4 Solar Power Bank Lost Strap of 2026 Top Picks for Outdoor Carry

The Bone Power Strap is a silicone mounting accessory - not a power bank or charger - designed to hold a portable charger on your bicycle alongside a Bone Collection bike phone mount. It's best suited for cyclists, bike commuters, and touring riders who want to keep a power bank accessible on their handlebars so they can charge a phone while riding. This product does not store energy, charge devices, or include any electronics; it is purely a physical mounting strap made from silicone.

The Power Strap's primary function is to secure a portable charger to your bike using an anti-slip X-shaped strap design. The manufacturer lists compatibility with power banks that have a perimeter between 13cm and 18cm, which covers a fairly broad range of compact and mid-sized portable chargers. The X-shaped design allows you to orient the power bank either horizontally or vertically, which can be helpful when routing a charging cable to a phone mounted above or beside it. Because this is an accessory strap and not a charger, it has no ports, no battery capacity, no charging output, and no electrical specifications.

Bone manufactures the Power Strap from premium silicone, which the product description highlights as scratch-free, stain-resistant, and washable. The silicone material should grip a power bank's surface without marring it, and the stretchable construction accommodates different charger shapes within the listed perimeter range. At approximately 3.5 x 0.6 x 7.3 inches and roughly 0.03 pounds, the strap itself adds virtually no weight or bulk to a cycling setup. The black colorway should blend inconspicuously with most bike accessories.

Setup appears straightforward based on the product description. The strap is designed for quick assembly and disassembly, so riders can attach a power bank before a ride and remove it afterward without tools. However, this strap requires a compatible Bone Collection mount to function - specifically the Bike Tie or Bike Tie Pro Series. Users who don't already own one of these mounts will need to purchase one separately. The power bank itself and any charging cables are also not included.

The most significant limitation of the Bone Power Strap is its dependency on the Bone Collection ecosystem. Riders who use phone mounts from other brands cannot use this strap as a standalone accessory. Additionally, silicone strap retention may not match the security of a rigid clamp or bolted mount, which could be a concern on rough trails or bumpy roads. Users riding on smooth pavement for commuting purposes will likely find the silicone grip adequate, but those tackling mountain biking or gravel roads should consider whether a flexible strap provides enough hold for their power bank's weight.

The Bone Power Strap is a practical, affordable accessory for cyclists who already use or plan to buy a Bone Collection Bike Tie or Bike Tie Pro Series phone mount and want an integrated way to keep a portable charger mounted on their bike. It's a strong fit for bike commuters who rely on phone navigation and need to top off battery life during longer rides. Users who need a power bank, a phone mount, or a complete charging solution should look elsewhere - this is strictly a mounting strap. The strongest reason to choose it is the universal fit and scratch-free silicone design that lets you pair your preferred portable charger with your Bone bike mount without damaging either product.

The Bone Power Strap is designed exclusively for use with Bone Collection's Bike Tie and Bike Tie Pro Series bike phone mounts. It is not compatible with phone mounts from other manufacturers. Before purchasing, confirm that you own or plan to purchase one of these specific Bone Collection mounts.

For power bank compatibility, the manufacturer lists a perimeter range of 13cm to 18cm. This means the strap's stretchable silicone can wrap around power banks whose total perimeter (the distance around the widest cross-section) falls within that range. Most compact and mid-sized portable chargers should fit, but very large high-capacity power banks or unusually shaped units may fall outside this range. Measuring your power bank's perimeter before purchasing is a practical step to confirm fit.

Bone constructs the Power Strap from silicone, which the manufacturer describes as scratch-free, stain-resistant, and washable. Silicone is a common choice for bike accessories because it resists UV degradation, maintains flexibility across a range of temperatures, and provides natural grip without adhesives. The anti-slip X-shaped design is intended to keep the power bank from shifting during rides.

At roughly 0.03 pounds, the strap is extremely lightweight and should not affect bike handling or add noticeable weight to the handlebar area. The listed dimensions of approximately 3.5 x 0.6 x 7.3 inches suggest a slim profile that won't create significant wind resistance or visual clutter on the bike. Cleaning is simple - the silicone material can be washed with water to remove dirt, sweat, or road grime accumulated during rides.

