BALDR 330 Portable Power Station Features and Specifications

BALDR 330 is a rather compact and lightweight unit, considering its output power, energy stored and all the features it packs - its physical dimensions are (L x W x H) 8 x 6 x 6.5 inches (~20.3 x 15.3 x 16.5 cm) and it weighs 7.6 pounds (~3.45 kg).

The unit appears rather boxy - the top of the unit includes a foldable handle and 5W wireless charger, while the front panel includes 2W LED light, LCD display, control buttons, and input/output ports.

Edges of the body are made of rubberized plastic and can absorb the mechanical impacts rather well - this is an excellent feature, but don't abuse it :)

The foldable handle allows the user to carry the unit to shorter distances, while its dimensions allow the user to carry it easily in the backpack, although its 7.6 pounds will no go unnoticed, especially to longer distances.


Energy is stored using 18650 lithium-ion batteries, with a total of 297 Wh (82.5 Ah, 3.6 V) of stored energy.

The life expectancy of the batteries is ~500 cycles with the capacity drop to ~85% of the nominal capacity, although this depends on the BALDR 330 type of use (how quickly the batteries are being discharged), unit's care, local temperature, and similar.

Lithium-ion batteries feature a relatively small self-discharge rate, but nonetheless, it is recommended to recharge the stored unit every 3 months - this ensures that if the unit is required in an emergency, it will be 'almost' fully charged and ready to use.

BALDR 330 is rated at 330 watts (hence the '330' is part of the label), with the surge power of 700 watts.

Output ports include one 110V AC port (110V ±10%, 60Hz, pure sine wave form with 3% THD max.), one USB-C port, three USB QC3.0 ports, two 12V 5A DC ports, and one 12V 10A cigarette lighter port.

Thanks to the (almost) pure sine wave form of its AC port, BALDR 330 is able to power sensitive electronics, including laptops, TVs, gaming stations, and similar - for example, it can power 60W TV for up to 4 hours. baldr 330 power station 2
