Anker 737 Power Bank (PowerCore 24K) (A1289 / A1289011)
Published · Researched 2026-09-21
2026 lineup note: The Anker 737 (PowerCore 24K) is still a current, widely sold model in the US in 2026 — Anker has NOT renamed or replaced it. The newer Anker Prime line (e.g. Prime 26K/27,650 mAh, 250–300 W, app control) is the upgrade path above it, not a replacement. One EU retailer (Alza, Czechia) lists the 737 as discontinued in its catalog — flagging regional availability variance; it remains in stock at Anker US and Amazon US. Exact 2026 model name: Anker 737 Power Bank (PowerCore 24K), model A1289; US variant SKU A1289011 (black).
Version lineage (2023–2026)
- July 2022: Anker 737 Power Bank (PowerCore 24K) launched at $149.99 — 24,000 mAh, 140 W PD 3.1 two-way charging, smart digital display, GaNPrime platform. Model number A1289.
- 2023: Anker launched the Prime sub-brand (Prime 250 W 27,650 mAh, Prime 130 W, Prime 200 W) — higher output, app/Bluetooth, TFT display. The 737 remained the value flagship.
- 2024–2025: No hardware revision of the 737. Anker's naming shifted toward "Anker Prime" for new products, but the 737 name persisted on the same A1289 hardware.
- 2026: Still current in the US; frequently discounted to $50–110. The Medium tech-comparison piece "Anker 737 vs Anker Prime" (Feb 2026) calls the 737 "still the GOAT" — preferred by some users for 5A PPS support (fastest Samsung charging) and a more durable, less scratch-prone display than the Prime.
- Smart-buy advice: Buy on sale — it routinely drops 40–60% off MSRP. If you need 200 W+ or app control, look at the Prime line; for 140 W laptop charging at the lowest Anker price, the 737 is the one.
Overview
The 737 is Anker's high-wattage travel power bank: 24,000 mAh with 140 W USB-C PD 3.1 output — enough to charge a 16" MacBook Pro at full speed — plus a smart digital display showing per-port wattage and time-to-full/empty. Two USB-C + one USB-A port. Bi-directional charging refills the bank itself at up to 140 W (0–100% in roughly an hour). Made by Anker Innovations. In 2026 it remains the reference "big" power bank for laptop travelers, campers, and Steam Deck / handheld-console users.

Support & Parts
Anker support is generally well regarded (responsive, warranty honored), with global coverage. Known issues: the 737 is heavy (630 g) for a "power bank" — it's a brick; some users report the USB-A port's 18 W ceiling is stingy; early units had display firmware quirks (resolved). No widespread failure reports in 2024–2026; the unit has a reputation for surviving drops (Medium/Reddit anecdotes).
Community Verdict
The 737 remains a community favorite in 2026 — the Medium "737 vs Prime" comparison calls it "still the GOAT," citing its tank-like build, the genuinely useful smart display, and 5A PPS support that some newer Prime models lack (faster Samsung phone charging). Owners on deal forums (OzBargain, SlickDeals-adjacent) treat sub-$80 pricing as an instant buy. The honest debate: 737 vs Anker Prime — Prime wins on total output (250–300 W), recharge speed, and app control; 737 wins on price, durability, and simplicity. For camping, it's the "laptop charger in your pocket" that bridges phone banks and full power stations.

Key Specs — gap-fill additions
- Weight: 630 g (1.39 lb) — heavy for a "power bank," light for a laptop charger.
- Energy: 24,000 mAh; sources cite 86.4 Wh and 87.36 Wh — conflict unresolved as of 2026-09-20, carried as UNVERIFIED. Either way, safely under the 100 Wh airline carry-on limit.
- I/O: 140 W PD 3.1 in and out via USB-C1 (0–100% in ~52–60 min with a 100 W+ brick); 2× USB-C + 1× USB-A (18 W).
- Warranty: 24 months (per batteryskills.com's spec summary) — better than the 12–18-month norm for power banks.
- In the box: short 140 W USB-C cable included; no wall brick — you supply the 100 W+ charger for fast refills.
