Frequently Asked Questions (FAQs)
1. Is Samsung 45W power bank worth buying in Kenya?
Yes, if you own flagship devices (Galaxy S22/S23/S24/S25 Ultra, iPhone 15, iPad Pro) and value fast charging. At KSh 6,499 from authorized dealers, it’s a premium investment that delivers wall-charger speeds on-the-go. Skip it if you have budget phones that only support 15W charging – you won’t benefit from the 45W output.
2. Can it charge my laptop?
Yes, but with limitations. It charges 13″ laptops like MacBook Air M2, Dell XPS 13, and HP Spectre x360 effectively. Larger 15-16″ laptops requiring 60W+ will charge very slowly or only when turned off. Best for emergency top-ups, not full charges.
3. How long does it take to recharge the power bank itself?
With a 25W Samsung fast charger: 1 hour 50 minutes. With a standard 18W charger: 2.5-3 hours. With a 15W charger: 3.5-4 hours. The power bank supports 25W input charging, so invest in a 25W charger for fastest recharge times.
4. Does wireless charging work with phone cases?
Yes, the 10W wireless charging works through cases up to 5mm thick. Thin silicone, TPU, and plastic cases work perfectly. Remove thick leather cases, wallet cases, metal cases, or cases with magnetic attachments as these block wireless charging.
5. Can I take it on planes from Kenya?
Yes. At 74Wh, this power bank is under the 100Wh limit set by IATA, FAA, and KCAA. You can carry it in hand luggage on Kenya Airways, Ethiopian Airlines, Emirates, and all international carriers. It must be in carry-on luggage, NOT checked bags.
6. What cables do I need to buy separately?
The power bank doesn’t include cables. You need: (1) USB-C to USB-C cable (5A rated, KSh 800-1,500) for fast charging Samsung/Google phones, (2) USB-C to Lightning cable (KSh 1,200-2,000) for iPhones 14 and older, (3) Optional: USB-A to USB-C cable for older devices.
7. How many years will this power bank last?
Samsung guarantees 500 charge cycles with 80% capacity retention. With daily charging, that’s 1.5 years before noticeable degradation. Light users (2-3x per week) get 3-4 years. Lithium Polymer batteries last longer than cheaper Lithium-Ion competitors. Store at 50-80% charge when not used for months.
8. Will it damage my phone battery with fast charging?
No. Samsung’s PPS (Programmable Power Supply) technology communicates with your phone to deliver exactly the right voltage and current. The power bank automatically slows charging above 80% to protect battery health. Modern smartphones have built-in charging controllers that prevent damage even with daily fast charging.