The CaSZLUTION Adjustable Power Bank Holder Strap Mount is a mounting accessory - not a power bank or charger itself - designed to secure a portable charger to tripods, backpack straps, VR headsets, fences, or your body. It is best suited for photographers, hikers, campers, content creators, VR users, and anyone who regularly uses a power bank outdoors or during professional work and wants hands-free access to their portable charger without stuffing it in a pocket or digging through a bag. This product does not store energy, charge devices, or include any cables or electronics. Its sole purpose is to hold and position your existing power bank where you need it.

The strap is adjustable to fit power banks with a circumference (girth) ranging from 5.9 to 10.5 inches, which the manufacturer states covers popular models including the Anker Prime 9600mAh, 20100mAh, 26250mAh, and 27650mAh, the Anker 737 24000mAh, and the Anker laptop power bank 25,000mAh. That range should accommodate many mainstream portable chargers, but buyers should measure the circumference of their specific power bank before purchasing. A flexible square buckle allows the strap position to be adjusted so that charging ports and connected cables remain accessible and unobstructed, which is a thoughtful design detail for users who want to charge a phone or camera while the power bank stays mounted.

Build quality centers on 900D encrypted nylon fabric paired with a 1.5mm thick PP (polypropylene) support board and silicone anti-slip hook-and-loop fastening. The manufacturer describes the structure as breathable, intended to reduce heat buildup and stuffiness during extended use. This matters because power banks can generate heat during charging, and a breathable mounting solution may help with airflow compared to keeping a power bank sealed inside a bag pocket. The overall dimensions are listed at approximately 16.2 x 5.8 cm, and the weight is listed at roughly 0.16 pounds, making the holder itself very lightweight and easy to pack.

Setup is straightforward: wrap the strap around your power bank, adjust the square buckle to position the strap away from ports and cables, and secure it with the hook-and-loop closure. The included square carabiner lets you clip the mounted power bank to a belt loop, backpack strap, tripod leg, or gear loop for quick access. For photographers, the ability to mount a power bank directly on a tripod leg keeps backup power close to a camera without extra cable clutter. VR users can attach a power bank to a headset strap to extend play sessions. Travelers and festival attendees can clip it to a bag for easy grab-and-go charging.

The most important limitation is that this is an accessory only. It does not include a power bank, cables, or any charging hardware. Buyers who need actual portable power should shop for a power bank separately and then consider this holder as a complementary accessory. Additionally, while the adjustable range is broad, power banks with unusual shapes, very rounded edges, or circumferences outside the 5.9 to 10.5 inch range may not fit securely. The product is categorized under camera and binocular straps, which reflects its mounting-accessory nature rather than a charging product.

For users who already own a compatible power bank and want a practical, lightweight way to keep it accessible during hikes, camping trips, photography sessions, VR gaming, or daily commutes, the CaSZLUTION holder strap offers a focused solution at a modest cost. It is not for shoppers looking for a power bank itself or an all-in-one charging kit. The strongest reason to consider it is the combination of wide power bank compatibility, adjustable port-clearance design, breathable construction, and the included carabiner, which together address the specific problem of hands-free power bank access during active or professional use.

The CaSZLUTION power bank holder strap is designed to fit power banks with a circumference (girth) between 5.9 and 10.5 inches. The manufacturer specifically lists compatibility with the Anker Prime 9600mAh, Anker Prime 20100mAh, Anker Prime 26250mAh, Anker Prime 27650mAh, the Anker 737 24000mAh, and the Anker laptop power bank 25,000mAh. Other mainstream portable chargers that fall within the stated circumference range may also fit, but buyers should measure their specific device before purchasing to confirm compatibility.

The adjustable square buckle is designed to let users reposition the strap to avoid blocking charging ports and cable connections. This means the holder can accommodate different port layouts across various power bank brands and models without interfering with active charging. For users who frequently charge a phone or camera while the power bank is mounted on a tripod, backpack strap, or body, this port-clearance feature is a practical consideration that separates this holder from simple elastic bands or generic pouches.

The CaSZLUTION holder strap measures approximately 16.2 x 5.8 cm and weighs roughly 0.16 pounds according to the product listing. That compact size and minimal weight mean the holder adds almost no bulk to a camera bag, backpack, or travel kit. It can be rolled or folded flat for storage when not in use, and the included square carabiner allows it to be clipped to the outside of a bag for quick access.

