The W050 takes the same magnetic wireless power bank concept as its siblings in Joyroom’s W-series and adds a built-in ring holder, which turns out to be a more useful addition than it might sound on paper. After using it for a while as my main travel backup charger, the ring holder ended up being the feature I reached for almost as often as the charging itself.

Core Specifications
The W050 packs a 10000mAh battery (rated 3.85V, 38.5Wh) into a slim housing with both wired and wireless charging output:
- 20W wired fast charging through its Type-C port.
- Up to 15W wireless charging output using Qi-compatible wireless charging standards.
- N52H-grade magnets for a strong, secure hold against compatible phones or magnetic ring cases.
- Simultaneous charging of up to three devices when combining the wired port, wireless pad, and a connected accessory.
- Price tier: mid-range magnetic power bank, priced above basic magnetic banks due to the added ring/kickstand hardware.
- Compatibility: natively magnetic phones (MagSafe-style), or any phone via a magnetic ring case adapter.
The Ring Holder in Daily Use
Unlike a plain magnetic power bank, the W050’s built-in ring gives you something to actually hold onto, which matters more than it seems once you are charging your phone one-handed while doing something else. It also folds out into a kickstand, propping the phone up at a comfortable angle for video calls or watching something while it charges on a desk or table.
- Doubles as a secure grip for one-handed phone use, reducing accidental drops.
- Functions as a kickstand for hands-free video viewing.
- Adds minimal extra bulk compared to power banks without any grip feature.
Charging Speed and Compatibility
Wired input and output specifications on the Type-C port cover 5V/3A, 9V/2A, and 12V/1.5A profiles, negotiating automatically with most modern phones to find the fastest supported speed. Wireless output tops out at 15W but automatically steps down to 10W, 7.5W, or 5W depending on what the connected phone’s wireless charging chip actually supports, since not every phone accepts the full 15W wireless rate.
The magnetic attachment works natively with phones that already support magnetic wireless charging, and with any other phone through a magnetic ring case adapter, the same approach used across most magnetic power banks on the market today, not something unique to Joyroom.
Battery Indicator and Everyday Reliability
A five-LED indicator shows both remaining power bank charge and active wireless charging status at a glance, which is a small but genuinely convenient touch compared to power banks that only show charge level and leave you guessing whether wireless charging is actually active. Over repeated daily charge cycles, the N52H magnets held their strength consistently without the noticeable weakening some cheaper magnetic power banks develop after a few months of use.
Who Should Consider the W050
- Frequent travelers who want one accessory that charges the phone, holds it securely, and props it up, instead of packing a separate ring holder and charger.
- Anyone who regularly props their phone up for video calls or streaming and wants that functionality built into their backup charger.
- Buyers who already have a magnetic wireless phone or magnetic ring case and want to add power bank convenience without extra cables.
Full specifications, warranty terms, and current pricing are listed on Joyroom’s official W050 product page, and it is worth reading independent accessory review roundups if you are comparing it against other magnetic power banks with kickstand features before deciding.
Troubleshooting Charging and Magnetic Alignment Issues
- Wireless charging won’t start: check that the phone and power bank’s magnets are actually snapped into alignment — the coils need to sit centered, and even a slightly off-center magnetic hold can stop charging from starting at all.
- Charging stops and restarts intermittently: a phone case thicker than about 3mm, or one with metal components, can interfere with both the magnetic hold and the wireless charging signal; remove the case to test.
- Power bank gets warm and slows down: this is normal thermal throttling under wireless charging: switch to the wired Type-C port for faster, cooler charging if speed matters more than convenience.
- Ring holder feels loose after months of use: wipe the hinge area clean of pocket lint and dust, which can build up and make the fold-out mechanism feel less snug than when new.
If wireless charging still will not engage after cleaning both magnetic surfaces, the manual fallback is simple: connect the phone directly to the power bank’s Type-C port with a cable. Wired charging bypasses the magnetic alignment step entirely and still delivers the full 20W output.
Frequently Asked Questions
Does the ring holder rotate?
Yes, the ring folds out and rotates to allow both a secure one-handed grip and a stable kickstand angle for landscape or portrait viewing.
Will the W050 work with my phone if it is not magnetic?
You will need a thin magnetic ring case or adapter attached to your phone first, after which the W050’s magnets will hold securely the same way as on natively magnetic phones.
Can I use the W050 while it is charging from the wall?
Most magnetic power banks in this category support limited pass-through charging, but for battery longevity it is generally better to fully charge the unit first before using it to charge a phone.
How long does the W050 last on a single charge for daily use?
At 10000mAh capacity, expect roughly one and a half to two full phone charges depending on your phone’s battery size and whether you use wired or the slightly less efficient wireless mode.
Cleaning and Long-Term Magnet Care
To keep the magnetic hold strong over months of use, wipe both the power bank’s magnetic face and the back of your phone or case periodically with a dry microfiber cloth. Dust, pocket lint, and skin oils gradually build up on both magnetic surfaces and can noticeably reduce how securely the two pieces snap together, even though the magnets themselves are not actually weakening. If you ever notice the connection feeling looser than when the unit was new, cleaning both surfaces before assuming the magnets have degraded usually solves the problem.
Packaging and Included Accessories
The W050 typically ships with the power bank itself and a short USB-C charging cable, without a separate wall adapter, consistent with most power banks at this price tier. If your phone does not already support magnetic wireless charging natively, check whether a magnetic ring case adapter is bundled with your specific regional listing, since some retailers include one while others sell it as a separate accessory.
Comparing the W050 to the Plain W020
If the ring holder and kickstand are not features you would actually use, the simpler W020 in Joyroom’s lineup covers similar wired and wireless charging specs at a lower price without the added grip mechanism. The W050 earns its slightly higher cost specifically for buyers who know they will use the stand function regularly, whether for video calls, watching content, or just wanting a steadier one-handed grip throughout the day.
Conclusion
The Joyroom W050 makes a strong case for itself by combining a competent 10000mAh magnetic wireless power bank with a genuinely useful ring holder and kickstand. It is a practical pick for anyone who wants fewer separate accessories cluttering a bag while still getting reliable charging speed and a secure grip.
