Power any device anytime, anywhere by using its own AC power adapter.

This power station comes with a super high capacity light weight rechargeable lithium ion battery ( 36V 8.4Ah or 300Wh) and a 30 power inverter that converts the battery power to a 110V AC power just like the power source in your office or home wall outlet. Just link the power inverter to the battery, then plug your device AC power adapter to the power inverter

Battery Features:

Small Size and Light Weight:

This battery weight is only around 5 pounds (same capacity Lead-Acid battery will be around 25pound).

Dimensions: 260 x 148 x 56 mm (or 10.2" x 6" x 2.2")

Lithium-ion battery vs. Lead Acid Battery

Using a Lithium-ion battery offers many advantages over older SLA (Sealed Lead Acid) battery because of Lithium-ion battery'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. This battery weight is only around 5 pounds . A same capacity Sealed Lead Acid battery may weigh around 30 pounds.)

Cycle Life
(Residual capacity over 5%)

500 ~700 times

150~300 times


Very stable and very little affection by output current

Suffer a big affection in by output current. Capacity will be much smaller than rated capacity when output current is large.

Depth Of Discharge (D.O.D.)


50% ~ 60%

Self discharge rate (per month)

1~1.5% (Capacity remains over 80% even the battery is idled for one year)

30% (Battery capacity drops near to zero if it is unused for 3 months)

Fast charge capability

Charge to full capacity in about 6 hours

It needs 8 ~ 12 hours to fully charge the battery

Upright position is necessary


Built-in safety protection function

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

Power Inverter Features:

This power inverter can convert DC power from a 36V battery ( Voltage range can be 30V ~ 45V) into 110V 60Hz AC power, which is similar to the power supplied from your home electrical outlets.

This inverter has small size:180 x 110 x 55mm ( or 7.2" x 4.3" x 2.2") , light weight: 0.95kg or 2.1 lb. It is very easy to carry.
Compared to the traditional inverters, which output in modified sine wave, AC power in pure sine wave is more similar to commercial power. The electronic appliances run cleaner, cooler, and quieter when running on pure sine power. As a result, pure sine inverters save energy costs and extend the life of appliances.

The pure sine inverter also reduces electronic interference, making it a better alternative for operating sensitive audio/video equipment and medical devices. Appliances with dimmers, speed controls, and certain battery chargers may require pure sine power to operate.

Pure Sine Inverters are designed to increase the efficiency and running time of electronic appliances and motors. Our Inverters operate at less than 35% of Total Harmonic Distortion (THD) on average and 85% efficiency across the line.
