Deals on portable chargers
Prices on portable chargers range quite a bit, but it’s a good idea to have one just in case you need to recharge a device and there are no power outlets available. It’s also beneficial to have one with large enough charging capacity to charge your most important devices!
“mAh” means milliampere hour and it measures electric power over time. Portable chargers range from 3000mAh and up, but the more capacity you have, the more you’ll be able to charge. To get a rough estimate of how much you’ll be able to charge using an external power bank, divide the mAh of your power bank by the mAh of your device battery.
To give an example, an iPhone 4 has a 1420mAh battery, while an iPhone 7 Plus has a 2900mAh battery. A 6000mAh power bank could charge an iPhone 7 Plus about two times, and an iPhone 4 about 4 times — but this can be lessened by the age and charge of the current battery and also the current tasks of the device being charged.
A 15000mAh battery could charge most smartphones about 4 times. These 15000mAh portable charger are all under $15!

For the chargers available at Walmart, you could select in-store pickup to dodge the shipping fee if your order is below $35. eBay also have some screaming deals on 15,000mAh portable chargers as low as $5, but if you buy one, you’ll likely have to wait a bit since they ship from Asia.
If you don’t need a charger with such high capacity, check out this RAVPower 12000mAh external power bank for $16, or this Auto Drive 2200mAh USB portable power bank for $3. Before you buy, remember to price check and read reviews to be sure you’re getting the very best deal!
