Super Power Electronics & Beauty Supplies: The Complete 2026 Guide
Super Power Electronics & Beauty Supplies on Thames & Church Street is St. John's go-to shop for phone cases, LED strips, and beauty essentials. Complete 2026 guide.
If you've spent any time in downtown St. John's, you've walked past Super Power. It sits at the busy intersection of Thames and Church Streets, right in the commercial heartbeat of the capital. Locals know it simply as "Super Power." Visitors discover it by accident and come back on purpose.
The store has been a fixture in St. John's for decades. That kind of longevity on a small Caribbean island means something. It means the store delivers what people need, at prices that work for island life, in a location that couldn't be more convenient. Whether you're a cruise passenger who cracked your phone screen on day one, a local who needs an LED strip for a home project, or a visitor who forgot her favourite mascara, Super Power has a good chance of solving your problem before you reach the end of the block.
This guide covers everything: what the store actually stocks in 2026, how it compares to RadioShack, TechShop, and ACT, what the staff can help you find, the exact opening hours, and practical tips for getting the most out of your visit.
Where Is Super Power in St. John's?
Super Power is located at the corner of Thames Street and Church Street in St. John's, the capital of Antigua. The address is Thames, Church Street, St. John's, and the phone number is +1 268-462-1890.
The location is genuinely central. Heritage Quay, Antigua's main cruise terminal, sits directly on Thames Street. That means cruise passengers who step off the ship are a short, flat walk from the store. No taxis required. No map needed. Just head up Thames Street from the pier toward the town centre, and Super Power is on your right.
For visitors staying at hotels around Dickenson Bay or the west coast, the drive into St. John's takes around 15 to 20 minutes. Parking near Thames and Church Street can be tight on busy cruise-ship days, so arriving early makes life easier.
The store sits at the centre of St. John's parish, Antigua's commercial hub with nearly 700 businesses. It's surrounded by banks, pharmacies, and other retail stores, which makes it easy to combine a Super Power visit with other errands.
What Are Super Power's Opening Hours?
Super Power is open Monday to Friday from 8:00 am to 5:00 pm, with extended hours on Friday until 6:00 pm. Saturday hours run 8:00 am to 5:00 pm. The store is closed on Sundays.
Those hours matter if you're planning around a cruise ship schedule. Most ships dock in the morning and depart by early evening. Super Power's early 8:00 am opening means you can visit right after the ship docks, before the heat of the day and before crowds build up in the rest of downtown.
Friday is the best day to visit if you need the most time. The extended closing hour gives you an extra window, especially if you're arriving on a Friday afternoon ship or picking up supplies before the weekend.
What Does Super Power Actually Stock?
Super Power carries a broad mix of consumer electronics and beauty supplies. It's not a specialist electronics retailer like ACT or a pure beauty store like a pharmacy cosmetics section. It's a practical variety retailer with an unusually useful combination of products.
Electronics and Tech Accessories
The tech side of the store covers the everyday essentials that people actually need on a Caribbean island:
Smartphones and mobile devices. Super Power carries smartphones and can source specific models via staff, who have access to additional stock held in storage. If you're looking for a particular phone or model and can't see it on the shelf, ask. Locals consistently report that staff will check the back for you.
Phone cases and screen protectors. This is one of the store's strongest categories. Cases for current iPhone and Samsung models are stocked on an ongoing basis. Tempered glass screen protectors have been a staple product since at least 2015, when the store was actively posting about stock for Samsung Note and Galaxy S-series phones. If you've landed in Antigua with a vulnerable screen and no case, Super Power is the fastest fix.
LED lighting strips. LED strips for home use are a popular product line. The Caribbean home improvement market has a steady appetite for LED lighting, and Super Power has kept this category stocked consistently.
Televisions. The store has historically carried budget-friendly flat-screen TVs in the 24-inch range, with EC$-denominated pricing. At an exchange rate of roughly EC$2.70 to US$1, EC$995 for a 24-inch Samsung TV converts to around US$370 at street rates. Exact current stock varies, so calling ahead for large-item availability is worthwhile.
Stereo and audio products. Speakers, audio accessories, and related items have been part of the range. The store has run outside sales specifically for stereo items in the past, clearing stock at reduced prices.
Cables, chargers, and accessories. The bread and butter of any electronics shop. If you need a USB charger, a cable, headphones, or a power bank, Super Power is a quick stop before you need any of those items on a beach.

Beauty Supplies and Cosmetics
The beauty side of Super Power is equally important and often overlooked by visitors who assume it's primarily a tech store. The name tells you exactly what it is: half electronics, half beauty.
The beauty supplies section stocks:
Cosmetics. Foundation, lipstick, mascara, eyeshadow, and related makeup products. The range covers both budget and mid-market brands. This is particularly useful for cruise passengers who arrive without something they needed, or for locals looking to pick up beauty basics without travelling to a dedicated beauty store.
Skincare and personal care products. Moisturisers, cleansers, and body care items form part of the personal care range. On a Caribbean island where sun exposure is a daily reality, having sunscreen and after-sun products available in a central, accessible location matters.
Hair care products. Shampoo, conditioner, and hair styling products are stocked alongside grooming accessories. The beauty supply community in St. John's is well served by several dedicated salons and beauty shops, but Super Power offers convenience for quick purchases without needing to go to a specialist store.
Grooming accessories. This covers a range of tools and accessories for both men and women, from brushes and combs to nail care products.

