Buying Guides

ResMed and Philips CPAPs draw more than the spec sheet suggests. We measured overnight runtime to find stations that carry therapy through a full night.

Match battery capacity to real RV consumption. These expandable LiFePO4 systems make off-grid power practical from weekend trips to full time living.

The sub $300 class now includes LiFePO4 chemistry, pure sine wave output, and fast AC charging. We ranked the entry level units that actually deliver.

Manufacturers cut corners below $200 on cells, inverters, and ports. We bought and tested five budget units to separate the capable ones from the junk.

Field tested at campgrounds, dispersed sites, and alpine basecamps, these solar generators balance capacity and charging against the weight you carry.

Size home backup by daily watt-hours, then match peak versus continuous wattage. We compared stations that carry a fridge and lights through an outage.

Six units tested boondocking in desert heat, charging from alternators on mountain passes, and running 120V appliances in a real van electrical system.

Seven models tested under real campsite conditions to match capacity, weight, and recharge speed for phones, lights, and portable fridges off the grid.
