TESTED: PRIMUS POR­TA­BLE POWER PACK

THE PRIMUS POR­TA­BLE POWER PACK IS AL­MOST THE IDEAL SO­LU­TION FOR THOSE WITH­OUT A DUAL-BAT­TERY SET-UP.

MY POR­TA­BLE fridge spends much of its time sit­ting in the back of my 4x4, but I oc­ca­sion­ally drag it out and throw it in the back of a test ve­hi­cle, which means I have to power it from said ve­hi­cle’s start­ing bat­tery. Of course, the is­sue here is that I run the risk of drain­ing the start­ing bat­tery, es­pe­cially if I leave the fridge on overnight.

I re­cently bought a 44Ah Primus Por­ta­ble Power Pack to over­come this dilemma. I now run the fridge off the start­ing bat­tery dur­ing the day (when the ve­hi­cle is run­ning) and swap over to the power pack at night.

In­side the Primus Por­ta­ble Power Pack’s tough ABS hous­ing are two 22Ah AGM bat­ter­ies. There are sev­eral power out­let op­tions in­clud­ing a 12V/15A cig­a­rette lighter socket, a 12V/15A heavy-duty merit socket and a 5V/2A USB port.

The power pack comes with 240V AC and 12V DC charg­ing ca­bles, and it has an An­der­son socket con­nec­tion for charg­ing via a so­lar panel (not supplied). It should be noted that the 12V DC in­put is only enough to trickle-charge the power pack, so you’ll need to find a 240V AC power source or use the An­der­son socket con­nec­tion to give it a proper top-up dur­ing the day.

Fea­tures in­clude a dig­i­tal volt­age/ am­per­age dis­play, a low bat­tery warn­ing (light and alarm), over­load pro­tec­tion with re­set­table cir­cuit breaker, and supplied 240V AC and 12V DC charg­ing ca­bles. Weigh­ing in at 16kg, you’d hardly de­scribe the Primus pack as light, but it’s rel­a­tively com­pact (330x310x290mm) and easy to ma­noeu­vre thanks to a sturdy fold-away carry han­dle.

If you don’t have a dual-bat­tery set-up in your ve­hi­cle, the Primus Por­ta­ble Power Pack could be the ideal power so­lu­tion. How­ever, the fact it doesn’t fully charge via its supplied 12V DC ca­ble is a bit of an in­con­ve­nience and some­thing to keep in mind. The Power Pack should be charged ev­ery three months when not in use to main­tain peak per­for­mance, and it’s cov­ered by a 12-month war­ranty.
