The Baseus EnerFill FC11 E0031100 is a 20,000 mAh, 45 W power bank, but “Anker 20,000 mAh” describes several different products—not one direct competitor. Compare the FC11 with a specific Anker model, then check charging output, cable and port layout, shared power, and carry weight against the devices you actually use.
Identify the exact models first
This comparison is a model-family guide unless you choose a specific Anker SKU. The Baseus FC11 name is also used for variants with different capacity or output, so confirm that the listing is for the 20,000 mAh, 45 W E0031100. The relevant Anker examples span 30 W, 45 W, 87 W and higher-output products.
| Model | Capacity and maximum output | Cable and ports | Published mass |
|---|---|---|---|
| Baseus EnerFill FC11 E0031100 (US page) | 20,000 mAh; 45 W | Two integrated USB-C cables; USB-C and USB-A connectors; four ports in the specifications | Approx. 362 g |
| Anker Power Bank (20K, 30W), A1384 | 20,000 mAh; up to 30 W USB-C output, 18 W USB-A output; up to 24 W total output under the stated total-output condition | Two USB-C ports and one USB-A port | 462 g |
| Anker Power Bank (20K, 87W, Built-In USB-C Cable), A1383 | 20,000 mAh; up to 87 W total output (65 W + 22 W) | Built-in USB-C cable and ports | Approx. 430.91 g |
| Anker Zolo 20K 45W (EU page) | 20,000 mAh; 45 W | Dual built-in USB-C cables | Not stated on the cited EU page |
| Anker Prime 20K/220W edition (official page) | 20,100 mAh; up to 220 W total output | Not stated here; confirm the exact regional SKU | 510 g |
Specifications above come from the manufacturers’ product pages, accessed October 4, 2026, rather than independent testing. The Prime 20K/220W listing is a distinct product; Anker also has a separate 200 W support-page model with a different published mass of 545 g. Do not treat either as representative of every Anker 20,000 mAh bank.

Maximum wattage is a ceiling, not a promise that every device will charge at that rate. Check the target device’s supported charging standard and input limits, then compare them with the bank’s output profile. Actual charging depends on the device, protocol, cable, charge state, temperature, and whether other devices are connected.
#1 Best Overall
- Ultra-Slim & Pocket-Ready Portable Charger: Designed for everyday carry, this compact power bank measures just 4.3 × 2.6 × 0.7 inches and weighs only 7 oz, making it easy to slip into a pocket or bag. Despite its slim profile, it packs a 10,000mAh high-capacity battery, delivering up to 1.8 full charges for iPhone 17. Ideal for commuting, work, and travel.
- 45W High-Speed Charging: Delivering up to 45W fast charging, this portable phone charger keeps your devices energized in no time. It boosts an iPhone 17 Pro to 67%, and a Samsung S25 Ultra to 60% in just 30 minutes. With 30W rapid input, the portable power bank also recharges quickly and supports pass-through charging for ultimate convenience.
- Dual Built-in USB-C Cables: Experience clean, clutter-free charging with two integrated USB-C cables that eliminate the need for extra cables. Both cables of the USB-C power bank have been tested to withstand over 10,000 pulls and bends. Power up your devices instantly and lastingly by this portable charger USB-C, or share a cable with someone else when needed.
- Four-in-One Charging Convenience: Charge four devices simultaneously in emergencies with a combination of built-in USB-C1 cable, built-in USB-C2 cable, USB-C port, and USB-A port. This all-in-one iPhone portable charger supports smartphones, tablets, earbuds, drones, gaming consoles, and other USB-powered devices.
- Cool, Safe & Travel-Ready: Engineered with Baseus NTC temperature control, the power bank for iPhone maintains cool operation even during high-speed charging. Multiple safety protections guard against overcurrent, overvoltage, overheating, over-discharge, and short circuits. With airline-approved capacity and a compact build, it’s a dependable portable battery pack and travel companion for flights, road trips, and daily use.
- Phones and smaller accessories: A 30 W model may already meet a phone’s practical input limit; a higher bank rating does not necessarily make that phone charge faster.
- Tablets, handheld consoles, or laptops: Check the device maker’s recommended power and charging compatibility. The FC11 is rated up to 45 W, while the A1383 lists up to 65 W from its USB-C cable or port. These ratings alone do not establish which will charge a particular laptop faster.
- Multiple devices: Consider total shared output, not just the largest single-port number. The Anker A1384’s listed total is up to 24 W under its specified total-output condition, despite its individual port ratings. Baseus says FC11 output may be shared when multiple devices are charging.
Compare built-in cables with the ports you need
The FC11 has two integrated USB-C cables as well as ports, which can reduce the need to pack separate leads for USB-C devices. The A1384 instead offers three discrete ports, useful if you prefer choosing your own cables or need USB-A. The A1383 combines a built-in USB-C cable with ports. Anker’s EU-listed Zolo 20K 45W is closer to the FC11’s dual-cable design, but regional versions should be checked before treating it as a like-for-like alternative.
Count the connectors required for your regular devices. Built-in cables are convenient when their connector type and reach suit you; discrete ports offer flexibility with cables you already own. Also check how many devices can be connected at once and the maker’s output-sharing rules.

Weigh capacity, dimensions, and carrying burden
All these examples are near the 20,000 mAh class, but the label is nominal stored capacity—not a guarantee of a fixed number of phone recharges. Comparable independent usable-energy tests or controlled recharge counts for these exact models are not established here.
The Baseus page lists dimensions of 1.26 × 4.37 × 2.67 inches and an approximate mass of 362 g. Anker lists the A1384 at 153.4 × 71.6 × 28.1 mm and 462 g; the A1383 measures 15.75 × 7.35 × 2.6 cm and weighs approximately 430.91 g. These are manufacturer figures, not same-lab measurements. Check the listing for the exact version, and consider whether the cable convenience justifies the space and weight in your bag.

Check market-specific terms before buying
The Baseus specifications cited are from its US page, while the dual-cable Anker Zolo page is for the EU market. Availability, product versions, included accessories, warranty terms, and seller listings can vary by country. Verify the precise model number and local terms at the seller before purchase; the available manufacturer pages do not establish a current cross-market price comparison or comparable recharge-time result.
Do not assume a general airline approval from a seller claim. Check the Wh marking on the exact unit and the current requirements of the airline and itinerary.
Quick Recap
Choose by your actual use
- Prioritize a lighter carry and two built-in USB-C leads: The FC11’s listed 362 g and dual cables are relevant advantages to compare, if you are buying the 20,000 mAh, 45 W E0031100.
- Prefer a straightforward port-based layout: The A1384 has two USB-C ports and one USB-A port, but its listed maximum USB-C output is 30 W and its total-output limit is specified separately.
- Need a built-in cable and more rated output: The A1383 lists 87 W total, including up to 65 W from its USB-C cable or port; check whether the target device supports that profile.
- Considering a 45 W Anker with dual cables: The EU Zolo listing is a plausible feature-class peer, but confirm the regional SKU and terms.
- Looking at an Anker Prime: Compare its exact model and output tier rather than assuming it is an equivalent FC11 alternative.
