Baseus Magnetic Portable Charger 20W 10000mAh: problems, parts and running costs

Checked: 2026-10-16

Summary

Owners most often report that MagSafe wireless charging stops or will not start, usually with a thick case or heat involved, and the pack has no cable in the box. There are no replaceable parts; the only added cost is a USB-C cable. At Baseus’s $22.99 direct sale price it is a fair buy for capacity, but near its $45.99 regular price it is weak.

Common problems and fixes

Wireless charging stops while wired output still works — a r/MagSafe owner reports the pack suddenly stopped charging via MagSafe while still powering devices over cable. Fix: remove the case or use a magnetic case, and let the pack cool. [4]
Charging starts then stops — Baseus’s own support material describes charging that starts for a second then stops, fails with thick cases or wallet cards, and pauses when devices get warm. Fix: remove the case, clear the back and charge out of hot environments. [5]
Heat dissipation and unstable delivery — Baseus’s blog says older 7.5W models often struggle with heat dissipation and stable delivery, which applies to this pack’s wireless class. Fix: charge in a cool spot and expect pauses. [6]
No cable is included — wired charging and self-recharging both need the user’s own USB-C cable; the 30W built-in-cable sibling is a different model. Fix: budget a USB-C cable. [1][2]
Slow self-recharge — ChargerLAB measured about 2h50m at 18W input, not the 1.3 h currently claimed on Baseus’s page. Fix: plan for roughly three hours, or use a stronger charger. [2][1]
A reported overnight failure — a r/batteries post describes a Baseus 10,000mAh pack that blew up in the middle of the night while charging, though the exact model is unconfirmed. Fix: do not leave it charging unattended overnight. [7]

Parts and consumables

No replaceable parts or consumables reported.

Yearly running cost

Not enough data for a per-year figure. There are no consumables or subscriptions; the only added cost is a USB-C cable if none is bundled, and a full 37Wh recharge uses a small amount of electricity.

When it is a good buy

At or below $25: strong value for a MagSafe iPhone owner who wants roughly 1.8 charges in a 204g puck and accepts 7.5W wireless. Baseus’s US store listed $22.99 in October 2026. [1][2]
$26–$40: fair; compare newer 15W Qi2 packs before paying over about $30 for 7.5W wireless. [1][2]
Above $40 ($45.99 regular): weak; certified 15W Qi2 magnetic packs are the same money with roughly double the wireless speed. [1]
Alternatives: the newer Baseus Qi2 22.5W 10000mAh model if 15W wireless matters, and the PicoGo AM61 25W Qi2 if you want a newer budget magnetic pack. [2][8]
