While we love "boondocking" (camp with no hook-ups).... we still have a few items we need to keep charged in order play music or our GPS that we use riding our dirt bikes.
We've used a Schumacher "Instant Portable Power" unit for about 6 years. I can't count how many times we've used it over the years. It is a solid "work horse" and has never failed to perform. It's an impressive tool! We've used it for big jobs such as jump starting cars and filling tires to the proper air pressure...to small jobs such as charging phones and laptops.
Last summer, we were camping... and we ended up in a heat wave. It was over 100 degrees for 5 days straight, which is not typical summer camping weather for us! The power unit came to our rescue as we used it to operate a small fan inside our RV. Having air moving around the RV made a huge difference....!
We mainly use the Schumacher "Instant Portable Power" during our camping trips, however, we were so impressed with it....that we now have an additional one that remains in our truck for those rare yet surprising "just in case" moments.
Jim will charge the units about 3 times a year. Yep..... it's amazing how well it maintains a charge. Another great feature ... it comes with a sealed lead acid battery which allows for storage in any position.
In the end.... the Schumacher "Instant Portable Power" unit is hands down one of the best purchases that we have made over the years.
