Anker Prime Charging Station 250W 6-Port GaN USB C Charger: problems, parts and running costs

Checked: 2026-10-20

Summary

The Anker 250W six-port desktop charger (model A2345) is a desk unit whose main headache is that 250W is one shared budget rather than per-port output: with all six ports busy USB-C1 falls from 140W to 100W and the rest to 45W and 15W, and only the first USB-C port ever reaches 140W. Owners also report a port that will not hold full voltage, a charger that runs warm under load, and a clock display that only works on a 2.4 GHz network. Nothing in it wears out and there are no serviceable parts, so the running cost is effectively zero, and it is worth buying in the $95-$100 band for a desk that charges three or more devices.

Common problems and fixes

“250W” is a shared ceiling, not per-port output — the most common complaint, and a design limit rather than a fault. With all six ports in use USB-C1 drops from 140W to 100W, the other three USB-C ports to 45W and the two USB-A ports to 15W; in Port Priority mode with USB-C1 as the priority port the split is 100W / 45W / 45W / 45W / 15W, and other documented splits include 70 / 70 / 45 / 30 / 15W and 65 / 20 / 20 / 20 / 15W. Warranty does not apply because nothing is broken: the fix is to plan the desk around the shared budget, use the side dial to prioritise one or two ports, or step up to a higher-output charger if you need 300W from two devices. [4][5][7]
Only the first USB-C port reaches 140W — the other three stop at 100W and the two USB-A ports at 22.5W, so a USB-C-only household gets four high-power ports rather than six; hitting 140W also needs a PD 3.1 device and a cable rated for it, and a laptop charging below 140W is not a defect. This is the published specification, so warranty does not cover it: put the laptop on USB-C1 and peripherals on the remaining ports. [7][4][2]
A port that will not deliver full voltage — one owner on r/UsbCHardware reports a port rated for 100W refusing to supply 20V 3A and topping out at 19.6V 2.6A. It is a single report rather than a failure rate, and the cause is unknown: cable, device negotiation, firmware or the unit. Anker’s documented steps are to power-cycle for 5 minutes, reseat the cord, try another cable and another device, then factory-reset through the dial; a genuine fault is covered for 24 months. [10][3][2]
Gets warm under load — Anker’s support page states that it is normal for the charger to get a little warm, and the unit carries over-temperature protection. No independent thermal, efficiency or noise measurement exists for this model, and the ActiveShield 3.0 claim of 6,000,000 temperature checks a day (80 a second) is a manufacturer statement rather than a test result. No fix is needed for normal warmth; repeated shutdowns from overheating are a fault and fall under the 24-month warranty. [3][2][7]
Charging stops or goes intermittent — the support topic Anker addresses for this product: units that stop working, overheat or charge intermittently. The published fix is to power-cycle for 5 minutes, reconnect the cord, try other cables and devices, and factory-reset through the dial. If it still misbehaves the unit is faulty, and warranty covers that for 24 months. [3][2]
Clock mode needs 2.4 GHz Wi-Fi and has no alarm — the screensaver clock only appears when the station is on a 2.4 GHz network, and the display cannot wake you. Workaround: keep the station on a 2.4 GHz network and the alarm on a phone. Both are documented behaviour, so warranty does not apply. [4][7][2]
Cable clutter from the front-mounted ports — How-To Geek lists the messy front port layout among the cons of the desk unit, and at 640 g (about 1.41 lb) with the AC socket underneath it is not a unit you move around. Workaround: short right-angle cables routed along the back edge of the desk. Not a warranty matter. [8][4]

Parts and consumables

No replaceable parts or consumables reported. Nothing in the unit wears out on a schedule, it has no user-serviceable internals, and Anker documents no spare-parts programme and no repair channel for this model. The only things an owner ever buys are cables.

240W USB-C cable — no part number; a cable rated for the full 140W is needed to pull maximum output from USB-C1. Anker sells the charger bundled with a 240W USB-C cable for $184.99 (Anker US, October 2026). [1][2]

Yearly running cost

Effectively zero on the parts side: there are no consumables, no wear parts and no service schedule, the app is optional with no subscription reported, and the 24-month warranty covers defects inside that window. The only recurring outlay is the electricity the station draws from the wall, which no source quantifies, so no exact yearly figure is available; computed as parts, consumables and service, the owner spends $0 a year.

When it is a good buy

Price anchors, all from stores other than the main marketplace:

Anker US store: $149.99, compare-at $199.99 (October 2026). [1]
Anker US store, bundle with a 240W USB-C cable: $184.99 (October 2026). [1]
Best Buy: $149.99 (October 2024, per TechRadar’s review). [9]
Anker Canada store: CA$189.99 (October 2026). [13]
Anker EU store: €116.90, also listed at €166.99 (2024). [14]
Anker Nordics store: 2,299 kr (October 2026). [11]

Deal coverage put it at $99.99 (PCWorld, June 2026) and $95 (Macworld, August 2026), so treat the $95-$100 band as the point where the 2.26-inch display and the dial earn their place. Around $110-$130 it is a good buy if the desk charges three or more devices; $140-$150 is fair; above $170 the premium over plainer high-output chargers is hard to justify unless per-port control is essential. For what it is, the reviews are solid: Macworld named it an Editors’ Choice and How-To Geek scored it 8/10. [4][6][5][8]

Alternatives: Anker’s own 200W six-port GaN charger, about $85 (Anker US store, October 2026), covers the same port count with less power and no screen, and is the better choice when you do not need per-port control. The UGREEN Nexode 300W, with four USB-C ports, one USB-A port and 300W of total output, is the better choice when raw output matters more than the display. The Satechi 200W six-port USB-C charger, six USB-C ports and no USB-A, is the better choice when everything you own is USB-C. [1][5][8]
