Home/Universal/Power Banks/YELOMIN 59800mAh Solar + Crank Bank
The YELOMIN 59800mAh Solar + Hand-Crank Bank is a well-conceived go-bag object: built-in cables, a wireless pad, a flashlight and a rugged waterproof-rated shell in one unit. The numbers behind the pitch — the 59,800mAh, the crank, the solar panel — are where it falls short.

One-sentence verdict: Worth it as one rugged unit with built-in cables, a wireless pad and a big battery if you treat the crank and solar as emergency-only extras — skip it if you’re judging it by the 59,800mAh figure, the crank or the solar panel as real charging methods.

Built-in cables, a crank, a wireless pad and solar — the crank is a novelty, not a charger.

| Version reviewed | YELOMIN 59800mAh solar + hand-crank power bank · ASIN B0F2FPLLGQ · Amazon US |
A large, rugged, waterproof-rated block with three captive cables, a wireless pad on top, a fold-out solar panel, a hand crank and a flashlight. As an object for a go-bag it is well conceived — everything is attached, nothing to lose. The problem is that three of its headline features (capacity, crank, solar) do not deliver what the listing implies.
Charge it fully from a wall adapter before you need it — that is the only practical way to fill it. Then use the built-in cables or the wireless pad.
For a power bank, performance is usable capacity, charge speed, heat, recharge time and alternative inputs. Usable capacity is well below the label. Wired charging via the built-in cables is basic but works. Wireless is 15W nominal, 7.5W to an iPhone. Solar and crank inputs are emergency-token, not real. Recharging the big battery from a wall adapter takes many hours.
Works with:
Not compatible:
The shell is genuinely rugged and water-resistant. The electronics are unverified and inconsistent unit to unit, with no warranty behind them.
At $49.99 on Amazon (price checked Sep 17, 2026), you are paying a premium over a straightforward big battery for the crank, the wireless pad and the built-in cables.
Judge it as a rugged ~25,000–30,000mAh emergency unit with built-in cables and a wireless pad, and the price is borderline. Judge it by the 59,800mAh, the crank or the solar, and it is poor value. For $49.99 you could buy an honest, verified-capacity 20,000mAh bank with a warranty. We would call it a fair buy under about $32, expectations set low.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| YELOMIN 59800mAh Solar + Crank Bank (this bank) | A rugged all-in-one emergency unit | Built-in cables, wireless pad, flashlight, tough shell | Inflated capacity; token crank and solar; no warranty; $49.99 | $49.99 |
| YELOMIN 38800mAh Solar Power Bank | The same idea for less money | Cheaper; flashlight; carabiner | Same inflated capacity and token solar | $17.99 |
| UGREEN Nexode 20,000mAh 45W | Honest capacity and real speed | Verified 20,000mAh, 45W, display, warranty | No flashlight, crank or solar | $34.98 |
For roughly the same money, the UGREEN Nexode 20K gives you verified capacity, real speed and a warranty. This YELOMIN only makes sense if the built-in cables and the go-bag format specifically appeal and you ignore the crank and solar. Prices are Amazon figures from August 26, 2026.
The YELOMIN 59800mAh Solar + Hand-Crank Bank is a well-conceived go-bag object: built-in cables, a wireless pad, a flashlight and a rugged waterproof-rated shell, all in one unit with nothing to lose.
Three of its selling points do not hold up. The 59,800mAh is inflated, the hand crank produces seconds of talk time for minutes of effort, and the solar panel is a token trickle. At $49.99 you are paying a premium for a feature list whose headlines are soft. As a rugged ~25,000mAh emergency unit with built-in cables it is borderline value; judged by its name, it is poor. Its 2.9 score reflects that gap.

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 59,800mAh.
Not meaningfully. Minutes of hard cranking yields seconds of talk time. It is a genuine last resort, not a charging method.
Not practically. The fold-out panel is a slow trickle, and many owners report it doing nothing useful.
No. Owners who test it report a usable figure well below the label.
Yes, a 15W pad on top — 7.5W to an iPhone.
No warranty is stated and there is no meaningful brand support.
Only if the built-in cables and go-bag format specifically appeal. For verified capacity and a warranty, a UGREEN Nexode 20K ($34.98) is the better buy.
