Home/Universal/Power Banks/38800mAh Solar Power Bank
Read this as a $17.99 rugged camp battery with a flashlight and a carabiner, not as a solar charger. A working unit gives you plenty of USB power for the money and the shell survives a trip. The solar panel is a trickle, and the 38,800mAh figure isn’t the usable capacity.

One-sentence verdict: Worth it as a large, cheap, rugged USB battery for camping or an emergency kit if you treat the solar panel as decoration — skip it if you expect solar recharging or the advertised capacity to be accurate.
A $17.99 rugged battery — the solar panel is for peace of mind, not charging.

A rugged plastic slab with a small solar cell, three USB outputs, a flashlight and a carabiner. It is built for a backpack and takes knocks. The electronics are undocumented, and the capacity claim is inflated like the rest of this segment.
Charge it fully from a wall adapter before a trip — not from the sun. Then plug in your devices.
Usable capacity, charge speed, heat, recharge time and solar input are the measures. Usable capacity is below the label. Charge speed is basic. Solar input is a trickle or nothing, by most owner accounts. Recharging 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, with some units dead on arrival. No warranty, no brand support.
At $17.99 on Amazon (price checked Sep 17, 2026), it is priced as a big cheap battery, and on that basis a working unit is reasonable value.
Judge it as a $17.99 rugged USB battery with a flashlight, not as a 38,800mAh solar charger. If your unit does 20,000–25,000mAh of real capacity, that is still fair for the money. If you get a dead one, there is no recourse. We would call it a fair buy under about $15, expectations low.

If you want capacity you can trust and a warranty, buy an Anker or UGREEN bank. This one is only 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.
This 38800mAh solar power bank is a $17.99 rugged camp battery with a flashlight and a carabiner. On that basis, a working unit gives you plenty of USB power for the money and the shell survives a trip.
The name oversells it. The 38,800mAh is inflated — owner testing lands well below — and the solar panel is a token trickle that many owners say does nothing. Quality is inconsistent, with dead units and no warranty. Its 2.9 score reflects a fine cheap battery and a misleading solar charger. Set expectations to ‘big cheap battery’ and it can be worth it.

This is an unbranded, 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. Use a wall adapter.
No. Owners who test it report a usable figure well below the label, which is typical for this segment.
No. This model is wired only, via USB-C and two USB-A ports.
Depends on your unit’s real capacity, but plan for meaningfully fewer than the 38,800mAh number implies.
No warranty is stated and there is no brand behind the listing.
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.
