# Trek4Tech engineering reference

> Specifications, editorial ratings, dated research and calculated scenarios for portable power. [Source index](https://www.trek4tech.com/llms.txt). Generated 2026-11-10 UTC.

The [Trek4Tech Research Team](https://www.trek4tech.com/about#editorial-team) writes the reviews. [Robert](https://www.trek4tech.com/about#robert) is a member. Runtime tables are estimates from rated capacity and assumed load.

## Planning methods

- **Trek4Tech AC Runtime Estimate**: usable Wh = rated Wh × 0.85. Divide by average device watts for hours. Divide hours by sleep hours per night and round down to the nearest half-night.
- **Trek4Tech Solar Planning Estimate**: effective field W = min(rated panel W × 0.65, maximum station solar input W). Peak-sun hours to refill = rated Wh ÷ effective field W.
- **Trek4Tech Compressor Surge Estimate**: startup apparent power in VA = nameplate locked rotor amps × 120 V. Compare the running load, outlet limit, startup capability and duration. Exclude resistive lifting modes from the motor-start screen.
- **Trek4Tech Lifetime Energy-per-Dollar Index**: rated Wh × rated cycles to 80% ÷ 1,000 ÷ dated street price, in kWh per dollar. The ratings worksheet identifies the price check used for each score.

[Research method](https://www.trek4tech.com/how-we-research) and [dated ratings worksheet](https://www.trek4tech.com/ratings). Each worksheet value uses the price on its stated check date. Confirm current price and availability with the retailer.

## How we score

We score each factor from 1 to 5 within its product class. Power stations and solar bundles use five weighted factors. Solar panels use four.

### Power stations and solar bundles

| Factor | Weight | What we look at |
| --- | --- | --- |
| Longevity | 25% | Battery chemistry and rated cycle life — the spec that decides whether a station lasts three years or twelve |
| Output headroom | 20% | Continuous and surge output relative to capacity class, and whether it starts real compressor loads |
| Solar intake | 15% | Maximum solar input relative to capacity — how fast you can refill it off-grid |
| Recharge speed | 15% | Time to a full charge from a wall outlet **using the power supply included in the box**. Where a manufacturer sells a faster supply separately, we score what you get by default and note the upgrade in the review. |
| Value | 25% | Capability per dollar at typical street price, not list price |

Solar panels are scored on four factors instead of five — a panel has no battery to recharge.

### Solar panels

| Factor | Weight | What we look at |
| --- | --- | --- |
| Real-world yield | 35% | Cell efficiency, bifacial gain, and the wattage we'd expect in the field rather than at STC |
| Build and weather resistance | 25% | IP rating, hinge and stand durability, deployment format |
| Compatibility | 15% | Connector standards and how well it works outside its own brand |
| Value | 25% | Watts per dollar at typical street price |

### What the bands mean

- **4.5–5.0** — Class-leading. Hard to beat for its intended buyer.
- **4.0–4.4** — Strong. A clear recommendation with a known tradeoff.
- **3.5–3.9** — Competent but compromised. Buy it for one specific reason.
- **3.0–3.4** — Specialist or outclassed. Buy it for the one thing it does that bigger options don't, or on price.
- **Below 3.0** — Dated. We still list it only where it leads on a single genuine strength, and we say what that is.

### Factor anchors

Weights tell you how much each factor counts; anchors tell you what a 3 or a 4 means on that factor. Each factor is scored 1–5 against the tables below, and the weighted sum is the published rating — so you can rebuild any of our scores from the specs in the review.

#### Longevity — rated cycle life to 80% capacity

| Score | Anchor |
| --- | --- |
| 5 | 5,000+ cycles |
| 4.5 | 3,500–4,999 cycles |
| 4 | 3,000–3,499 cycles |
| 3 | 2,000–2,999 cycles |
| 2 | 1,000–1,999 cycles |
| 1 | Under 1,000 cycles |

We use the manufacturer's published cycle rating. Chemistry isn't scored separately — it's already expressed in the cycle count.

#### Output headroom — continuous and surge output relative to capacity class

We score both an absolute-watts table and a proportionate table (continuous watts ÷ rated watt-hours), take the higher of the two, then apply the surge modifier. A station qualifies either by driving large loads outright or by being well-proportioned to its own battery — a small station shouldn't be penalized for being small.

| Score | Absolute output |
| --- | --- |
| 5 | 3,000W+ continuous, or 120/240V dual voltage for hardwired circuits |
| 4 | 1,800–2,999W |
| 3 | 1,200–1,799W |
| 2 | 600–1,199W |
| 1 | Under 600W |

| Score | Proportionate output (continuous W ÷ rated Wh) |
| --- | --- |
| 5 | 1.80 W/Wh or higher |
| 4 | 1.40–1.79 |
| 3 | 1.00–1.39 |
| 2 | 0.70–0.99 |
| 1 | Under 0.70 |

Surge modifier, applied after taking the higher of the two scores above and capped at 5.0: **+0.3** if surge is 2.0× continuous or better, **−0.3** if surge is under 1.5×.

#### Solar intake — max solar input ÷ rated capacity (W per Wh)

| Score | Anchor |
| --- | --- |
| 5 | 0.80 W/Wh or higher |
| 4 | 0.55–0.79 |
| 3 | 0.40–0.54 |
| 2 | 0.25–0.39 |
| 1 | Under 0.25 |

#### Recharge speed — AC time to full on the in-box power supply

| Score | Anchor |
| --- | --- |
| 5 | Under 60 minutes |
| 4 | 60–90 minutes |
| 3 | 91–150 minutes |
| 2 | 151–300 minutes |
| 1 | Over 300 minutes, or the manufacturer publishes only an accessory-gated figure |

Where an advertised time requires a supply or cable sold separately, we derive the in-box floor (rated Wh ÷ in-box AC input watts), state the arithmetic in the review, and score the floor. We never score the advertised figure.

