The Jackery Experience: Why Our Jackery 300 Fell Short
I’ll try to keep my bias at bay here, but while I really wanted to love our Jackery Explorer 300, I just can’t recommend it to fellow campers. To be fair, the Jackery 300 belongs to a smaller capacity class than our new setup, and I suspect we simply received a defective unit. However, our user experience was incredibly frustrating.
The biggest issue we faced was significant passive power drain. Even when completely turned off and charging absolutely nothing, the unit would regularly lose 20% or more of its battery life overnight. There were multiple times we woke up to find it completely at 0%, forcing us to constantly charge it from our vehicle’s alternator while driving.
After sitting unused for a few winter months, the battery dropped to a hard 0% and refused to accept a charge entirely. We sent it back to Jackery under warranty, but they simply shipped the exact same faulty unit back to us. On top of that, keeping the built-in Bluetooth turned on caused a massive, noticeable drain on the battery. Because of this poor customer service experience, the Jackery has sat on our shelf ever since.
The Upgrade: Bluetti AC70 Solar Generator Review
With another multi-week camping trip around the American Southwest on the horizon, we decided it was time to upgrade. Costco was running a sale on an electric car cooler, and Bluetti simultaneously launched a sale on their portable solar generators.
We pulled the trigger on the Bluetti AC70. It features a 1,000-watt pure sine wave inverter paired with a 768Wh LiFePO4 battery pack. To keep it topped off, we bought the accompanying 200W folding solar panels, which pack down incredibly flat and slide perfectly into our car's packing layout.
After several weeks of constant field use, I am incredibly impressed. The AC70 features an excellent selection of ports, including two AC plugs, two USB-A ports, and two 100W USB-C Power Delivery ports. Those 100W ports are an absolute game-changer for content creators, charging my MacBook Pro at full speed without needing to turn on the power-hungry AC inverter.
My other favorite feature of this Bluetti is Pass-Through charging - meaning it will charge the battery unit while also powering your devices.

Charging the Bluetti AC70: Real-World Testing
The AC70 offers versatile charging profiles depending on whether you have access to shore power (AC) or are living strictly off the grid (DC).
1. AC Grid Charging (Wall Outlets & Car Inverters)
When plugged into a standard AC wall outlet, the Bluetti app lets you toggle between three distinct charging modes:
Silent Mode (~140 Watts): Slow but steady. The unit is completely whisper-quiet.
Standard Mode (~400 Watts): Fast, efficient everyday charging.
Turbo Mode (~900+ Watts): Mind-blowingly fast. This mode fires up the internal cooling fans, but compared to our old, noisy Jackery, the Bluetti remains remarkably quiet overall.
If you have a strong enough custom inverter installed in your vehicle (I recommend a 1,000-watt pure sine wave inverter or greater), you can easily utilize these fast AC speeds right from your dashboard while driving.
The Bluetti app handles these mode switches seamlessly. While we initially ran into server errors trying to register a brand-new cloud account in the field, Bluetti’s Offline Bluetooth Mode works flawlessly without cell service, allowing us to monitor our metrics deep in the desert. Unlike the Jackery, the Bluetti's Bluetooth module uses a completely negligible amount of power.
2. DC Charging (Car Cigarette Lighter & Solar Power)
When charging via our vehicle's 12V cigarette lighter port, the unit pulls a steady 110W. It’s a slower charge, but if you are driving between camp spots for more than an hour, it easily tops the battery off.
For solar charging with the Bluetti 200W panels, the highest real-world intake I’ve seen in the field is 150 Watts, with a daily average hovering around 140W. This is completely normal given atmospheric conditions and solar angle inefficiencies.
📌 Pro-Tip for Solar Camping: Do yourself a huge favor and buy a pair of 30-foot solar extension cables on Amazon. Bluetti uses standard, universal MC4 connectors, making it incredibly cheap to extend your line. A 30-foot run allows you to park your vehicle in the shade while chasing peak sunlight with your panels.
If we are heading out on a midday hike and our battery needs a top-off, we simply lock the folding panels safely to our roof rack and let them bake in the desert sun while we're gone.
Here's the Bluetti on silent charging mode. It all comes down to numbers. Obviously more wattage will charge your unit more however I didn't find that the charge times were prohibitive for our lifestyle on the road.
The Verdict: Why the Bluetti AC70 Wins for Car Campers
For our specific style of nomadic car camping, the Bluetti AC70 is the absolute sweet spot for size, footprint, and power. After leaving our Igloo cooler plugged into the battery overnight for over 12 hours without any charging input, we consistently wake up to find the Bluetti still sitting comfortably at 72% to 77% capacity. (Stay tuned for my upcoming, full standalone review of the Igloo ICF40 cooler!). To give you some number the Igloo ICF40 will intermittently draw 50-60W however it will do it for maybe ten minutes at a time (depending on ambient temperature). It's not a constant draw of 50 W, which is what I was worried about. In real world testing while we were driving from Utah to Las Vegas the cooler will draw 56W for a few minutes, then keep its temperature for at least 30-40 minutes before requiring power. We did find the cooler kinda sucks as a cooler (without plugged in power), but for some unexplainable reason it's incredibly efficient while plugged in.
If you camp in high-sun environments like the desert Southwest, a 200W solar panel setup is more than enough to stay completely self-sufficient. However, if your travels take you to northern latitudes like the Pacific Northwest or the ALCAN, you may want to look into over-specifying with 400W or 500W of panels to compensate for the lower sun angles and cloud cover.
If you don't drive long distances frequently to recharge via your alternator, pairing a larger capacity Bluetti unit with dedicated solar is going to be your best off-grid strategy. The small, rugged footprint of the AC70 fits perfectly right on top of our cooler, saving us precious cargo space inside our rig.
