Solar vs alternator charging comes down to a campsite at dusk with a dead phone: the sun is gone, the engine is off, and the only power left is what was banked during the day. The short answer: choose the alternator charger when the engine runs daily and the power station needs a fast refill, and choose the solar bank when the loads are phones and small devices away from the vehicle. The two listings below make the trade concrete.

Charge rate and what gets charged
On raw charge rate the figures are 800W against 20W, but they describe different jobs. The Anker is an 800W alternator charger that the listing says fills a 2kWh Anker SOLIX power station in 3 hours, up to 8 times faster than a car auxiliary port. The BLAVOR is a 10,000mAh bank with 20W USB-C that the listing says takes an iPhone 15 to 65% in 30 minutes, charging 3 devices at once with Qi wireless. Compare them as methods, not as rivals: one refills a power station, the other tops up phones.
Where each method works
The Anker only charges while the vehicle runs. It mounts with a battery connection cable and a 100A fuse wire, and the listing claims compatibility with 99% of RVs and gas vehicles. The BLAVOR works anywhere: pocket-size at 9.3 ounces with an IPX5 rating, a solar panel for trickle top-ups, and dual flashlights. The listing does not state the solar panel wattage, so treat the solar input as a slow top-up, not a primary charge source.
Certifications and warranty
The Anker spec table lists UL, CE, FCC and IEC, but states no warranty term. The BLAVOR lists an IPX5 rating and a flame-retardant ABS and PC housing, with a 3-year warranty in the spec table. Note the BLAVOR spec table also says Warranty Description: no, which contradicts the 3-year entry; the longer, specific entry is the one to go by, and the contradiction is worth knowing before purchase.
What the listings leave unclear
The BLAVOR listing has the most internal friction: lithium-cobalt in the bullets against Lithium Polymer in the spec table, and dimensions as both 5.91 x 3.07 x 0.87 and 5.9 x 3.1 x 0.8 inches. The Anker listing is cleaner but leaves the warranty unstated and ties the charger to Anker SOLIX power stations. Neither listing states what the other side would need to be judged against it, so the honest read is two separate tools, not two versions of one tool.

How the picks are scored
The Solar Score weighs performance, build, value, safety and warranty. For charging gear, safety means stated certifications, ratings or protections; the Anker lists UL, CE, FCC and IEC, and the BLAVOR lists an IPX5 rating and flame-retardant housing. Only the BLAVOR states a warranty term, 3 years. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Anker SOLIX 800W Charger | 9.6 | 33 | 21 | 20 | 7 | 0 |
| BLAVOR PN-W05 Solar Bank | 9.5 | 27 | 19 | 20 | 5 | 2 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Solar vs alternator charging: which should you choose?
Choose the alternator charger if the engine runs every day and the goal is refilling a power station fast: 800W with app control, at the cost of installation and a running engine. Choose the solar bank if the loads are phones, earbuds and small USB devices and the priority is pocket-size portability with a trickle of solar. For a mixed setup, the two methods complement each other: alternator for the big refill on driving days, solar bank for the small devices at camp. See how charging methods compare in the DC to DC charger vs MPPT charge controller guide.

Sizing Notes
- Match the charger’s stated output to the power station it feeds: the Anker is built for Anker SOLIX stations.
- Size the bank to the loads: the BLAVOR is a 10,000mAh phone-scale bank, not a power station charger.
- Fuse the alternator charger’s positive lead as the manual directs; the box includes a 100A fuse wire.
- Check the 99% compatibility claim against your own RV or vehicle before buying.
