Anker

Anker Prime 27,650mAh Power Bank (A1340)

A roughly 100Wh USB power bank with a maker-listed 250W combined output ceiling and a 140W maximum output claim; useful when comparing multi-device USB charging against larger AC stations.

Model
A1340
Capacity mah
27650
Energy wh
99.54
Energy note
99.54Wh is listed on Anker New Zealand product page for A1340.
Output
Manufacturer lists 250W multi-device output and up to 140W output; these are product-level and maximum-output figures, not a promise of 250W from one port.
Input
USB-C input up to 140W is listed; Anker notes a 170W recharge configuration uses both USB-C ports and a 140W charger.
Market source
Official UK product page plus official New Zealand listing for the energy rating.

Consider the tradeoffs

  • USB output depends on the device and charging protocol; the headline combined wattage does not establish a particular phone or laptop charge rate.
  • At 99.54Wh, this is a USB power bank rather than a household AC station; check current carrier rules before flying with any battery.

Questions worth testing

  • Which devices will be connected at the same time?
  • What USB-C charging protocol and input wattage does each device accept?
  • Is your priority travel weight, simultaneous charging, or stored energy?

Scope & unknowns

  • No device charging, runtime, heat, durability, or travel-rule test was performed.
  • The 250W and 140W values are manufacturer product claims; actual output varies with port use and compatible devices.
  • Airline or jurisdiction rules are not assessed here.

UGREEN

UGREEN Nexode Power Bank 25,000mAh 200W (35525)

A 90Wh three-port USB power bank with separately listed port ceilings and a 200W product headline; the per-port and combined limits should be checked against the intended device mix.

Model sku
35525
Capacity mah
25000
Energy wh
90
Ports
Two USB-C and one USB-A are listed.
Output
Manufacturer lists up to 140W on USB-C 1, 100W on USB-C 2, 27W on USB-A, and 200W headline output; concurrent output is subject to the product power-allocation table.
Weight g
592
Market source
Official UGREEN UK product page.

Consider the tradeoffs

  • The 140W, 100W, and 27W port maxima should not be added as if all can occur at once; the product headline is the combined ceiling.
  • At 592g, it is a relatively substantial power bank; it has no AC outlet listed on the reviewed page.

Questions worth testing

  • Which laptop or phone will use each port?
  • Does the device need a specific USB PD or PPS profile?
  • Will one device charge alone or several devices together?

Scope & unknowns

  • No independent output, runtime, or weight test was conducted.
  • Use the manufacturer’s current port-allocation table for simultaneous loads.
  • Local availability and price are not recorded.

Baseus

Baseus Blade 2 Smart Power Bank 65W 12,000mAh (P10063801323-00)

A 46.44Wh slim USB-C power bank with two USB-C outputs and a 65W single-port ceiling; the page describes a 45W plus 20W split when both outputs are used.

Model sku
P10063801323-00
Capacity mah
12000
Energy wh
46.44
Ports
Two USB-C ports.
Output
Up to 65W from one port; manufacturer lists 45W + 20W when both ports are used.
Input
Up to 60W input is listed.
Weight g
339
Market source
Official United States Baseus product listing.

Consider the tradeoffs

  • The two-port split is lower than the one-port maximum.
  • The United States listing displayed sold out during the page check; stock can change and is not a purchase recommendation.

Questions worth testing

  • Will one USB-C device or two be connected?
  • Does the device accept up to 65W through its USB-C charging input?
  • Is a flatter pack worth a lower energy capacity than 90–100Wh alternatives?

Scope & unknowns

  • No independent output, runtime, device compatibility, or availability check beyond the dated page read was performed.
  • The listing’s stock state is a dated page snapshot, not a durable availability fact.

UGREEN

UGREEN Portable Power Station 48,000mAh 300W (25286)

A 153.6Wh, 1.637kg USB battery with up to 300W listed total output and multiple USB ports; the reviewed product specification does not list an AC outlet.