For travelers, hikers, and commuters who already carry a power bank, this holder occupies very little additional space. It may be especially useful for users who want to keep a power bank externally mounted on a backpack strap or belt loop rather than buried inside a bag, making it faster to connect a phone or other device for on-the-go charging without stopping to rummage through gear.

CaSZLUTION describes the holder as constructed from 900D encrypted nylon, which is a relatively dense and durable fabric grade commonly used in tactical and outdoor gear. The 1.5mm thick PP (polypropylene) support board provides structural rigidity to keep the power bank from shifting or sagging, while silicone anti-slip hook-and-loop fastening is intended to prevent the power bank from sliding out during movement.

The breathable design is a notable detail. Power banks can generate heat during active charging, and a holder that allows airflow may help reduce heat buildup compared to enclosed pouches or tight pockets. The manufacturer describes the construction as robust enough for daily, professional, and outdoor activities. No water resistance, dust resistance, or IP rating is listed, so users should take care in wet or dusty environments.

The Xxerciz Adjustable Shoulder Strap is a purpose-built carrying accessory tailored directly for the Anker SOLIX C300 and C300 DC portable power stations. For campers, field workers, emergency-prep organizers, and outdoor enthusiasts who rely on mobile power stations, this strap transforms a boxy, hand-carried battery pack into a practical shoulder-carried unit. It serves users who need to transport their power supply across campsites, tailgates, or outdoor workspaces while keeping their hands free for other gear.

While this product does not supply electrical power or contain internal circuitry, it directly enhances portable charging routines through thoughtful cable management. The shoulder strap incorporates a dedicated small storage pouch sized specifically for charging cables, power cords, or small adapters. Keeping your primary USB-C cable or charging adapter mounted directly onto the carrying harness reduces pack clutter and ensures your connection essentials are never left behind when traveling off-grid.

Build construction centers on heavy-duty 900D encrypted nylon webbing engineered to handle repeated outdoor use without fraying or stretching under heavy load. The connection points feature rugged metal swivel hooks designed to snap cleanly into the power station anchor points. To minimize carrying fatigue, the strap includes a wide, breathable padded section crafted to distribute the weight across your shoulder and prevent the fabric from digging into your neck.

Daily handling is straightforward thanks to an adjustable strap length ranging from 37 inches to 61 inches (94 to 155 cm). This wide sizing spectrum accommodates various body heights and enables both traditional one-shoulder hauling and diagonal cross-body carry. A specialized non-slip clasp system maintains tension, ensuring that the strap does not lengthen or slip loose unexpectedly as you walk with the weight of the power station.

The main limitation of this product is its specialized design scope. It is an aftermarket accessory rather than an independent charging unit, so it requires you already own an Anker SOLIX C300 or C300 DC power station. Furthermore, power stations from other brands or larger multi-kilowatt units lacking matching mounting hardware will not properly accommodate the hook spacing or load profile of this specific strap assembly.

This replacement carrying strap is an easy recommendation for Anker SOLIX C300 and C300 DC owners who take their portable power stations outdoors and desire comfortable hands-free movement. Users who keep their battery stations parked strictly on a garage workbench or office desk can manage fine with the built-in top handle, but outdoor adventurers and road trippers will appreciate the ergonomic shoulder padding and integrated cable storage.

The Xxerciz shoulder strap measures 61 inches in maximum extended length by 2.75 inches in width, offering broad surface coverage across the shoulder. The 900D encrypted nylon fabric provides substantial tensile strength while resisting outdoor abrasion from dirt, vehicle trunks, and rough camping gear.

Heavy metal swivel clasps allow 360-degree rotation to prevent the nylon strap from twisting during transport. The built-in shoulder pad features a breathable cloth underside that helps reduce heat buildup and moisture when hauling equipment in warm weather conditions.

The Nitze N22-C1 is a power bank mounting accessory, not a power bank or charger itself. It is a simple strap-and-buckle holder designed to attach a portable power bank to a camera cage, monitor cage, iPad cage, or smartphone cage. This product is best suited for content creators, videographers, photographers, and live streamers who rely on external battery packs to keep their rigs powered during shoots and need a clean, secure way to mount that power source directly to their equipment.