How Does Super Power Compare to RadioShack, TechShop, and ACT?
This is the practical question most people actually want answered. Here's an honest breakdown.
Super Power vs. RadioShack. RadioShack operates two stores in St. John's: one at Woods Centre on Friars Hill Road and one downtown at Market Street and St. Mary's Street. RadioShack is part of the ACT/Unicomer group and carries a formal consumer electronics range including smartphones, tablets, Bluetooth speakers, power banks, batteries, and LED lighting. It's a structured retail experience with brand-consistent presentation. Super Power is independent and more eclectic. It covers similar accessory categories but adds beauty supplies, which RadioShack does not carry. RadioShack has slightly more retail polish; Super Power has a more varied product mix and a location that's closer to the cruise terminal.
Super Power vs. TechShop. TechShop Antigua is the island's newest dedicated tech accessories retailer, based at Town Park Plaza on Friars Hill Road. It opens later (10:00 am) and closes later (8:00 pm), which suits evening shoppers. TechShop focuses on tech accessories, cables, Bluetooth products, gaming accessories, and repairs. It doesn't carry beauty supplies. Super Power opens earlier (8:00 am), is closer to downtown, and has the beauty category that TechShop lacks. For pure tech accessory shopping in 2026, TechShop has a modern format; for a central downtown location with beauty supplies included, Super Power has the edge.
Super Power vs. ACT. ACT (Antigua Computer Technology) is the island's most comprehensive technology company, founded in 1989 and serving businesses and consumers with laptops, computers, IT services, cybersecurity, and networking. It's an enterprise-level tech provider, not a casual walk-in shop. Super Power is for everyday purchases: cases, chargers, beauty items, accessories, small electronics. The two don't really compete. If you need a laptop repaired or an IT network set up, ACT is the answer. If you need a phone case and a mascara before your afternoon excursion, Super Power is where you're headed.
The bottom line: Super Power occupies a specific and useful niche. It's the most conveniently located store for cruise passengers and downtown visitors, it combines two product categories that no other single store covers, and it opens early enough to serve the morning rush.
If you're browsing all the options available in St. John's, the full retail and shopping category on AntiguaSearch lists over 129 businesses across the island.
The Secret Weapon: Ask the Staff
One of the most consistent pieces of advice from longtime Super Power customers is simple: ask the staff.
One local reviewer put it plainly: "If you are looking for an item and can't seem to find it, just ask one of the customer service reps and they will, more often than not, point it out or get it from storage." That detail is worth knowing. The shop floor doesn't always represent the full inventory. The back of the store holds additional stock, and staff who know the place well can retrieve items that aren't on display.
This is particularly useful for:
- Specific phone models you can't see on the shelf
- Particular case sizes or styles
- Beauty products that may have sold down on the display but are still available
The store's Facebook page, with over 2,600 followers, is another useful resource. Staff post promotional sales, new arrivals, and stock updates. Following the page before your visit is a quick way to find out what's currently on offer and whether any sale events are running.
If you run a retail business in St. John's and want to grow your online visibility the way Super Power has built its local following, adding your listing to AntiguaSearch puts your business in front of locals and visitors across the island.
Tips for Getting the Most from Your Visit
Go early in the week. The store recommends weekday visits to avoid weekend crowds. Monday through Thursday mornings, just after the 8:00 am opening, are typically the quietest.
Call ahead for large items. Televisions and stereo equipment have variable stock levels. A quick call to +1 268-462-1890 before you visit saves a wasted trip if you're looking for a specific screen size or product.
Watch for outside sales. Super Power has historically run outdoor sale events with half-price discounts on selected items. These are announced on the Facebook page. If you're on the island for a few days, checking the page for sale announcements can turn up genuine deals.
Bring EC$ for smaller purchases. US dollars are widely accepted in the Heritage Quay area and at larger stores, but having Eastern Caribbean dollars on hand for smaller purchases is good practice. The official currency exchange rate is EC$2.70 to US$1.
Combine with other downtown stops. Super Power's location at Thames and Church Street puts it within easy walking distance of most of downtown St. John's. A visit to Super Power pairs naturally with a trip to the public market, the Museum of Antigua and Barbuda, or the restaurants and cafes along Redcliffe Quay.
Who Is Super Power Best Suited For?
Cruise passengers arriving at Heritage Quay who need a phone case, a charger, or a quick beauty top-up. The walk from the pier takes just a few minutes along Thames Street.
Short-stay visitors at hotels who need everyday essentials without a long taxi ride to a mall.
Locals and long-term residents who value the combination of tech accessories and beauty supplies in a single, centrally located stop. The store has earned a loyal local following over decades of operation.
Expats and NDR visa holders who want a familiar-format convenience store for phone accessories and personal care products while they get settled in Antigua.
Super Power isn't the island's largest electronics retailer or its most comprehensive beauty store. It's something more useful: a well-stocked, well-located, long-established shop that covers two product categories at once, opens early, and has staff who know their inventory well enough to go looking in the back.

Conclusion
Super Power Electronics & Beauty Supplies is one of those St. John's businesses that earns its place by being consistently useful. A decade from now it will probably still be on Thames and Church Street, serving the same mix of locals, expats, and visitors who've made it a downtown staple.
Three things to remember:
- The store opens at 8:00 am Monday to Saturday, which makes it ideal for cruise passengers who want to shop before the midday heat.
- The dual electronics and beauty format is unique among downtown St. John's retailers. No other single store covers both categories in the same footprint.
- If you can't find what you need on the shelf, ask. The staff can often retrieve items from storage that aren't on display.
