaway" (aka battery fire) are very low. The same can not be said of other lithium ion chemistry.

Powerful Battery Charger:

The package comes with a 10A AC charger, that can fully charge battery within 3 hours when battery is not in use. It can support uninterrupted DC power up to 90W continues output and still have plenty of power to charge the battery at same time.

Cautions: Please use the BiXPower authorized charger with correct setting to charge the battery only. Wrong chargers may damage the battery and can cause fire. This battery charging voltage is 14.4V ~ 14.6V.

This DC to DC power adapter can convert battery power to 12/15/16/18.5/19.5/24v voltage DC output power for laptop/notebook computers, tablet computers or other devices.

It can also provide 5V USB port power for smart phones such as iPhones (USB power cable not included)

This DC power adapter can accept 10V ~ 30V DC power, it can be used with many of our BiXPower 12V, 16V, 19V and 24V batteries.

Set DC Output Voltage

This adapter has an output voltage selection switch on side. Please refer to the electronic device you are powering to determine correct voltage. It should be marked on the DC input jack. You may also refer to the manual to determine the proper voltage setting. If there is a discrepancy between the battery chart and the setting marked on your electronic devices, ALWAYS select the voltage close to it. For example, if your laptop DC input requirement is 19.5V, you can set at 19V first, then if it does not work, set at 20V.

Caution: Please set the output voltage before connecting power adapter to input & output. If you need to change the output voltage, please disconnect the power adapter from both input & output first. Do not change the output voltage when the power adapter is connected to input power source or output device. If the power adapter stops working, disconnect it from both input and output and check if there is anything wrong with the connection.

  • If this battery is misused or abused, it can result in personal injury from heat, smoke, fire or explosion.
  • Obtain approval of airlines or courier companies before traveling with or shipping this battery pack.

    Charging: Only use the chargers supplied with the battery or BiXPower authorized chargers to charge the battery. Chargers with incorrect voltage, current, or polarity settings may damage the battery. Please monitor the charging process and react to potential problems that may occur. If you cannot, please make sure to leave it on an isolated fireproof area, away from other flammable materials.

    Storage & Handling: DO NOT leave a fully exhausted battery on a shelf. Charge it to least at 50% or more if you do not need to use it for a long time. Do not leave the battery dormant for long periods of time. We recommend using the battery at least once a month. If a battery has not been used for a long period of time, please perform the new battery exercise. Fully discharge and then fully charge the battery at least once every 3 months. Always store the battery in a cool and dry place between 0°C (32 F) and 20°C (70°F), and away from flammable materials.

    Fire/Smoke Emission: Batteries contain flammable/combustible material that can be ignited, explode, release toxic materials, cause burns or give off gases when heated or in contact with sparks or flames. In the event of fire, vapor releases, and/or smoke emissions, evacuate the immediate area of all unnecessary personnel.
