The Voltaic Fuse 6W is a charge kit that includes a solar panel, a large zippered pouch, and a 4,000mAh external battery. Much like the Voltaic Arc 20W, the system is meant to be used together, meaning the battery pack charges off of the panel. However, unlike the Arc 20, the Fuse's battery pack can also be charged using a wall charger, making it a bit more versatile. The Fuse was efficient to charge its small battery and was able to charge our small electronics with ease. The downside to the Fuse is that it only charges one device at a time and the unit itself is relatively bulky, considering the actual capacity of the panel and the small size of the battery pack.

|Pros||Large storage compartment, compact, sleek battery pack, fairly efficient charging||Inexpensive, efficient, user-friendly, excels in partly cloudy conditions||Relatively lightweight for panel type, inexpensive, charges devices efficiently||Powerful, works well in partial sun, cheaper than other laptop compatible options||Efficient for its size, durable, rigid design makes it easy to prop up, designed and built in the US|
|Cons||Kit is bulky and difficult to attach to backpack, expensive||Bulky, heaviest weight||Ineffective if relying only on solar for power, less durable than other battery packs||Bulky, heavy, hard to set up, complicated adapters for laptop charge||Expensive, large, hard to transport, lacks storage pocket|
|Bottom Line||A large panel kit that has plenty of storage and attachment options.||We were impressed by the BigBlue's ability to charge our gadgets quickly and reliably; its reasonable price is the cherry on top.||An efficient, compact battery pack with a 2W solar charger on it; out of the panels of this style, the Renogy is a top performer.||The X-Dragon 40W is the largest panel we tested and works relatively well for charging a laptop, though it is cumbersome and heavy.||For a rigid, efficient panel that is well-made and reliable, look no further than the 14W from Suntactics.|

Our Analysis and Test Results
Charge Interruption Recovery
Smaller capacity panels typically have a hard time recovering charge after an interruption, and the Fuse 6W is no exception. On partially cloudy days, or in instances when the panel accidentally gets shaded for some time, the Voltaic's charging speed drops significantly. Much like the Renogy E.Flex 5W, the Fuse's charging speed slowed significantly after being shaded for only a few seconds. This fact is to be expected, as panels with more surface area can continue charging in variable conditions better than these smaller sized panels.
In terms of charging speed, the Fuse performed as well as the Renogy E.Flex 5W and charged our phone 26% over a half hour. We typically plugged our phone into the battery pack while trickle charging the battery off of the solar panel. With this set up, it took about four hours to completely charge our Pixel 3.
The solar panel charged the 4,000 mAh battery with ease as well. When plugged into the unit in full sun, the battery charged one out of three LED lights in one hour. With these charge times, the Fuse is on par with the other top-performing small capacity panels in this review.
Multiple Device Charging Speed
Here, the Fuse falls short, since the battery pack can't charge multiple devices at once, as there is only one USB port on the battery. If you use it for backpacking, road trips, or cycling trips, then perhaps charging one device at a time is sufficient. If you'd rather take a different route, check out one of the other battery pack/panels in this review, like the Renogy 15,000mAh.
The outside of the Fuse panel kit is a durable canvas material. This material protects the contents of the pouch, like the battery pack and any extra cords you may have. We liked this feature since many of the other panels in this review have smaller pockets that either do not have the same capacity or don't provide the same level of protection as the Fuse. We had no problems with the panel itself or the battery during our three month test period, making the Fuse a good choice in terms of durability.
Weight and Portability
Though durable, efficient, and easy-to-use, the Fuse is not necessarily the lightest or most portable panel we've tested. The battery pack is quite small, but the panel and pouch are large. This kit is similar in size and weight to many of the larger-capacity units but has less output power. The kit weighs 25.5 ounces, which is only one ounce less than our Editors' Choice winner, the BigBlue 28W. Other panels in the same weight range are the Voltaic Arc 20 and the RavPower 24W.
This panel kit is best in situations where its clip-in points and attachment set-up are applicable. Bike-packing or backpacking are ideal situations for this panel since the straps can help attach it to a backpack or pannier (it took us a little while to get our attachment system figured out). Ideally, we would recommend double-checking to make sure yours is compatible before buying this kit. Shown below are two different packs with which we tested this panel. The pack on the right ended up working way better with the Fuse.
Like the Voltaic Arc 20, the Fuse isn't as friendly on our wallets as others. The user-friendly design of the kit makes it more expensive than a basic fold-out panel, but this ease-of-use is not necessarily worth the extra dough. Sold for $99 online, the Fuse is one of the more expensive kits in this review, especially when considering the relatively low wattage of the panel.
We liked using the Voltaic Fuse 6W kit in specific situations. The extra straps and heavy-duty design of the pouch make it great for attaching to a backpack, but also add extra bulk when used in other scenarios. The battery charged our devices efficiently and is small and compact; the panel itself also has a small capacity but is surprisingly quick to charge. The Fuse is an investment, but if it seems suitable for your applications, it could be a good one.