Because the N22-C1 is a mounting accessory, it has no battery capacity, charging output, ports, or charging protocols of its own. Its value lies entirely in how well it secures a power bank to your rig. The manufacturer lists compatibility with popular power bank brands such as Anker, iWALK, INIU, ROMOSS, and Miady, and states that the adjustable strap can accommodate all power banks on the market. The total strap length is 210 mm, which should fit most compact and mid-sized portable chargers, though users with unusually large or thick power banks should verify dimensions before purchasing.

Build-wise, the Nitze N22-C1 uses an adjustable securing strap with a fastening buckle to hold the power bank in place. It mounts to standard 1/4-inch threaded holes found on most camera cages, cheese plates, and similar rig accessories using two included 1/4-inch screws. The overall dimensions are listed at approximately 8.3 x 2.7 x 0.5 inches, and the unit weighs just 55 grams (about 0.12 pounds). That minimal weight means attaching this mount to a rig adds almost no additional heft, which matters for handheld or gimbal-mounted setups where every gram counts.

Setting up the N22-C1 involves threading the two 1/4-inch screws into the threaded holes on your cage or cheese plate, then wrapping the adjustable strap around your power bank and tightening the buckle. There is no quick-release mechanism, so installation requires a bit of manual screwing, and swapping between different mounting positions takes a moment. Once secured, the strap holds the power bank against the cage, keeping cables tidy and preventing the battery pack from swinging or detaching during use. For on-location shoots, travel videography, or live streaming rigs, this kind of organization can reduce cable tangles and make the overall setup more manageable.

The biggest limitation of the Nitze N22-C1 is that it relies on strap tension and a buckle to hold the power bank, which may not provide the same rock-solid security as a rigid clamp or dedicated battery plate. During aggressive handheld movement or if the strap is not tightened properly, there is some risk of the power bank shifting. Additionally, this product does not include any power bank, cable, or charging hardware, so it only solves the mounting problem. Users who need a power bank itself will need to purchase one separately.

The Nitze N22-C1 power bank strap mount is a practical, inexpensive accessory for content creators and videographers who already own a portable power bank and want a clean way to attach it to their camera or monitor rig. Its universal strap design, standard 1/4-inch mounting, and featherweight 55-gram build make it a sensible addition to most cage-based setups. Users who need a rigid, vibration-resistant mount for heavy power banks or extreme shooting conditions may want to explore more robust mounting solutions. For everyday video production, vlogging rigs, and on-location setups, however, this strap mount from Nitze offers a simple and affordable way to keep backup power within reach.

The Nitze N22-C1 is designed to work with any portable power bank that fits within its 210 mm adjustable strap. The manufacturer specifically lists compatibility with power banks from Anker, iWALK, INIU, ROMOSS, and Miady, though the adjustable design should accommodate most compact and mid-sized battery packs regardless of brand. Before purchasing, it is worth measuring your power bank's circumference to confirm it falls within the strap's adjustable range.

For mounting, the N22-C1 attaches to any cage or cheese plate that features standard 1/4-inch threaded holes. This includes most camera cages, monitor cages, iPad cages, and smartphone cages from brands like SmallRig, Tilta, and Nitze's own cage lineup. The two included 1/4-inch screws handle the attachment, so no proprietary hardware or adapters are needed.

At just 55 grams and approximate dimensions of 8.3 x 2.7 x 0.5 inches, the Nitze N22-C1 takes up very little space in a camera bag, gear pouch, or carry-on. It can easily be stored alongside other small rig accessories without adding meaningful weight or bulk to your kit.

For traveling videographers and content creators who shoot on location, the compact size means you can pack the strap mount and forget about it until you need to mount a power bank on set. Its simplicity also means there are no fragile parts to worry about during transit.

The Nitze N22-C1 features a strap-and-buckle design with an adjustment mechanism that allows the user to tighten or loosen the fit around different power bank sizes. The mounting base uses two 1/4-inch screw points for secure attachment to threaded cage or cheese plate surfaces. Nitze is a recognized brand in the camera rigging accessory space, and the N22-C1 follows their typical approach of functional, no-frills design at an accessible price point.

One consideration is that a strap-based mount inherently provides less rigidity than a machined aluminum clamp or battery plate. For static setups like tripod-mounted interviews or desk-based streaming rigs, the strap should be more than adequate. For aggressive handheld shooting or gimbal use, users should ensure the buckle is firmly tightened and periodically check that the power bank has not shifted.
