What Unit Pricing Reveals About LEGO Botanicals, Anker’s Power Bank and Hydro Flask

Cents per piece, watt-hours actually delivered, ounces of insulated capacity per dollar -- unit pricing is a blunt tool, but it catches value gaps a sticker price hides.

A LEGO flower set, a power bank and a water bottle don’t belong in the same shopping cart, and this isn’t an attempt to put them there. What they share is a shopping tactic worth applying to all three: breaking a price down into what you actually get per unit — per piece, per watt-hour, per ounce of capacity — rather than trusting the number on the box. Doing that exposes some genuinely bad value, and it isn’t distributed evenly across the LEGO Botanical Collection, the Anker 737 and the Hydro Flask Wide Mouth.

Key facts

• LEGO Hanging Golden Pothos (11512): 372 pieces for $59.99, about 16.1 cents per piece per Brickset
• Anker 737: rated at 86.4 Wh; TechRadar measured 73.1 Wh actually delivered at 140 W, about 85% efficiency
• Hydro Flask Wide Mouth (32 oz): $44.95, 16.8 oz empty per CleverHiker
• LEGO Botanicals range: $14.99 to $109.99 across the current line

Sixteen cents a piece, and Brickset calls it the worst ratio in the line

Brickset’s review of the Hanging Golden Pothos (11512) does the arithmetic plainly: 372 pieces for $59.99 works out to roughly 16.1 cents per piece, which the reviewer called ‘frankly, bewildering’ and the worst per-piece ratio in the Botanicals line. Piece count isn’t the only measure of a LEGO set’s worth, but it’s a useful check against sets that look similarly priced and turn out to deliver very different amounts of actual model.

The same review flagged a design shortcut behind that price: only 12 of the set’s 48 leaves are dual-molded, even though real pothos leaves are all variegated. A piece count alone wouldn’t catch that detail — the set isn’t just expensive per piece, it’s also cutting a corner on the specific botanical detail the collection is meant to be about.

That combination is the real argument for checking unit price at all: a high cents-per-piece figure on its own could simply mean smaller, more detailed pieces, which would be a reasonable tradeoff. Brickset’s review makes clear that isn’t what’s happening here — the price is high and a chunk of the piece count went toward a simplification of exactly the feature that would have justified it.

The rest of the Botanicals range doesn’t share that problem evenly

The Botanical Collection spans $14.99 (Cosmos Flowers, 11514) to $109.99 (Flower Arrangement, 10345), with the Bouquet of Roses (10328) at $59.99 for 822 pieces — about 7.3 cents per piece, less than half the Golden Pothos’s rate at the identical price point. Three sets have already been retired from the line: the Flower Bouquet (10280), Bird of Paradise (10289) and Dried Flower Centerpiece (10314). Retirement tends to push secondhand prices up, which means the per-piece math on those three, bought used today, would look worse than it did when they were new — a cost the sticker price on a current set doesn’t carry.

• Cosmos Flowers (11514): $14.99
• Bouquet of Roses (10328): $59.99 for 822 pieces, about 7.3 cents/piece
• Hanging Golden Pothos (11512): $59.99 for 372 pieces, about 16.1 cents/piece
• Flower Arrangement (10345): $109.99, the most expensive set in the line

A rated 86.4 watt-hours, a delivered 73 to 77

Anker rates the 737 (PowerCore 24K) at 24,000 mAh, or 86.4 Wh, with a $109.99 list price. TechRadar’s own measurement of usable output came in lower across the board: 73.1 Wh delivered at the bank’s maximum 140 W output (about 85% efficiency), 77.1 Wh at 100 W, and 70.5 Wh over a USB-A port. None of that is a defect — some energy loss in conversion is normal for any power bank — but it means the effective price per watt-hour a buyer actually gets is higher than the rated capacity suggests, and it shifts depending on which port and wattage they use.

Run the arithmetic and the gap is real money in relative terms: $109.99 divided by the rated 86.4 Wh is about $1.27 per watt-hour; divided by the 73.1 Wh TechRadar actually measured at full 140 W output, it’s closer to $1.50. Neither figure is what’s printed anywhere on the box, which only advertises the rated capacity — the number a buyer would need to do this math themselves comes from an independent outlet, not from Anker.

On the other side of the ledger, TechRadar also measured a full recharge of the 737 itself in under an hour at 140 W, fast enough that the gap between rated and delivered capacity matters less in daily use than the raw numbers alone imply.

What $44.95 buys in the Hydro Flask Wide Mouth

The 32-ounce Hydro Flask Wide Mouth starts at $44.95, or roughly $1.40 per ounce of stated capacity. Unlike the LEGO and Anker examples, there’s no independent measurement here suggesting the bottle delivers less capacity than advertised — CleverHiker’s main finding was about weight, not volume: 16.8 ounces empty, among the heaviest bottles the outlet tested. That’s a real cost, just not one that unit pricing on capacity alone would catch; a buyer paying per ounce of insulated capacity is also carrying almost a full pound of empty steel before they’ve poured anything in.

OutdoorGearLab’s score of 84 out of 100 suggests testers judged the tradeoff worthwhile overall, which is a useful check on the unit-price math: a bottle can be expensive per ounce and still be rated highly, if what the extra ounces buy — in this case, the insulation behind the 24-hour cold and 12-hour hot claims — is what the buyer actually wanted.

Where the per-unit math stops being useful

Unit pricing is a genuinely useful check against a sticker price, but it has limits. It can’t weigh in on the Anker 737’s fast recharge time, or on whether a LEGO set’s missing dual-molded leaves matter to the person building it, or on the extra weight a Hydro Flask owner carries for insulation a cheaper, thinner bottle wouldn’t provide. Applied narrowly — cents per piece, dollars per watt-hour, dollars per ounce — it mainly does one job well: it tells you when a price and a quantity have drifted apart, which is exactly what happened with the Golden Pothos and, in a smaller way, with the Anker 737’s rated-versus-delivered gap.
