Description
 
This power pack comes with a super high capacity light weight rechargeable lithium ion battery ( 36V 11.6Ah or 418Wh) and a 36V to 19V DC Converter that converts the battery power to 19V DC power, maximum output 10 Amps at 19 DC



Battery Features:

Small Size and Light Weight:

This battery weighs only around 5 pounds.

Lithium-ion battery vs. Lead Acid Battery

Using a Lithium-ion battery offers many advantages over older SLA (Sealed Lead Acid) batteries because of Lithium-ion's high energy density, small size, and low weight. A typical Lithium-ion battery may only be 1/5 of the weight and 1/2 of the size compared to a same capacity traditional heavy bulky Sealed Lead Acid batter.

Danger of acid leakage

Environmental conform-ability

Conforms to RoHs standard

Violates RoHs standard;Lead and sulphate acid are pollutants

Disposition of used battery

Lithium-ion batteries are generally not considered an environmental hazard because they do not contain lithium metal. The United States government labels them as non-hazardous waste and does not oppose them being discarded together with the trash that makes up the local waste stream.

Needs special recycling after treatment utility


LED Display:

The Four-level LED indicates current power status.


AC Charger:

This battery comes with its own AC charger that can charge the battery from any 110V ~ 240V AC power source.



Safety Features:
  • Water-resistant and firm ABS plastic casing.
  • Built-in PCB protection.
  • Prevent short circuit, over-current, over-heat, over-charge, over-discharge.
  • The internal pack is stabilized by braces, thereby avoiding mechanical accidents caused by vibration.

19V DC Converter Features:

This DC to DC power adapter can convert 36V DC (range 25-48V) to 19V DC power. Maximum output 10A (190W)

It can directly connect to a 36V lithium ion battery or any battery with output voltage range between 25V to 48V. Its maximum output is 10A (190W)




This DC to DC power adapter's input side has two 16AWG bare wires. The output is a 5.5 x 2.5mm male barrel connector with 16AWG wires. It is very easy and flexible to connect with batteries and other power source.

Features:
Wide input range: 25V ~ 48V
Large output: up to 190W
High efficiency ( > 90%)
Small size: 2.98 x 2.98 x 1.3 (74 x 74 x 32.5 mm)
Light weight:
10.2 oz (289g )
Water resistant design





Input:
The red color is for Positive input and the black color is for Negative/Ground input. It is CRITICAL that the power adapter is connected correctly in polarity to the power source: Positive on adapter connects to Positive on power source. Negative on adapter connects to Negative on power source. FAILURE TO DO SO MAY RESULT IN SEVERE DAMAGES.
Output: The output connector is a 5.5 x 2.5mm male barrel connector. This connector can only handle 10A current for a short period of time. It is recommended for use with a continuous current 6A ( 120W) or less. Most laptop computers that come with a 180W to 240W power adapter actually need less than 120W of power most of the time.

Technical Specifications:

  • Acceptable Input DC Voltage Range : 25V ~ 48V
  • Output power(max) 190W
  • Output voltage: 19V
  • Output current: Max. 10A*
  • Efficiency: > 90%
  • Safety Protections: Over Current & Over Voltage Protection
  • Short Circuit Protection: Yes
  • Weight 10.2 oz (289g )
  • Dimension 2.98 x 2.98 x 1.3 (74 x 74 x 32.5 mm)

*10A is its maximum output current, not actual output current. Actual output current depends on the device's requirements. For example, if your device requires 2 Amps, it will output 2 Amps.

Connector tips:




The connector on the power adapter output cable is a 5.5 x 2.5mm male barrel connector, which will work with many devices. If you need different size connectors, you may order our C series optional connector tips separately. A C series connector can plug on the battery output cable to form a new connector.
