NEWDERY for Samsung Galaxy S25 Ultra Battery Case 6.9",10000mAh Portable Power Bank with LED Display, Qi Wireless Charger & 20W USB C Fast Charging, Sync-Data Supported Black
Quick take
This NEWDERY battery case for the Galaxy S25 Ultra combines a 10,000mAh power bank with Qi wireless charging support, plus a built-in LED display to show remaining battery level. It is geared toward travelers and busy days where you want long-lasting backup power without removing the case. The main caveat is that it is a thick, heavier case, and some buyers report the charging experience (especially wireless behavior and button sensitivity) is not as seamless as they expected.
Pros and cons
Pros
- 10,000mAh built-in battery for day-long backup, with an LED digital battery level display.
- USB-C wired fast charging support (up to 20W output) with USB-C input and output for two-way charging.
- Qi wireless charging compatibility, plus the case can also be recharged wirelessly.
- Designed to retain key phone functions, including data transfer and Android Auto support.
Cons
- It adds noticeable bulk and weight, which may not feel pocket-friendly.
- Not water resistant, so it is not a great choice for wet or outdoor conditions.
- Charging controls and efficiency are mixed, with some buyers reporting accidental activation or wireless charging that can be less efficient or slower.
- Wireless charging behavior may require remembering to start/stop charging via the case button.
What buyers think
Buyer-review evidence is mixed but still gives a clear pattern on the most important day-to-day factors. Several buyers highlight that the extra 10,000mAh capacity meaningfully extends phone power for travel or busy days, and they like the LED charge readout because it reduces guesswork. Many also mention that the case feels sturdy and offers drop-oriented protection (raised edges and a hard-shell design). On the downside, some buyers report the case is bulky, and a few raise concerns about how the wireless charging mode works in practice (including whether it starts charging automatically, how efficiently it performs, or whether the power button is easy to press accidentally). Overall, the evidence supports it as a capable travel battery case, but one that may require you to manage charging settings or button use more actively than with simpler battery packs.
Design and charging features that matter
10,000mAh backup power with a visible LED level
The core value here is straightforward: a built-in 10,000mAh battery intended to keep your Galaxy S25 Ultra running through long outings. The integrated LED digital display is meant to show battery level clearly, so you can decide whether you need to charge now or can wait.
USB-C fast charging, with two-way capability
This model supports USB-C input and output (two-way charging) and is specified for up to 20W output. That matters because it lets the case act like a small power bank, not just a charger for the phone. In practical terms, you can use a USB-C cable to top up other accessories or devices directly from the case when you are on the go.
Qi wireless charging, including wireless recharge
The case supports Qi wireless charging for the phone and can also be recharged wirelessly (so you can “top up the power bank” on a compatible wireless charger pad). For buyers who rely on wireless charging in daily life, this can be convenient. The main watch-out from buyer feedback is that wireless charging behavior can be less automatic and less efficient than expected, depending on how you power it and how you manage the case button.
Preserves important phone functions
For a battery case, compatibility is a big deal. This one is designed to retain original port functions, including data transfer, Android Auto, and support for wired headsets. If you routinely use navigation in your car or wired audio, that reduces the need to remove the case during daily tasks.
Pros and cons in real terms
Who it is best for
- Travel and long-day users who want a single device that keeps the S25 Ultra powered and visible battery level at a glance.
- Buyers who prefer mixed charging (USB-C wired fast charging plus Qi wireless charging).
- People who want pass-through functionality like Android Auto and data transfer without removing the case.
Who should think twice
- Anyone who hates bulk, because this is described and reviewed as thick and heavy.
- Outdoor or wet-condition shoppers, since it is not water resistant.
- Buyers who expect “set it and forget it” wireless charging, because some users report the wireless charging experience and the power-button behavior can take getting used to.
Installation and day-to-day usability
Most buyers focus on convenience, but the usability details differ by charging method. Some users find the one-click power control intuitive for starting and stopping charging, while others mention the power button can be easy to press accidentally, leading to unwanted charging. If you are the type who prefers automatic behavior, you may want to factor that in. Also, while wired charging is positioned as fast and straightforward, buyer comments suggest wired performance is more predictable than wireless in day-to-day use.
Price and availability
It is typically positioned as a mid-range accessory at the time of listing, and availability can change. If you are comparing options, treat the price as a tradeoff between (1) the integrated case form factor, (2) 10,000mAh capacity, (3) Qi wireless support, and (4) whether you value the LED display and pass-through function retention.
Is it worth it? A practical verdict
The NEWDERY battery case is a good fit if you want a Galaxy S25 Ultra case that also functions as a 10,000mAh backup power solution, with an LED battery readout and both USB-C and Qi wireless charging compatibility. It is especially appealing for travel and busy days where you want fewer gadgets. However, if you are highly sensitive to bulk, you use wireless charging constantly and expect it to be fully automatic, or you need water resistance for outdoor use, you may find the tradeoffs frustrating. In that case, consider a simpler battery charger case that prioritizes either wired efficiency or strictly automatic wireless charging behavior.
