- Price Value: At $79.99, the unit is $43.00 more than a $36.99 10W OontZ Angle 3 Shower Plus, trading higher rated power and extra features for a higher price.
Choose the Unbranded E86 when you need louder, bass-forward portable sound for outdoor gatherings, poolside use with IPX7 protection, or long low-volume endurance with USB power-out for device charging. Choose the Unbranded Portable Bluetooth Speaker when the combination of Bluetooth 5.0 range, TWS pairing to create wider stereo, dual passive radiators and included aux cable aligns with your use case. Skip the reviewed Unbranded E86 portable Bluetooth speaker if you require published dimensions, weight, battery capacity, charging-time details, charging port type or formal warranty terms before buying.
Compared to the OontZ Angle 3 Shower Plus Edition at $36.99, the price difference is $43.00 while the E86 offers 40W RMS versus the OontZ’s listed 10W output, TWS pairing and USB power-out.

Strengths & Weaknesses
The Unbranded E86 Portable Bluetooth Speaker is a 40W (60W peak) IPX7-rated portable unit aimed at outdoor use. The Unbranded E86 combines long runtime claims, a subwoofer/passive-radiator design, and Bluetooth 5.0 for mobile connectivity.
What We Like
High continuous output (40W RMS)
The Unbranded Portable Bluetooth Speaker lists a nominal 40W RMS and 60W peak output. 40W RMS gives louder sustained volume and more headroom than many 10–20W portables, improving outdoor sound fill. Hosts for pool parties and small outdoor gatherings who need higher SPL for background music are the primary beneficiaries.
IPX7 waterproofing with float capability
The E86 Portable Bluetooth Speaker carries an IPX7 rating and can float, submersible to 3.3 ft for 30 minutes when sealed. IPX7 allows safer use at pools and beaches compared with splash-only models, reducing water-damage risk for devices. Swimmers and campsite users who plan near-water playback will benefit from this level of ingress protection.
Long claimed battery life plus USB power-out
The E86 promises up to 32 hours of playtime at low volume and includes a USB output to charge devices on the go. Long runtime helps full-day excursions and the USB power-out functions as a simple power bank for phones. Campers and long travellers on multi-day trips benefit from extended runtime and the power-bank capability.
Multi-driver array and passive radiators for bass
Portable Bluetooth Speaker (IPX7, 40W, subwoofer) uses two 15W full-range drivers and two 5W tweeters. The driver array plus two passive radiators supports stronger low-frequency output and tighter bass response than single-driver designs. Listeners who prioritize deep bass for electronic or hip-hop music and patio users will gain most.
Bluetooth 5.0 and TWS stereo pairing
This E86 portable Bluetooth speaker (IPX7, Bluetooth 5.0) supports Bluetooth 5.0 with about 66 ft range, lower power draw, and TWS pairing. Bluetooth 5.0 improves connection stability and lowers latency versus older versions for phones and tablets during video or gaming. Users wanting dual-speaker stereo or stable streaming at outdoor distances benefit from these wireless features.
Practical accessories and robust housing
The reviewed Unbranded E86 portable Bluetooth speaker ships with a charging cable, 3.5mm aux cable, and a user guide in the box. ABS and metal housing with a built-in handle aid durability, resist light drops, and ease transport compared to fabric-wrapped designs. Outdoor users and those who carry speakers on trips will appreciate the tougher enclosure and included cables for quick setup.
Potential Drawbacks
Playtime specification applies only at low volume
The Unbranded E86 lists up to 32 hours of playtime, but specifies this duration occurs at low volume. Real-world runtime will be significantly shorter at moderate to high volume depending on listening level, reducing all-day use expectations. Day trippers and party hosts who play loud music should plan for shorter battery life.
Waterproofing depends on correct port sealing
The Unbranded Portable Bluetooth Speaker requires sealing the silicone flap over charging and aux ports to maintain IPX7 waterproofing. If users leave flaps open, ports become vulnerable to water and damage, defeating the submersion rating. Casual pool users and beachgoers who may forget to seal ports face higher risk of malfunction.
Peak versus RMS power can affect loudness expectations
The E86 Portable Bluetooth Speaker lists both 40W RMS and 60W peak power, which highlights instantaneous versus continuous output. Peak figures can overstate perceived loudness compared with RMS, complicating direct loudness comparisons with competitors. Buyers comparing models for outdoor loudness should prioritise RMS and on-site listening tests.
Limited technical documentation and missing measurements
Data regarding warranty terms, battery capacity (mAh), charging time and charging-port type was not available at the time of this review. Current specifications also omit product dimensions, weight and laboratory SPL/frequency-response figures, which limits direct performance comparisons. Shoppers needing exact travel weight, charge schedules, or verified loudness numbers should consider this documentation gap before purchase.