Model sku
25286
Capacity mah
48000
Energy wh
153.6
Chemistry
LiFePO4, as stated by manufacturer.
Ports
Five USB ports are listed: three USB-C and two USB-A.
Output
Up to 300W product-level output; USB-C1 up to 140W, USB-C2/C3 up to 100W each, USB-A up to 22.5W each, subject to shared-output limits.
Weight g
1637
Market source
Official UGREEN UK product listing.

Consider the tradeoffs

  • The listing uses “power station” wording, but the reviewed specifications show USB outputs and no AC outlet; do not treat it as equivalent to an AC inverter station.
  • The 300W headline is not a per-port rating.

Questions worth testing

  • Do you need USB charging only, or a mains AC socket?
  • Can the load use USB-C PD, and what wattage does it require?
  • Does a 1.637kg pack fit the intended carry use?

Scope & unknowns

  • No independent capacity, cycling, or output measurement was performed.
  • No AC output was found in the reviewed official specifications; confirm the exact local product revision before purchase.
  • Manufacturer cycle-life statements are not independently tested here.

EcoFlow

EcoFlow RIVER 3 Plus (EU listing)

A 286Wh LiFePO4 AC power station with a 600W rated-output claim and optional expansion to 858Wh; X-Boost is a separate manufacturer mode and should not be treated as the standard rated output.

Base capacity wh
286
Expanded capacity wh
858
Expansion
Manufacturer lists EB300 and EB600 add-on batteries; these are separate accessories.
Ac output
600W rated output; manufacturer separately lists 1200W X-Boost.
Ac outlets
Two rear AC outlets are listed on the EU product page.
Battery chemistry
LiFePO4; manufacturer lists 3000 cycles to 80% capacity.
Weight kg
4.7
Manufacturer runtime examples
The page estimates up to 35 hours for a 3W Wi-Fi router and at least 21 minutes for a 600W computer; these are maker estimates, not independent runtime measurements.
Market source
Official EcoFlow Europe product page.

Consider the tradeoffs

  • At 4.7kg, it is a different carry class from USB power banks.
  • X-Boost is a maker-labeled operating mode; check appliance requirements against the standard rated output and the exact local manual.
  • The EU listing displayed sold out at the time checked.

Questions worth testing

  • What is the appliance’s rated and start-up wattage?
  • How many hours of operation are needed?
  • Is an AC outlet required, or would USB output be enough?
  • Which local-market voltage and outlet version is needed?

Scope & unknowns

  • The example runtimes are manufacturer estimates and should not be generalized to other loads.
  • No independent UPS, output, or runtime test was performed.
  • Verify the exact local AC voltage, frequency, plug, and outlet version before using an appliance.
  • Page availability can change.

BLUETTI

BLUETTI Elite 100 V2 (US version)

A 1,024Wh US-market station with 1,800W rated AC output at 120V; the advertised 2,700W lifting mode is a distinct manufacturer claim, not the normal rated output.

Capacity wh
1024
Rated ac output
1800W at 120V / 15A, as listed by the manufacturer.
Lifting power
Manufacturer advertises 2700W lifting power; its exact supported load conditions must be checked in the manual.
Weight kg
11.5
Outlets
Manufacturer lists 11 outlets.
Connectivity
Wi-Fi and Bluetooth are listed.
Market source
Official United States BLUETTI product page.

Consider the tradeoffs

  • At 11.5kg, this is a larger backup/travel station rather than a small carry bank.
  • The 120V US output is not a match for every region or 230V appliance.
  • Lifting power is a separate maker mode and does not replace the 1800W rated output.

Questions worth testing

  • Will the load operate on 120V?
  • What are the load’s running watts and start-up surge?
  • How long must it run, and can the station’s weight be accommodated?

Scope & unknowns

  • No independent output, capacity, runtime, or lifting-mode test was performed.
  • Do not infer suitability for 220–240V devices from the US product page.
  • Confirm the exact model and outlet configuration for the intended market.
