Baseus EnerGeek GP12 145W 20800mAh: problems, parts and running costs

Checked: 2026-10-17

Summary

The GP12’s 145W output is a two-port combined figure — a single USB-C port peaks at 100W — and no independent lab has measured this exact model, so every performance number is a manufacturer claim. Brand-level owner reports include a swollen battery and a unit that stopped holding charge after four months. Running cost is $0 a year with no consumables; it is a good buy on a discount well below its $89.99 list price.

Common problems and fixes

145W is shared across two ports — single-port peak is 100W; the 145W split only happens across the two USB-C ports together and buyer sheets disagree on the secondary-port figures. [1][8]
No independent test — no RTINGS, Wirecutter, Tom’s Guide, CNET or PCMag instrumented test of this exact model exists; ChargerLAB’s teardown is the different 25,000mAh E0028H unit. [7]
Trickle charging above 80% — the bank deliberately slows to trickle charging above 80% as battery protection; not a defect, but it makes the end of a recharge noticeably slower. [1]
Full recharge speed needs a separate charger — the 65W recharge input requires a 65W+ USB-C wall charger that is not included in the box. [1]

Parts and consumables

No replaceable parts or consumables reported. The battery is lithium polymer and the unit is not user-serviceable.

Yearly running cost

$0 per year. There are no consumables, no filters, no subscriptions and nothing to replace; the box includes a 100W USB-C to USB-C cable, so the only thing owners may add over time is a 65W+ USB-C wall charger (not included) to use the full recharge speed.

When it is a good buy

Baseus’s US store lists it at $89.99 (listed “Sold out” at check time, October 2026); launch coverage reported $99.99 (Gizmochina, June 2026). [1][3]
2025 deal coverage tracked it as low as $44.99 (TechEBlog, April 2025; IGN deal post). [5][6]
At or below the official $89.99 it is a competitively spec’d 77Wh laptop power bank; above about $90 with no discount the case weakens — no independent test validates real-world output and brand-level feedback includes battery-durability cautions. [1][7][11]
The strongest purchase trigger is a documented discount. Alternatives: the Baseus EnerGeek GR11 (20,000mAh, 145W, retractable cable) is the better choice when you want a built-in cable; the EnerFill FC41 (25,000mAh, built-in cables) when you want more capacity; the EnerCore CR11 (20,000mAh, 67W) when you do not need 145W output.