#### Value — rated lifetime energy per dollar

(capacity Wh × rated cycles) ÷ 1000 ÷ street price, in kWh per dollar. Street price, never list. If a product has no current street price, we use the last price recorded on a dated check and say so. We re-score value at every weekly price check, so a rating can move when the street price does; the [ratings worksheet](https://www.trek4tech.com/ratings) shows the price and check date behind each score.

| Score | Anchor |
| --- | --- |
| 5 | 6.0 kWh per dollar or higher |
| 4 | 4.0–5.9 |
| 3 | 2.5–3.9 |
| 2 | 1.5–2.4 |
| 1 | Under 1.5 |

Adjusted ±0.3 for value that isn't energy: a bundled panel, retail-returns availability, an ecosystem expansion path, a best-in-class app. The review says which adjustment was applied and why.

### Panel factor anchors

#### Real-world yield — cell technology and published efficiency

| Score | Anchor |
| --- | --- |
| 5 | Bifacial and published cell efficiency 23%+ |
| 4 | Bifacial, or single-sided with published efficiency 23%+ |
| 3 | Single-sided with published efficiency 20–22%, or efficiency not published |
| 2 | Single-sided with published efficiency under 20% |
| 1 | Documented underperformance in the manufacturer's own spec or warranty terms |

Rated wattage isn't scored here — a 100W panel isn't a worse panel for being 100W, it's a different category. An absent efficiency figure is an information gap, not evidence of poor performance, and scores a 3. Instead, each review states which station class the panel suits (a 100W panel suits sub-500Wh stations and daytime top-ups; a 400W panel suits 2kWh+ stations).

#### Build and weather resistance — published IP rating and deployment format

| Score | Anchor |
| --- | --- |
| 5 | IP68 |
| 4 | IP67, or IP65 with an integrated adjustable stand |
| 3 | IP65, or no IP rating published with otherwise solid construction |
| 2 | No IP rating and no stand |
| 1 | Known durability complaints in the manufacturer's own warranty terms |

#### Compatibility

| Score | Anchor |
| --- | --- |
| 5 | Standard MC4, works across brands with no adapter |
| 4 | Standard connectors, adapter needed for some brands |
| 3 | Native to one brand, adapter required elsewhere |
| 2 | Proprietary connector, adapter not sold |
| 1 | Locked to a single product |

#### Value — rated watts per dollar at street price

The bands come from the panel catalogue we actually track, not from invented thresholds: 3 sits at the catalogue median, 5 at the best, 1 at the worst, with 4 and 2 spaced evenly between. Across the six panels we list (street prices from dated checks between 2026-06-27 and 2026-07-23), the median is 0.58 W per dollar, the best 0.81, the worst 0.40. That yields:

| Score | Anchor |
| --- | --- |
| 5 | 0.75 W per dollar or higher |
| 4 | 0.64–0.74 |
| 3 | 0.54–0.63 |
| 2 | 0.45–0.53 |
| 1 | Under 0.45 |

These bands are recomputed when the catalogue or its prices change materially, and the thresholds published here are updated with them.

The factor-by-factor derivation of every published rating — each factor score, the spec it came from, and any adjustment applied — is recorded in our [ratings worksheet](https://www.trek4tech.com/ratings), so any score can be checked line by line.

One note on recharge speed, because it is the factor manufacturers most often overstate. Several stations advertise an AC charge time that is only reachable with a power supply or cable sold separately, and in at least two cases the advertised figure is arithmetically impossible on the cable in the box. Where we find that, we score the default configuration, show the arithmetic, and say what the upgrade costs you.

Ratings track product merit, not stock status. A product we rate highly may still be unavailable — where that's true, we say so in the review rather than quietly adjusting the score.

## CPAP model scenarios on a 1,024 Wh station

The wattages are example inputs, not measured overnight draws. AC uses 870.4 Wh. The DC column is an upper bound before station and converter losses. Use the average measured with your own prescribed settings.

## Solar recharge and daily harvest reference

[Solar Recharge Calculator](https://www.trek4tech.com/tools/solar-recharge). Effective input W = min(rated array W × 0.65, station solar-input limit). Refill peak-sun hours = rated capacity Wh ÷ effective input W, from empty with no connected load and before charge taper. Calculations use full precision before display rounding. Check panel voltage, current, connectors and allocation across MPPT inputs.

### Potential daily harvest at 4.5 peak-sun hours

Each array cell shows estimated station-input energy and its AC energy budget after × 0.85. An 800 W array yields 520 W before clipping, so a 500 W input clips while a 600 W input does not.

Example AC consumption: a CPAP averaging 60 W for 8 hours uses 480 Wh; a cycling refrigerator averaging 65 W for 24 hours uses 1,560 Wh. Check motor startup separately. Potential daily harvest requires battery headroom, daytime consumption or extra storage. Overnight AC storage is limited to rated Wh × 0.85. Peak-sun hours vary by location, season, weather, shade and panel angle; use local monthly data from [PVWatts](https://pvwatts.nlr.gov/).

## Manufacturer preview

[Anker SOLIX S5000](https://www.trek4tech.com/products/anker-solix-s5000): 5024 Wh, 4500 W AC, 8000 W claimed peak, 120/240 V. Manufacturer specs checked October 22, 2026; pre-release coverage, no verified retailer offer. The 3000W total requires two suitable arrays: up to 1000W at 11–60V / 17A and 2000W at 16–165V / 17A. This estimate assumes a valid allocation across both inputs; it does not verify panel wiring or compatibility. [Manufacturer](https://www.ankersolix.com/s5000).
