The highest-rated option. Jackery 300's Vision HD Solar & USB delivers 260 lumens with an 80-meter beam and 10%-100% dimming control -- and scores 4.6 stars, the best of the three.

Common misconceptions
What is the real cost?
Per-year cost comparison
BLAVOR 10K ($23.99) vs Jackery 300 ($239.00) vs BLAVOR 20K ($37.59) -- the gap compounds over years. Drag the slider to match your real usage.
At 3 years: BLAVOR 20K costs $2.00/year less than BLAVOR 10K -- about half a cent per day for a brighter beam and a 30-hour runtime.
When to act
Use BLAVOR 10K for 3 real night outings first
If it already solves your problem, keep it. The $1.00-$6.00 switching delta is rarely worth it for hypothetical use cases.
Identify the actual pain point
Is it rating, price, runtime, or charging? If rating: Jackery 300 wins. If price or runtime: BLAVOR 20K wins. Otherwise keep BLAVOR 10K.
Move only if the pain point is documented
Read 10 negative reviews of your target switch. If your pain point appears in 3+ reviews, the switch is justified.
Keep BLAVOR 10K as backup until the new solar charger is proven
Do not sell BLAVOR 10K until Jackery 300 or BLAVOR 20K has been your primary solar charger for 30 days.
Questions the data can and cannot answer
Why would I move from BLAVOR 10K solar charger?
The three real reasons are: (1) you want the highest 4.6-star rating with a trusted brand (Jackery 300), (2) you want the lowest price at $37.59 with 30-hour runtime (BLAVOR 20K), or (3) you want replaceable AAA batteries with no charging wait (Jackery 300). Only switch if at least one is a true pain point.
Is the Jackery 300 really better rated than BLAVOR 10K?
Yes -- 4.6 stars vs 4.2. But note the sample sizes: Jackery 300 has only 11,299 reviews versus BLAVOR 10K's 47,677. Jackery 300's higher rating sits on a statistically thinner base, while BLAVOR 10K is the proven #1 bestseller. Rating is not the whole story.
How much do I save switching to BLAVOR 20K?
Exactly $6.00 -- BLAVOR 20K is $37.59 versus BLAVOR 10K's $23.99. You also gain a longer 30-hour runtime and USB-C charging, but lose the motion sensor and the 2-pack (BLAVOR 20K ships as a single solar charger).
What do I lose switching to Jackery 300 (AAA batteries)?
Jackery 300 uses replaceable AAA batteries instead of USB rechargeable. You lose the motion sensor, the 8-mode flexibility, and USB charging while in use. You gain the 4.6 rating, the Jackery 300 brand, and a 2-pack. It is a feature trade, not a strict upgrade.
What is the difference between a solar charger and a power bank?
For most hands-full users, yes. The wave on/off motion sensor plus long-press off are unique in this set -- no other option lets you toggle the light without touching the lamp. If you hike, camp, or work with dirty or occupied hands, that feature alone justifies keeping BLAVOR 10K.
