Great deals on 2-in-1 hybrid charger/power bank

Power banks are not just power banks now. There are offerings from Anker that are both: a power bank and a wall adapter. This makes them a great accessory for your travel bag, as you'll have one less thing to carry around. These devices usually feature a 5,000 to 10,000mAh battery, which provides enough juice to top up even the best mid-range Android phones with their beefy battery at least once.


Q: What capacity power bank should you buy?

The answer depends on how many devices you carry when traveling. If you want to charge your MacBook or your tablet, phone, and watch many times over while on the go, you'll need a power bank with a 20,000mAh+ capacity. A portable battery pack with a smaller capacity won't be enough for this job.

Q: Is Prime Day a good time to buy a new power bank?

Yes! Many of the best power banks are discounted to nearly their lowest price for Amazon's shopping event, making it a perfect time to buy them.

Q: How should you store your power bank when it won't be used for the long term?

Charge the portable battery pack to at least 70-80% before storing it for an extended period of inactivity. You should also keep them in a cool, dry place and avoid exposure to direct sunlight or high humidity.
