Baseus 30W Dual-Port Super Si Wall Charger: problems, parts and running costs
Checked: 2026-10-20
Summary
The charger itself is electrically solid — measured efficiency of roughly 84–90%, stable 30 W output and the full protocol set on the USB-C port — but the listing it comes from calls it a “wireless portable charger” when it is a corded wall plug with no battery and no wireless coil, so the most common problem is buying the wrong thing. What owners actually complain about is durability: Baseus charger discussions mix years of trouble-free use with units that start dropping connections or fail within months, and no exact-model failure rate exists. Running cost per year is effectively zero because there is nothing to replace, and it is a good buy at about $19.99 from Baseus direct (October 2026) and only fair above $30.
Common problems and fixes
- It is not a power bank or a wireless charger — the listing title says “Wireless Portable Charger”, but the unit has AC 100–240 V input with foldable US prongs and measures about 48.35 × 35.30 × 30.11 mm at 64.2 g, which is the plug-in adapter, not a battery pack. There is no battery and no wireless coil, so a phone on this charger always needs a cable. Fix: if you wanted a power bank, buy a power bank; if you wanted a plug-in charger, this is the right shape. [1][2]
- Two devices at once get less than the 30 W headline — Baseus rates simultaneous use at 18 W on USB-C and 12 W on USB-A, and ChargerLAB measured 14.22 W and 12.82 W, a 27.04 W total, with a Samsung S20 Ultra and a Redmi K50 attached. The full 30 W is a single-port USB-C figure. The USB-A port also has no PD and no PPS, only Apple 2.4A, QC2.0/3.0, AFC, FCP, SCP and PE. Fix: charge one phone on USB-C when you want fast charging, and put slower accessories on USB-A. [1][2]
- It will not charge a laptop — Baseus marks the model “Macbook Compatible: ✘” and states that dual-port power is not enough to charge a computer; ChargerLAB still drew about 28.62 W from a MacBook Pro 16" and an iPad Pro, and about 25.69 W from a Mi 11. Fix: for anything bigger than a phone or small tablet, buy a higher-wattage charger. [1][2]
- It runs hot under load — a one-hour full load in a 25 °C chamber reached 66.9–67.7 °C on one side and 61.8–63.3 °C on the other. The “up to 10% less heat” Super Si claim was never tested against a control unit, so treat that claim as unverified. Fix: keep it out of a pocket, sleeve or soft surface while charging and give it ventilation. [1]
- Early failures and dropped connections — Baseus charger discussions mix owners with years of trouble-free use against owners whose units failed within months or dropped the connection intermittently, including one owner who hit the same problem across three separate units. There is no teardown or exact-model failure rate for this SKU, so treat this as a caution about the brand rather than a confirmed defect list. The warranty does not help much here: Baseus advertises a “Hassle-Free Warranty” but the term was not confirmed from a primary source, while the stated policy is a 7-day no-reason return and a 30-day after-sales guarantee for a manufacturing defect with free return, exchange or repair inside that window. Fix: test the unit thoroughly inside that first month. [2][4][8]
- The 2025 recall does not cover this charger — the CPSC recall of Baseus battery power banks (65 W, 30000 mAh, model BS-30KP365) is for units with cells that can overheat; this charger is a mains adapter with no battery and is not part of it. Fix: do not rule the charger out because you read about the power bank recall. [6]
Parts and consumables
No replaceable parts or consumables reported. The unit has no user-serviceable parts, ships with a manual and a sticker and no cable, and there is nothing to replace on a schedule. [1][2]
Yearly running cost
Nothing recurring. There are no consumables, no replacement parts, no accessories to swap and no subscription; the only running cost is grid electricity for whatever you charge, and the sources publish no electricity rate and no charging-session power figure, so no dollar total can be computed from them. The one figure that can be scaled is standby draw, 0.161 W at 110 V 60 Hz and 0.163 W at 220 V 50 Hz with nothing connected, which is the charger’s own overhead whether or not you use it. [1]
When it is a good buy
- $19.99 or below (Baseus direct, black US version, October 2026): good value for a compact dual-port 30 W charger with strong measured electrical performance.
- $21.99 (Baseus direct, white US version, October 2026): acceptable; competing 30 W dual-port chargers, including GaN models, become relevant, and the silicon design plus the durability caution cut into the edge.
- $31 to $40: weak for this particular charger; the premium buys neither GaN, nor more wattage, nor any documented long-term reliability.
- Above $40: poor value; at that price buy a charger with a stronger independent test record.
Baseus sells this line direct at $19.99 for the black US version and $21.99 for white, with the Super Si collection page listing the line from $19.99 (October 2026). [2][3] A third-party Newegg listing for the same 30 W dual-port USB-C charger exists, but no price was confirmed for it. [7] Three alternatives suit other needs: the Baseus Compact 3 Ports Fast Charger 30W is the better choice when you regularly charge three devices at once; a GaN dual-port charger is the better choice when size or heat matters, because this unit uses a silicon Super Si chip rather than GaN, and competing 30 W dual-port chargers including GaN units start to matter once the price moves up; and a charger rated for laptops is the better choice when a computer is in the loop, since this one is marked “Macbook Compatible: ✘” and its dual-port output will not charge a computer.
