If you have a modern caravan with a sophisticated 12V electrical system , their appeal may be somewhat reduced . If you get a larger unit of around 2000W capacity , it could be used as an alternative to a generator as a means to recharge your house batteries , remembering it will need to be recharged in a similar way to the caravan ’ s battery at some point .
It is worth considering these portable power stations can be used in a multitude of other environments . Since they retain their charge for long periods of time , they make excellent back-up household power supplies in the event of a long black-out .
If you can find multiple uses for a portable power station , their appeal and value increase substantially .
ISSUES TO CONSIDER
Like anything these days , with portable power stations , you get what you pay for . The biggest difference is the number of recharge cycles you can expect to get out of the internal battery . The lower-cost units will quote cycles in the hundreds , whereas the higher quality units will quote recharge cycles in the thousands .
While it is not always clear from the specifications , the reason for this is due to the different types of batteries used in these units .
