A few weekends ago, I decided to test out the BioLite Solar String Lights in my backyard during a bonfire with friends. I’d been wanting some outdoor lighting that didn’t require running a power cord or constantly changing batteries for use while camping. After a bit of searching, I landed on these lights and I’m glad I did. They totally delivered on everything I hoped for: easy to set up, long-lasting, and created just the right vibe.
First Look and Setup

Right out of the box, the BioLite Solar String Lights felt like solid quality. The 44-foot cord is nylon-braided, so it’s tangle-resistant and feels durable, not flimsy like some cheaper string lights I’ve come across. There are 20 small shatterproof bulbs spaced along the line, and the light they give off is warm and cozy, not blinding or harsh.
Setup was simple. I hung the lights between some trees around the fire pit. The built-in hook at the end made it easy to attach to just about anything. The detachable power unit, which includes the battery and solar panel, makes recharging a breeze. You can pop it off and charge it by sunlight or USB-C without taking down the whole string. It also doubles as a storage case for the lights, which makes packing and carrying them super convenient.
Lighting Vibes

The light is exactly what I was looking for. It gave off a soft glow that lit up the space enough to move around safely without overpowering the ambiance of the fire. Everyone commented on how good the setup looked and more than one person asked where I got them.
You can also switch between three lighting modes: low, medium, and high, depending on how bright you want it. I left mine on low and after leaving them hang outside for the weekend, the battery was not fully drained.
Biolite Solar String Lights Battery Life & Performance

One of the biggest selling points for me was the battery, and it didn’t disappoint. The built-in 4,000 mAh battery is rechargeable by solar panel or USB-C. I fully charged it before the weekend using USB-C, then let it do its thing.
It ran for two full nights on low mode without a problem. And even after being left out during a rainy Sunday, the lights worked perfectly on Monday night. With an IPX4 water-resistance rating, I felt confident they could handle the elements.
Multipurpose Ports

There are also a couple of handy ports built into the power pack:
- A USB-C input for fast charging
- A USB-A output so you can charge other devices (like your phone) from the light’s battery
This feature came in handy when I needed to charge my phone by the fire. We just plugged it into the string lights and got a little extra power. Totally unexpected, but super handy, especially since it kept the music going.
Size, Weight, and Portability

Weighing just over 26 ounces (745 g), this setup is surprisingly light considering everything it offers. The power pack is compact enough to easily stash in a backpack or cabinet when you’re not using it. It also comes with a handy adjustable loop, making it easy to hang from a backpack or hook. With 44 feet of cord, you’ve got plenty of length to light up a big area whether you’re stringing it across a campsite, around a tent, or on your backyard deck.

Have you tried using it during the winter? I wonder how it works in colder temps
Hi Kelsey, Biolite released this product last spring, so I haven’t had the opportunity to use the lights in winter yet. I have, however, used them in colder temperatures. For instance, while camping over Memorial Day weekend last spring, nighttime temperatures dipped into the 40s. The cold didn’t seem to affect their performance, and sunny daytime conditions allowed them to charge fully. In winter, cloud cover might make it more difficult for the lights to gain a full charge.