OVERALL VALUE VERDICT
Unbranded E86 Portable Bluetooth Speaker sells for $79.99, delivers 40W RMS (60W peak), has IPX7 waterproofing, and claims up to 32 hours playtime. Setup is simple via Bluetooth 5.0 pairing, and sealing the silicone flap preserves the IPX7 rating. The core strength is loud output and deep bass from two 15W full-range drivers, two 5W tweeters, and dual passive radiators. Data regarding warranty and charging port type was not available at the time of this review. At $79.99, Unbranded E86 undercuts many 40W party speakers while costing more than the OontZ Angle 3 at $36.99.
Buy If You…
This product excels in three specific scenarios:
- If you host pool parties with music spread over 30 feet, you need powerful outdoor output. Unbranded E86 provides 40W RMS and passive radiators for stronger bass and louder volume. This avoids renting a PA system or hiring sound gear that can cost $50+ per event.
- If you spend full weekends camping and need multi-day runtime without outlets, battery life matters. Unbranded Portable Bluetooth Speaker offers up to 32 hours at low volume and a USB power-out to charge phones. This reduces the need to buy a separate 10,000 mAh power bank costing around $20.
- If you want stereo coverage across a backyard near 400 square feet, true left-right imaging helps. E86 Portable Bluetooth Speaker supports TWS pairing of two units for up to 80W combined stereo. This saves buying a standalone stereo set that often costs $200+ for comparable loudness.
Skip If You…
Two deal-breakers make this the wrong choice:
- If you need a proven compact shower speaker under $40, portability and price matter more than raw power. Consider OontZ Angle 3 Shower Plus Edition at $36.99. That model offers a smaller 10W unit with a documented 2500 mAh battery and established user reviews.
- If you require a well-documented brand warranty and broad service networks for replacements or repairs, brand support matters. Consider JBL Flip 5 (~$100). The JBL Flip 5 provides clearer brand support and established repair pathways through many retailers.
Value Calculation
At $79.99, the Unbranded E86 delivers 40W RMS, which equals about $2.00 per watt. By comparison, the OontZ Angle 3 at $36.99 and 10W equals about $3.70 per watt, so the E86 offers more raw wattage value for the dollar.

FINAL VERDICT
Unbranded E86 Portable Bluetooth Speaker suits buyers who want 40W party sound, IPX7 floatability, and up to 32 hours runtime for pool or backyard use. The reviewed Unbranded E86 portable Bluetooth speaker delivers stronger bass and USB power-out for charging phones on day trips. Avoid Unbranded E86 if you prioritize documented warranty terms or established brand service networks. The core trade-off is choosing louder 40W value versus cheaper, smaller 10W alternatives.
Technical Terms Explained
To help you make the most informed decision, here are clear explanations of the technical terms used in this guide:
- IPX7
- A waterproof rating meaning the E86 can be submerged up to about 1 meter (≈3.3 ft) for 30 minutes when the port covers are properly sealed.
- RMS (watts)
- The continuous audio power the speaker can deliver – 40W RMS indicates the E86 can sustain roughly 40 watts of output for steady loudness without relying on short power spikes.
- Peak power
- A short-duration maximum power figure (60W peak for the E86) that describes brief bursts of extra loudness, not the speaker’s sustained output.
- TWS (True Wireless Stereo)
- A feature that wirelessly links two E86 units so one reproduces the left channel and the other the right, creating true left-right stereo without cables.
- Bluetooth 5.0
- The wireless protocol the E86 uses for audio streaming, providing improved range and connection stability (the review cites about 66 ft line-of-sight) compared with older Bluetooth versions.
- Passive radiator
- A non-powered diaphragm included in the E86’s enclosure that moves with internal air pressure to boost low-frequency bass response without adding another powered driver.
- SPL (Sound Pressure Level)
- A measure of how loud the speaker plays in decibels; the review notes the manufacturer did not provide SPL measurements for the E86, so exact dB loudness is unknown.
- USB power-out (power bank)
- A USB port on the E86 that can supply charge to phones or other devices from the speaker’s battery, though the review did not list the port type, output current, or battery capacity.
