At ZDNET, we’re all about putting tech to the test to actually see which phone has the best battery life or which robot vacuum has the best pickup performance. And when we tested 10 different portable power stations in our lab, one was the clear winner for the small-sized category: the Oupes Mega 1. This model was the most efficient for small portable power stations (devices with 600-1,100 Wh). And right now, it’s $120 off for Amazon’s Prime Day sale this week.

In our lab testing, the power stations with higher watt-hours per time charged were the top performers. The Oupes Mega 1 took only 21 minutes to charge to 100% in its group, while still retaining 1024 watts per hour. It beat other small-sized power stations from brands like Anker, EcoFlow, and Bluetti. 

Aside from its efficiency, the Oupes Mega 1 offers a range of power outputs, including a bank of four AC outlets, USB-C and USB-A ports (100W and 18W maximum, respectively), a 12V car outlet, and two DC5521 ports.

Plus, it weighs just under 30 pounds, making it compact and portable enough for travel, camping, etc. 

I recommend this portable power station if you want efficient energy performance that will keep all kinds of devices charged up. And with this deal, there’s an even better reason to buy the Oupes Mega 1

How I rated this deal 

According to our ZDNET deal-rating system, this 22% off deal is a 3/5 deal. You get $120 off one of the best-performing small portable power stations on the market, so I think it’s a deal worth snagging. 

This year, Amazon set its annual Prime Day event a little earlier, bumping it up into June instead of its usual July slot. The Prime Day sales event is officially from June 23-26, but you can expect sales prior to and even after the event.

Running a manufacturing business is a constant balancing act between the workshop floor and the balance sheet. Right now, that balance is under real pressure.

The current surge in fuel prices is flowing straight through jobs — via fuel surcharges, higher freight, and rising costs for materials like concrete, plastics, copper, and piping. Costs aren’t rising in isolation; they’re compounding across every job.

It’s this kind of pressure that can expose hard truths about profitability for small businesses, similar to what one growing Australian fabrication business found when examining their balance sheet more closely. Despite strong demand and a consistently full workshop, profitability wasn’t keeping pace with revenue. Hidden margin leaks across labour and materials were quietly eroding results.

By connecting operational job costing with financial reporting using Gojee, Xero, and Syft, the business gained the real-time visibility it needed to stop the leaks and recover more than $165,000 in annual margin.

The challenge: Visibility beyond the spreadsheet

The business relied on Xero for its accounting, but like many manufacturers, its operational job costing was tracked separately in spreadsheets and workshop records.

This created a significant data disconnect. Leadership could see their overall financial results, but they couldn’t clearly identify which specific jobs were driving profit and which were costing the business money.

When CFO advisor Amanda Fisher stepped in to assist the finance team, she used Syft to analyse Xero data and uncovered a startling insight. The business had a target gross margin of 32%, but was actually achieving only 29.7%. That gap represented nearly $180,000 in lost profit every year.

“As a CFO, the key to decision-making is real-time data. Syft is perfect for visuals that help business owners understand the big picture. But in manufacturing, the devil is in the detail. That’s where Gojee helps uncover hidden margin leaks and bridge the gap between the factory floor and finance.” 

– Amanda Fisher, Xero accountant & CFO advisor

The solution: A connected tech stack

To bridge the gap, Amanda introduced Gojee to manage job costing and workflows directly alongside Xero. This created a seamless flow of data:

  • Gojee captures real-time labour hours and material purchases on the factory floor.
  • Xero handles the financial transactions, bills, and invoicing.
  • Syft translates that data into visual dashboards for margin analysis and trend tracking.

What the data revealed

Once the business had real-time visibility, three common profit leaks emerged:

  • Labour rework: One project quoted for 720 hours actually took 845 hours, reducing the margin by over $10,000. Annually, labour overruns cost the business approximately $95,625.
  • Materials price variance: Quoting based on estimated costs rather than confirmed supplier invoices led to $66,000 in annual margin erosion.
  • Low-margin jobs: Analysis showed that smaller, complex custom projects often disrupted workshop productivity. One $75,000 project achieved only an 18% margin, far below the 30% expectation.

The results: From reactive to proactive

Armed with these insights, the company adjusted its quoting strategy and began prioritising higher-margin work. Within 12 months, the results were transformative:

Metric Before After
Gross margin 29.7% 31.8%
Annual profit $165K+ recovered

Today, the business doesn’t just work harder; it works smarter. The machines and the team haven’t changed, but the visibility has. By moving from reactive reporting to proactive decision-making, they have turned a busy workshop into a highly profitable one.
