Anker 737 vs UGREEN Nexode 130W: Laptop Power Bank Guide
Both are three-port USB-C laptop power banks with status displays. Anker offers the larger cell capacity and higher single-port ceiling, while UGREEN uses a smaller 72 Wh pack and a 100-watt primary port.
Best for
Laptop and tablet owners choosing a high-output portable battery by exact port limits, capacity, charging input and device compatibility.
Probably not for
A guaranteed laptop recharge count, unrestricted airline travel, wireless charging, or anyone whose device and cable cannot negotiate USB-C Power Delivery.

Anker 737 Power Bank (PowerCore 24K)
Anker 737 is a 24,000 mAh three-port power bank with two USB-C connections, one USB-A connection and a digital status display. Either USB-C port can provide up to 140 watts to a compatible device, and the power bank accepts up to 140 watts of USB-C input with a suitable charger and cable.
Pros
- Its 24,000 mAh cell rating is larger than the UGREEN pack.
- A compatible USB-C port can reach a 140-watt single-port output and a 140-watt input ceiling.
Cons
- The larger cell pack is about 22 ounces according to the exact Amazon listing.
- The highest output and input modes require compatible devices, chargers and e-marked cables.
Who it’s for: Choose it when 140-watt single-port delivery, faster supported input or the larger capacity addresses a real laptop routine. Pass if a smaller 72 Wh pack is easier to carry and 100 watts covers the device.

UGREEN model PB721 is a 20,000 mAh, 72 Wh power bank with a 100-watt USB-C1 port, 30-watt USB-C2 port, 22.5-watt USB-A port and TFT display. UGREEN specifies up to 65 watts of input and uses the 130-watt name for its supported combined output configuration.
Pros
- The published 72 Wh rating makes the stored-energy figure explicit for travel planning.
- Its display, two USB-C ports and one USB-A port cover the same broad connection mix as Anker.
Cons
- Its primary single-port maximum is 100 watts, not the 130 watts in the product name.
- Its 65-watt input ceiling is below Anker’s supported 140-watt input.
Who it’s for: Choose it when 100-watt laptop output is sufficient and the smaller-capacity design suits the bag. Pass if the laptop genuinely needs more than 100 watts from one port or rapid high-power refilling matters.
Check UGREEN Nexode Power Bank 20000mAh 130W on Amazon Paid linkThe headline wattages describe different things
Anker publishes up to 140 watts from either USB-C port when one compatible device is connected. UGREEN publishes 100 watts from USB-C1, 30 watts from USB-C2 and 22.5 watts from USB-A, while the 130-watt product name refers to a supported combined-output arrangement. A 130-watt total is therefore not a 130-watt laptop port. Start with the maximum on the exact port the laptop will use, then examine what remains for a phone or tablet.
USB-C Power Delivery is negotiated. The source, cable and receiving device must share a supported voltage and current profile before the highest mode is available. A basic cable can reduce the ceiling, and some laptops accept less power while operating or insist on a proprietary adapter for full performance. Check the laptop manual and cable marking. This comparison does not claim either pack will make an unsupported computer charge at its label maximum.
Capacity labels do not equal energy delivered to a laptop
Anker lists 24,000 mAh, while UGREEN lists 20,000 mAh and 72 Wh. The milliamp-hour figure is based on the internal battery-cell voltage, not the laptop battery voltage. Conversion to a USB output voltage consumes energy, as do the display, control electronics, cable resistance and heat. Dividing one advertised mAh figure by a laptop battery figure can therefore produce an unrealistic recharge count.
Watt-hours are the more useful travel and energy-planning unit when both products provide them, but they still do not promise usable output after conversion. Estimate with margin and treat manufacturer capacity as a nameplate specification rather than a measured result. Anker’s larger cell rating should offer more stored energy under comparable definitions, but this guide did not conduct a discharge test and does not assign either product a laptop-charge count.
Input speed matters only with the right wall charger
Anker supports up to 140 watts of USB-C input, while UGREEN specifies up to 65 watts. Those ceilings can make a meaningful difference when the battery is refilled between trips, but neither box creates that input power by itself. The wall charger, cable and outlet must support the required Power Delivery profile. A common phone adapter will charge more slowly even if it physically fits the USB-C socket.
Do not compare recharge claims unless the test conditions use the same starting level, charger, cable, temperature and feature settings. The status screens can help with planning by showing charging information, but a live estimate can change as negotiation and temperature change. For overnight charging, a lower input ceiling may be irrelevant. For a short turnaround between meetings, compatible high-power input can be the more important Anker advantage.
Three ports require an allocation plan
Both products include two USB-C ports and one USB-A port, but output is redistributed when several devices are connected. The laptop should normally use the designated high-output USB-C port. Plugging or unplugging another device can trigger a new power negotiation, and a low-power accessory does not guarantee that the laptop keeps the exact same allocation. Consult the current port-allocation diagram for the chosen model before building a three-device setup.
USB-A is useful for older cables, but it is not a substitute for the primary USB-C laptop connection. Avoid loose adapters and do not cover the pack while it is handling high power. Stop using a battery that is swollen, damaged, wet or unusually hot, and follow the maker’s storage and recycling directions. A high watt number is not a reason to charge on a bed, in direct sun or inside an unventilated pouch.
Choose by the laptop, cable and trip rules
Choose Anker 737 when a supported 140-watt laptop mode, up to 140-watt input and the larger 24,000 mAh cell rating justify the extra pack. Choose UGREEN PB721 when a 100-watt main port meets the computer’s needs and a 20,000 mAh, 72 Wh design is the better fit. If the target laptop accepts 65 watts, buying a larger output number will not force it to take more power.

Airline and security rules can vary by carrier, route and jurisdiction, and spare lithium batteries normally belong in carry-on baggage under applicable limits. Check the current carrier rules before travel. No airline approval, runtime, recharge count, price, stock status or charging-speed test is claimed here.