Long-term durability & warranty-claim reality
- The display is the fragile bit. A July 2026 shopabunda/Amazon reviewer: "the plastic in front of the screen is very vulnerable to knocks and drops, and mine has gotten a crack in that plastic, which makes the display hard to read from some angles." The glossy front panel also scratches easily (worldtimesnow.com). The unit keeps working — you just lose the readout that justifies the premium. A soft pouch is cheap insurance.
- Parasitic drain is a settings issue, not a defect. Anker's own support article: with "Auto Screen Off" disabled, the screen + MCU draw ~15% per day; a USB-C-to-Lightning cable left plugged in drains it even with no phone attached. Enable auto-screen-off, unplug cables, and standby loss becomes a non-issue.
- Pass-through quirk: the bank prioritizes the connected device and only charges itself after the device stops drawing (shopabunda reviewer; desertcart reviewer calls it "poorly-implemented"). Don't plan overnight pass-through as a charging strategy.
- Negotiation hiccups: isolated reports of PD negotiation issues with Dell Precision laptops when hot-plugged (desertcart review) — test your specific laptop before a trip.
- Cell aging: worldtimesnow (2026 review) cites users reporting "minimal degradation" after 6 months of heavy use; Reddit themes (via pctechbits) put real-world delivered capacity at 80–85% of theoretical — standard for the category — with durability generally praised over months of regular use.
- Warranty-claim reality: 24-month Anker warranty; Anker's support is widely regarded as responsive (advance-replacement culture). The display window is the claim most likely to be contested as "physical damage" — hence the pouch advice.
Version history — year by year
- 2022: launch at $149.99 — 140 W PD 3.1, smart display, GaNPrime (A1289).
- 2023–2025: no hardware revision. Street price collapses through deal cycles ($49.99–109.99 by 2026) while MSRP stays $149.99.
- 2026: still current as of 2026-09-20. The Anker Prime 26K/27,650 mAh banks are a separate premium line (glossier TFT display, "Prime" branding) — not 737 replacements.
Head-to-head vs closest rivals
- vs Nitecore NB10000 Gen 3: the 737 is the laptop bank (140 W, 630 g); the NB10000 is the backpacking bank (22.5 W, 150 g). If your trip includes a USB-C laptop, the 737; if it's phones and headlamps, the NB10000 at less than 1/4 the weight. They don't compete — they cover different trips.
- Street-price note: the 737's deal pricing ($49.99–109.99) has made it the value flagship despite the $149.99 MSRP — never pay list.
Care & maintenance
- Store at ~50% charge in a cool, dry place; top up every 3 months if unused (batteryskills/Anker guidance).
- Turn ON "Auto Screen Off"; never store with cables plugged in.
- Use a 100 W+ USB-C brick for refills (52–60 min); a phone brick works but takes hours.
- Pouch it — the display window is the durability weak point.
Buying traps
- Never pay $149.99. Street runs $49.99–109.99 on deal cycles (2026) — the MSRP is an anchor.
- 737 vs Prime: the Prime 26K/27.6K banks look similar but are a different, pricier line — buy by model number A1289 if you want the 737.
- No wall brick in the box — budget a 100 W+ GaN charger or your refills will be slow.
- Pass-through isn't real pass-through — it won't charge itself while feeding a device in most cases.
Community Verdict — additional voices (Sept 2026)
- pctechbits.com (summarizing Reddit): consistent themes — "durability: many users report the power bank holding up well after months of regular use"; "value proposition: while acknowledging the premium price, most users feel the performance justifies the cost"; real-world capacity ~80–85%. "Tech-savvy users particularly value the detailed power delivery information shown on the display."
- shopabunda/Amazon (Alexander, July 2026): "the plastic in front of the screen is very vulnerable to knocks and drops... Despite these flaws, the pack does handle high speed charge/discharging very well, staying surprisingly cool. Would buy again."
- worldtimesnow.com (2026 review): "For most users, the 737 (PowerCore 24K) remains the better buy because the price has dropped significantly in 2026" vs the Prime line.
- Anker support (official): on fast drain — enable Auto Screen Off, unplug cables in storage; ~40% of rated capacity is lost to conversion heat, so 24,000 mAh delivers ~13,000–14,000 mAh to devices. Set expectations accordingly.
