While it can’t power high-wattage appliances, its compact nature can still handle lower-power personal devices like a lightbulb, a laptop, and a box fan. And yes, that’s an “and,” not an “or.” You can power multiple devices simultaneously as long as it doesn’t exceed the RIVER 2’s operating AC output, which is 300W.

You don’t have to choose between charging your RIVER 2 and using it to charge other devices; it can handle both simultaneously. Power up using the sun while giving your devices the power they need.

Best for Dry Camping: RIVER 2 Max Solar Generator

If you’re dry camping or camping somewhere without access to water or electricity hookups, you may want to consider upgrading to something more substantial, like the RIVER 2 Max Solar Generator. With a much stronger AC output of 500W (or 1000W on X-Boost Mode), the RIVER 2 Max gives you enough power for larger devices and equipment, which will come in handy when you don’t have other access to electricity. You can use your generator to power items like a blender, a small Keurig, or even a small refrigerator, in addition to powering up your personal devices.

The RIVER 2 Max is still portable at just 13.4 pounds and won’t take up much room in your RV or campsite. When you need power fast, you’ll be glad that the RIVER 2 Max’s charging speed beats the industry standard, offering complete 0-100% charging in just one hour using the AC outlet or just 4 hours with pure solar charging.

Even after many camping trips, your RIVER 2 Max will still work great thanks to a long-lasting LiFePO4 battery that’s also dust- and water-resistant, so you won’t have to take the campsite dirt and grime home with you.

  • Heavier and bulkier, but still not enough power for larger appliances

Best for Extended Camping Trips: RIVER 2 Pro Solar Generator

If you’re planning an extended camping trip, the RIVER 2 Pro is your best bet. With a massive storage capacity and impressive AC output, the RIVER 2 Pro is a must-have for any long camping trip where you’ll want more of the comforts of home.

The RIVER 2 Pro is powerful enough to power high-wattage appliances like a space heater and hot plate, so you can enjoy all the niceties you’re used to even while off the grid. It’s also perfect for road trips since it’s still lightweight, but it’s likely not something you want to carry in your bag for long periods.

While the RIver 2 Pro is an investment, it will last – offering up to 10 years of use thanks to its LifePO4 battery.

And with reliability like less than a 30 ms switchover speed, you can use it as an emergency power supply to avoid any outages on your long camping trips.

If you’re hitting the road for a weekend getaway, the DELTA 2 Solar Generator is your perfect companion. It’s bigger than the RIVER 2 Pro, but it won’t take up too much room in your packed vehicle while on the road.

It has enough power to run most appliances and personal devices like laptops and phones. And then, when you set up for the night at a hotel or campsite, you can set up even bigger and more demanding appliances like a clothes iron, coffee maker, electric skillet, and more.

This solar generator has an impressive charging time of just 50 minutes on AC power to go from 0-80%, making it ideal for overnight trips.

The DELTA 2 Max Solar Generator is the perfect companion for weekend RV trips. It is slightly larger than the previous option, but finding a spot for it in an RV is easy. 

While its weight of 50.7 lbs might seem heavy, it’s still the industry’s highest option for a 2400W LFP Solar Generator. You won’t find anything more portable than this that offers the same power.

For weekend RV trips, you’ll need to use most of your typical devices and equipment, and thankfully, this solar generator can power up to 99% of appliances, including a refrigerator for up to 14 hours and a WiFi router for 97 hours (to name a few). And with the world’s fastest recharging speeds of just 43 minutes to 80% charge when you combine AC charging and up to 1000W solar input, you’ll almost always have access to this incredible power source.

You won’t be tied down by cables running from your camper either since the DELTA 2 Max can be used as a mobile power station with USB-C charging and other options like AC and DC outlets.

What to Look for When Buying a Solar Charger for Backpacking

To find the right power solution for you, considering your own needs and goals is crucial. You may not always need the biggest and most expensive option. Here are a few things to remember when buying a solar charger for an upcoming backpacking trip.

Power Output

The power output is the maximum amount of electricity your solar charger can provide. Consider how many devices you plan on charging and how much energy each requires. If you plan on using high-power devices such as laptops or mini-fridges, you must look for a charger with a higher power output.

Battery Capacity

The battery capacity is measured in watt-hours (Wh) and dictates how much energy can be stored until used. It’s essential to ensure that your generator has enough storage capacity to support the device you plan on using and its duration of use. To find the watt hours you require, multiply the watts of a device you need to use by the number of hours you’ll need to use it.


When backpacking, size matters! Look for a small, lightweight generator that won’t take up too much room in your pack if you plan to carry it. EcoFlow offers several solar generators with different size options to meet every need.

Recharge Time

Your solar charger’s recharge time should also be considered, as you don’t want to spend all day waiting for it to charge. EcoFlow generators offer some of the quickest charging times on the market.
