CUKTECH 45W 20,000mAh Power Bank
Home/Universal/Power Banks/YELOMIN 38800mAh Solar Power Bank
Best understood as a $17.99 rugged camp battery with a flashlight and a carabiner. A working unit gives you a lot of USB power for the money and the shell survives a trip. The solar panel is a backup trickle, and the 38,800mAh label isn’t the real usable figure.

Version reviewed: YELOMIN 38800mAh Solar Power Bank, Portable Charger with USB-C, dual LED flashlight · ASIN B0FWCG53DH · Amazon US listing · no separate manufacturer model number is printed on the listing.
One-sentence verdict: Worth it as a large, cheap battery with a flashlight for camping or travel if you treat the solar panel as a backup trickle only — skip it if you expect to recharge it from the sun or the advertised capacity to be real.

Treat the solar panel as an emergency trickle, not a charging method.

A rugged plastic slab with a small solar cell on the face, two output ports, twin flashlights and a carabiner loop. It looks and feels built for a backpack, and the shell takes knocks. Nothing about the electronics is documented, and the capacity claim is inflated in the way this whole product segment inflates it.
Charge it fully from a wall adapter over USB-C before a trip — do not rely on the sun. Then plug in your devices.
For a power bank, performance is usable capacity, charge speed, heat, recharge time and — here — solar input. Usable capacity is materially below the label. Charge speed is basic. Solar input is a slow trickle at best and, by many owner accounts, effectively nothing. Recharge from a wall adapter takes several hours because the real battery is still large.
Works with:
Not compatible:
The shell is tough; the electronics are a lottery. Some units are fine for a long time, some arrive dead. There is no warranty and no meaningful brand support.
At $17.99 on Amazon (price checked Sep 17, 2026), it is priced as a big cheap battery, and on that basis it can be fine.
Judge it as a $17.99 USB battery with a flashlight, not as a 38,800mAh solar charger. If a working unit does 20,000–25,000mAh of real capacity, that is still reasonable value at the price. If you get a dead one, there is no recourse. We would call it a fair buy under about $15, with expectations set low.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| YELOMIN 38800mAh Solar Power Bank (this bank) | A big cheap camping battery with a flashlight | Lots of capacity for $17.99; rugged; flashlight | Inflated capacity; token solar; no warranty | $17.99 |
| Anker 10,000mAh 30W Power Bank | A smaller battery you can trust | Honest capacity, 30W, 18-month warranty | Less capacity; no flashlight or solar | $29.99 |
| UGREEN Nexode 20,000mAh 45W | Real high capacity with a display | Verified capacity, 45W, health readout | No flashlight; costs more | $34.98 |
If you want capacity you can trust, an Anker or UGREEN bank states honest numbers and carries a warranty. This YELOMIN is for people who want a cheap, big, rugged camp battery and treat the solar panel as decoration. Prices are Amazon figures from August 26, 2026.
The YELOMIN 38800mAh Solar Power Bank is best understood as a $17.99 rugged camp battery with a flashlight and a carabiner. On that basis, a working unit gives you a lot of USB power for the money, and the shell survives a trip.
Do not buy it for the two things in the name. The 38,800mAh is inflated — owner testing lands well below it — and the solar panel is a token trickle that many owners say does nothing useful. Reliability is a lottery with no warranty behind it. Its 3.0 score reflects a product that is fine as a cheap battery and misleading as a solar charger.

|---|---|
| Design — rugged, flashlight and carabiner; token solar cell | 3.5 / 5 |

This is a low-information listing. “N/A” means the value is not stated. Owner testing suggests the real usable capacity is well below the advertised 38,800mAh.
Not practically. The onboard panel is a slow trickle at best, and many owners report it doing nothing useful. Charge it from a wall adapter.
No. Owners who test it report a usable figure well below the label, which is typical for this product segment.
Depends on the real capacity of your unit, but plan for meaningfully fewer than the 38,800mAh number implies.
No. This model is wired only, via USB-C and USB-A.
No warranty is stated and there is no meaningful brand support.
Only as a cheap, big, rugged camp battery with a flashlight — not as a solar charger, and not if you need accurate capacity or a warranty.
